Bailey Magers and Sunil Kumar cut strange figures on Pensacola Beach. Bags of disinfectant solution surrounded them on the white sand; their gloved hands juggled test tubes while layers of rubber and plastic shielded their skin from the elements. As the two organized their seawater samples on the popular Florida beach last August, an older woman wearing a swimsuit walked over to ask what they were doing.
“We’re just actively monitoring water quality,” they told her, but she pressed on.
“Are you looking for that flesh-eating bacteria?”
“We’re looking into it,” they replied, hoping not to frighten her. The woman turned back toward the ocean, her curiosity satisfied. As she walked away, Kumar noticed that she had scrapes and bruises on her body. A few minutes later, he watched her step into the waves. He shook off a chill and returned to the task at hand.
Magers and Kumar study a bacteria called Vibrio, part of a lineage of ancient marine species that likely emerged sometime around the Paleozoic Era. Enormous, shallow seas flooded the massive, interconnected supercontinents that constituted the Earth’s landmass at the time, and complex marine ecosystems developed that thrived in these temperate, freshly-formed bodies of water. Researchers think there are more than 70 Vibrio species in the environment today, hundreds of millions of years later. The organisms float in warm, brackish water, attaching themselves to plankton and algae and accumulating in prolific water-filtering species like clams and oysters.
A small number of Vibrio species can sicken and even kill. In worst-case scenarios, a person who has been exposed to the most dangerous of them — by swimming in brackish water with an open wound or ingesting a piece of raw shellfish that is contaminated with the tasteless and odorless toxin — may find themselves with only hours before the flesh on one or more extremities starts to bruise, swell, and decay. Without the quick aid of powerful antibiotics, septic shock can set in and lead to death. Anyone can get infected, though it is much more likely in people who have liver disease or are immunocompromised, elderly, or diabetic.
Climate change is making the world’s oceans, which have absorbed more than 90 percent of the excess heat trapped by greenhouse gas emissions, more hospitable to Vibrio. Research shows that temperature and salinity are the largest predictors of how widespread Vibrio bacteria are. As water temperatures rise, so does the concentration of Vibrio in seawater — boosting the risk of infection for beachgoers and shellfish consumers. The bacteria start getting active in water temperatures above 60 degrees Fahrenheit and multiply rapidly as coastal waters warm throughout the summer. In recent years, scientists have documented Vibrio expanding into places that were once too cold to support the bacteria, pushing as far north along the U.S. East Coast as Maine and appearing with more prevalence in temperate seas around the world.
Vibriosis infections in general are the leading cause of shellfish-related illness in the U.S. They have increased “more than any other illness caused by a pathogen in the U.S. food supply” since the Centers for Disease Control and Prevention, or CDC, started keeping tabs on such illnesses in 1996, according to a 2019 analysis by the International Association for Food Protection. The report attributed the precipitous rise to a “perfect storm” of factors that include climate change, food handling practices, expanding globalization, a patchwork of regulatory oversight, and improved diagnosis.
On their conspicuous expeditions to Pensacola and other Sunshine State beaches, Magers and Kumar are trying to understand where, and when, harmful Vibrio species are present across the state. The research they’re doing is part of an ongoing effort by a laboratory at the University of Florida to create a Vibrio early warning system for the eastern United States — a program that can alert public health departments to high Vibrio concentrations in any given area a month in advance. How many limbs would be saved, Magers wonders, if doctors and nurses could be warned ahead of time that their emergency rooms would soon see an uptick in these chronically underdiagnosed infections?
The work serves more than one purpose: As Vibrio bacteria spread north into cooler waters, they serve as a first warning signal of changing marine conditions — giving researchers a heads-up that the familiar composition of marine species in their local waters may be starting to shift. In Europe’s Baltic Sea, for example, a spike in Vibrio infections in July 2014 closely mirrored a heatwave that rapidly warmed the shallow sea. The incident showed researchers that Vibrio spikes herald unusually warm marine conditions — and they have since been utilized as barometers for ocean heatwaves and sea-surface warming patterns, not just food safety.
“We see Vibrio as the indicator for climate change,” said Kyle Brumfield, a microbiologist at the University of Maryland who has been studying the bacteria for a decade. “We can use the presence of Vibrio and Vibrio cases as a proxy for water health in general.”
The CDC estimates that about 80,000 cases of vibriosis occur in the U.S. every year, resulting in about 100 deaths. Of those 80,000 cases, most are caused by a Vibrio called parahaemolyticus, which most commonly results in gastroenteritis, or food poisoning. The vast majority of the deaths, however, are caused by a type of Vibrio called vulnificus — the Latin word for “wound-making.”
Vulnificus is so potent it can squeeze through a pinhole-sized cut in the skin and lead to death in just 24 hours. In the last five years, the CDC registered 429 such vulnificus cases, plus 136 foodborne cases. But even though foodborne cases are less numerous, the patients that contract vulnificus by eating contaminated shellfish are more likely to die than those infected via open wounds. Thirteen percent of those nonfoodborne cases died, compared to 32 percent of people who got the infection from eating seafood. Most cases occur in the Gulf and Atlantic coastal regions.
As far as infectious diseases go, vulnificus is exceedingly rare: The CDC reports between 150 and 200 cases a year. The sexually-transmitted disease chlamydia, by comparison, one of the most common bacterial infections in the U.S., infects northward of 1.5 million Americans annually. But vulnificus’ astonishing speed and high fatality rate — 15 to 50 percent, depending on the health of the person exposed and the route of infection — makes it a unique public health threat, particularly as climate change grows its pathways of exposure.
Vulnificus is not the kind of pathogen you’d want behaving erratically, but that’s exactly what it’s been doing since the late 2010s. Across the Eastern Seaboard, local and federal health officials have been reporting “unusual increases” in vulnificus prevalence — jagged spikes in infections that appear to correspond to extreme weather events like hurricanes and marine heatwaves.
In 2022 and 2024, years when the brackish water that Vibrio bacteria thrive in was pushed inland by major hurricanes, Florida’s public health department reported 17 and 19 deaths, respectively, linked to vulnificus exposure via open wounds. North Carolina, New York, and Connecticut also saw small clusters of infections during a record-breaking heatwave in the summer of 2023. “As coastal water temperatures increase,” the CDC warned in its investigation of those outbreaks, “V. vulnificus infections are expected to become more common.”
A 2023 study that analyzed a 30-year database of confirmed vulnificus infections from outdoor recreation along the U.S. Gulf and Atlantic coasts found the northern boundary of infections has moved north by a rate of 30 miles per year since 1998. The study noted that “V. vulnificus infections may expand their current range to encompass major population centers around New York,” and that annual case numbers may double as temperatures rise and America’s elderly population grows.
“In the 1980s, Vibrio abundance would increase in the late spring and stay high through the summer and drop in the middle of October,” Brumfield, who conducts research on Vibrio in Maryland, said. “Now … we can pretty much find them almost year-round.”
Just how worried we should be about the changing dynamics of Vibrio bacteria depends on who you ask and what you read. The gruesome and fast-acting nature of the vulnificus infection makes it enticing fodder for local and national news media, fueling a spree of terrifying reports every time a new severe infection or death surfaces. “Virginia dad wades in calf-high water, dies 2 weeks later of flesh-eating bacteria that ‘ravaged’ his legs,” read a recent headline in People magazine. “2 dead after eating oysters, contracting flesh-eating bacteria, officials say,” per a 2025 web story about two deaths linked to oyster consumption in Louisiana and Florida. Like many others in their mold, neither story mentions how rare the bacteria are.
The press is bad news for some in the seafood industry, which does not welcome a national conversation about the rise in vibriosis cases, vulnificus in particular. Shellfish farmers and industry representatives that Grist spoke to in Florida and New York argued media attention on the safety of their products is unwarranted. “‘Flesh-eating bacteria,’” said Leslie Sturmer, a researcher who works for the University of Florida’s shellfish aquaculture extension program and consults with the shellfish industry on research and regulation — “the media loves it.”
Paul McCormick, an oyster farmer in Long Island who sells 750,000 oysters a year, thinks all press is bad press. “Even if the title of your article says ‘New York oysters are the safest oysters in the universe,’” he told me on the phone from his office in East Moriches in January, “you’ve already created a problem.”
In unrefrigerated oysters left out in warm conditions, Vibrio bacteria reproduce every 20 minutes. But in 2010, states began deploying strict protocols known as “Vibrio control plans,” which require harvesters to rapidly cool their catch onboard and then refrigerate it at a shellfish processing facility within a set number of hours. The measures have proven effective at stopping the growth of Vibrio in harvested shellfish and preventing disease.
The fact that infections can happen in one of two ways — shellfish consumption and seawater exposure — makes it easy to shift blame and point fingers. Consumers have more control over how much exposure they have to Vibrio than they have with E. coli, for example. A person with a kidney condition can choose not to eat oysters on the half shell. E. Coli, often found in raw vegetables, is far tricker to avoid. Likewise, someone with an open wound can opt not to bathe in brackish waters if they are aware of the risks lurking in the surf.
For shellfish industry representatives, personal responsibility is the primary way to bring caseloads down. “The person is the risk,” said Sturmer. “Not the climate, not the water, not the bacteria.” Implicitly, this appears to be the government’s position as well: There is currently no numerical threshold at which state public health agencies will “shut down” a beach for outdoor recreation, though states will issue public advisories and, very rarely, close beaches if they happen to find high levels of Vibrio in the water.
But that perspective doesn’t account for the rapid marine changes brought on by climate change, the patchiness of vibriosis awareness, and the fact that Americans often make personal decisions that are at odds with their own health and safety.
The shellfishers Grist spoke to fully acknowledged the research underpinning Vibrio’s spread. McCormick studied environmental science in college, and Sturmer is running her own climate experiments in a laboratory in the fishing town of Cedar Key, Florida, putting different kinds of clams and oysters through heat stress tests to determine which species are best equipped to weather the decades ahead. Marine mollusks are uniquely threatened by rising ocean temperatures, ocean acidification, and sea level rise, issues that can lead to thin shells, low crop yields, and mass die-offs on farms. A detailed understanding of climate science, in other words, is good business for those who make their living fishing.
The problem, according to Sturmer, is that shellfishers have been unfairly singled out for a health issue that doesn’t affect most consumers and is more often contracted by ocean bathing rather than raw oyster consumption. While beaches stay open even when Vibrio bacteria are present in the water and lead to infections, a small number of foodborne vibriosis cases can trigger state closures of shellfish harvesting areas and product recalls. The National Centers for Coastal Ocean Science noted that these precautions “erode consumer confidence and likely decrease sales.”
The panic that ensues after media reports of Vibrio infections has a similar effect: A 2024 study asked more than 350 shellfish consumers in Rhode Island — a state that relies heavily on its shellfish industry, particularly in summer months when people vacation along the coastline — to bid on entrees of raw oysters and clams. After showing study participants a real newspaper article about a 2015 Vibrio outbreak linked to an oyster farm in Massachusetts, the researchers reported that the news had a “significant negative impact” on participants’ willingness to bid on oysters. It had a depressive effect on clam sales, too.
“You should really be out there beating the drum on botulism or salmonella or E. Coli,” Sturmer told me on a recent visit to her lab in Cedar Key. “Why worry about [vulnificus] when the number of cases are so minimal?” Sturmer is quick to point out that even the term “flesh-eating bacteria” is a misnomer. She’s right, in a sense: The bacteria doesn’t “eat” tissue; it destroys it. But it’s hard to say whether someone who has survived a bout of necrotizing fasciitis, the medical term for what vulnificus does to the flesh, would care to dispute the difference.
Protecting consumers from being sickened by the deadly bacteria isn’t as simple as trusting people with underlying medical conditions not to eat shellfish. Americans consume 2.5 billion oysters every year, half of which are eaten raw. Vibrio infections, which most often resemble food poisoning, are still underreported and underrecognized, even among individuals who are most at risk of developing a severe infection. Vulnificus infections are also underreported, but much less so than other Vibrio-related infections because they often require a hospital or emergency room visit.
“I’ve cared for many people with salmonella infections and water-borne infectious processes, but this is the one that is likely the most serious,” said Norman Beatty, an associate professor at the University of Florida College of Medicine who is also a practicing infectious disease doctor in Gainesville, and has seen limbs and lives lost to vulnificus.
When it comes to preventing Vibrio infections, the work Magers and Kumar are doing could take some of the onus off of individual responsibility. The researchers are identifying which parts of the eastern U.S. coastline will be most risky for overall vibriosis infections, and vulnificus specifically, as waters warm. Alongside a group of microbiologists from the University of Maryland, including Brumfield, the scientists have developed a computer model that can predict how high the vibriosis risk will be in any given coastal county on the Gulf or East coasts a month in advance. The team trained their model by pairing the CDC’s count of Vibrio-related foodborne and waterborne illnesses from 1997 to 2019 with satellite data that measures the conditions that fuel Vibrio growth, such as water temperature and salinity.
The system is far from perfect. When the model was first trained and evaluated, it was only 23 percent precise in pinpointing high-risk counties, meaning just one in four of the counties the program labeled as high-risk actually ended up seeing a vibriosis case in a given month. But it was very good at determining which counties were low-risk, capturing those regions with 99 percent precision. And it improved over time as the quality of the data they fed it got better. When they had the model do a test run on data collected by the Florida Department of Public Health from 2020 to 2024, 72 percent of total cases occurred in counties the tool flagged as high-risk for vibriosis.
Perhaps most significantly, the model was especially adept at predicting high-risk counties ahead of Hurricanes Helene and Milton in 2024 — more than 80 percent of the vibriosis cases that occurred in Florida in the aftermath of those hurricanes were reported in counties the model had already flagged as high-risk.
The tool is geared toward predicting water-borne infections, but it may also provide useful information to the shellfishing industry, though the system isn’t a replacement for the established protocols farmers already use — protocols that have proven to be effective, particularly in states that are aggressive about enforcing them. What the new tool could do, however, is supplement those Vibrio control plans, especially when an upcoming weather pattern deviates from the historical norm — something that has been happening a lot lately.
States currently use a rolling five-year average illness rate to calculate how many minutes or hours harvested shellfish can stay on a boat before moving into indoor refrigeration. In February, for example, Florida shellfishers have to get their oysters into refrigeration by 5 p.m. on the day of harvest. In July, they have no more than two hours, or they have to cool their catch in ice slurries on board. But these timetables don’t account for sudden temperature anomalies.
“It’s going to be 80 degrees this week in Alabama,” Andy DePaola, a Gulf Coast oyster farmer, told me in February. “Yet I can keep my oysters out for, like, 14 hours, because the rolling five-year average is 20 degrees less than that anomaly.” (DePaola is also a microbiologist who worked on Vibrio at the FDA for the better part of 40 years, and is the author of the 2019 analysis that diagnosed the “perfect storm” for Vibrio spread.)
But the shellfish industry doesn’t appear enthusiastic about the idea of assigning counties a risk category based on Vibrio prevalence. Vibrio researchers, by their own admission, haven’t done a good job of reaching out to shellfishers to find out how such a tool would work best for them. At an August meeting of the Delaware Bay Section of the New Jersey Shellfisheries Council last year, the director of a shellfish research laboratory brought up the idea of using Vibrio predictive models to “determine optimal days to harvest to reduce the transfer of infection to humans.” A lengthy discussion ensued. The consensus, ultimately, was that the model was a bad idea, and could be “used against the industry.”
Not all shellfishers are dead set against the kind of work Magers and Kumar are doing. “If Vibrio is an indicator of global warming, then that’s just an unfortunate bad luck scene for us,” McCormick, the Long Island oysterman, said. But it’s hard for him to see what relevance that research has to an industry that already has its own methods of controlling Vibrio. “In my mind that exists in one realm and the safety of our oysters is a whole different thing.”
As we move deeper into the 21st century, however, those two realms will have more overlap. If countries keep up their current pace of greenhouse gas emissions, most coastal communities along the East Coast will be environmentally primed for vibriosis outbreaks during peak summer months by midcentury. It won’t be a question of if there will be more vibriosis cases — it will be a matter of how to manage them. That’s the scenario Magers and Kumar are preparing for.
“In 30, 40, 100 years, these models won’t even matter because the risk is so high,” said Magers, the lead author of the predictive modeling study. “When it gets to that point, it would probably be a different kind of modeling strategy where we’d be modeling case numbers instead of infection risk.”

What is Vibrio?
Vibrio is a type of bacteria that has been around for hundreds of millions of years; researchers have identified more than 70 species. These species are mostly harmless, but some can cause infection. The bacteria thrive in warm, brackish (slightly salty) water such as estuaries and bays, attaching themselves to plankton and algae and accumulating in prolific water-filtering species like clams and oysters. Serious infections typically happen either through exposure to an open wound in saltwater or, more rarely, ingestion of raw shellfish that contain the bacteria.
The concentration of Vibrio in coastal waterways is higher from May through October, when temperatures are warmer. Most U.S. cases are in the Gulf and Atlantic coastal regions. Vibrio is tasteless and odorless. The Centers for Disease Control and Prevention, or CDC, estimates that about 80,000 cases of vibriosis (an infection caused by the Vibrio bacteria) occur in the U.S. every year, resulting in about 100 deaths. Florida has the highest number of cases, with about 20 percent reported from the Indian River Lagoon region, a popular recreation destination on the Atlantic Coast.
What happens if you come into contact with Vibrio?
Most people are not at risk of developing illness, or they may have only mild symptoms. However, those with compromised immune systems can develop life-threatening infections.
The majority of the 80,000 annual U.S. cases are caused by a Vibrio called parahaemolyticus, which most often infects people via the raw seafood they eat and usually leads to gastroenteritis, or food poisoning. The symptoms may include nausea, vomiting, diarrhea, stomach cramps, fever and chills, weakness, fatigue, and headache.
A different type of Vibrio, vulnificus, is much less common, but can cause severe illness. The infected wound may be red, swollen, and painful, or you may develop mild gastrointestinal issues such as watery diarrhea, stomach cramps, or vomiting. Symptoms typically appear within 12 to 24 hours and can last up to seven days. Healthy people tend to fight off the infection on their own. But if flesh on one or more extremities to bruise, swell, and decay, or symptoms of sepsis occur, it is a medical emergency. Vulnificus can squeeze through a pinhole-sized cut in the skin and lead to death in just 24 hours. This severe infection is rare, but it has a 15 to 50 percent fatality rate; the vast majority of the 100 annual deaths are from this strain. A severe vulnificus infection is much more likely in people who have liver disease or are immunocompromised, elderly, or diabetic.
How concerned should I be — and how do I stay safe?
You don’t necessarily need to avoid oyster bars or cancel your beach trip, but you should know how to stay informed and take precautions. Here are a few ways to do so:
How is climate change affecting Vibrio?
Climate change is making the world’s oceans, which have absorbed more than 90 percent of the excess heat trapped by greenhouse gas emissions, more hospitable to Vibrio. The bacteria start getting active in temperatures above 60 degrees Fahrenheit and multiply rapidly as waters warm throughout the summer. Vibrio is expanding into places that were once too cold to support it, farther north on the U.S. East coast and in other temperate seas around the world. As it spreads, it serves as a first warning signal of changing marine conditions.
What’s being done to address Vibrio?
There’s a lot of research happening to better understand the risks these bacteria pose under changing environmental conditions: A group of microbiologists at the University of Maryland, alongside other scientists, have developed a computer model that can predict how high the risk of vibriosis will be in any given coastal county in the eastern U.S. a month in advance. The team trained its model, which is still under development, by pairing the CDC’s count of Vibrio-related foodborne and waterborne illnesses from 1997 to 2019 with satellite data that measures the conditions that fuel Vibrio growth, such as water temperature and salinity. It’s far from perfect, but it’s improving. And it was especially adept at predicting high-risk counties ahead of hurricanes Helene and Milton in 2024 — more than 80 percent of the vibriosis cases that occurred in Florida in the aftermath of those hurricanes were reported in counties the model had already flagged as high-risk.

Earth Day 2026 arrives less than a week after Wisconsin was battered by a succession of unseasonably severe thunderstorms, hail and tornadoes. A lack of snow in the West this winter has raised fears of an especially difficult wildfire season — raising air quality concerns across the Upper Midwest this summer. The administration of President Donald Trump has made drastic changes to the budget and structure of agencies such as the EPA and U.S. Forest Service, reducing staff at agencies that manage air and water quality and protect public lands.
Nearly 60 years after Earth Day was founded by Wisconsin Gov. Gaylord Nelson, environmental advocates and elected officials celebrated the holiday noting the state, often labeled a “climate haven” for its easy access to fresh water and northern location, is not immune from the damaging effects of climate change. Still, they said, there are small victories happening every day across the state.
Gov. Tony Evers spent the week on a statewide tour touting efforts to plant more trees, conserve more land and use more sustainable sources of energy.
In 2021, Evers signed a pledge that Wisconsin would plant 75 million trees and conserve 125,000 acres of forestland by the end of 2030. In a Tuesday news release, Evers’ office announced that in 2025 the state planted nearly 12 million trees and conserved more than 7,800 acres of forestland in the state in 2025 — bringing the total to more than 54 million trees planted in five years.
“Conservation and protecting our natural resources are core to who we are as a people and as a state — it’s in our DNA, and here in Wisconsin, our work to conserve and protect our lands, waters, and air and respond to an ever-changing climate has never been more important,” Evers said in a statement. “From flooding and severe weather events to unseasonable snow droughts and everything in between, it’s clear that climate change is an imminent threat to our state, economy, and our kids’ future. That’s why, since Day One, my administration and I have been working to conserve our natural resources and tackle the climate crisis head-on, but there’s always more we can do.”
While Evers touts the work his administration has done to protect the state’s environment, the main tool the state has used to conserve public land for the last four decades — the Knowles-Nelson Stewardship Grant program — is set to expire this summer due to Republican opposition to land conservation and the Legislature’s inability to reach a deal to reauthorize the program before adjourning for the year.
Howard Lerner, president of the Environmental Law and Policy Center, said at an online news conference Tuesday that there are still wins happening for the climate.
“We are getting things done in the Midwest, even while the Trump administration maintains its assault on core environmental values and rolls back years and years of federal progress,” he said.
He noted that a variety of groups across the Midwest worked together to protect the funding in the federal Great Lakes Restoration Initiative. He added, however, that more work will have to be done to protect Great Lakes shoreline communities from the effects of an increasingly fluctuating water level.
“When all is said and done, the impacts of climate change are leading to much greater fluctuations in Great Lakes water levels, and they’re leading to more intensive storms, high winds, heavy waves that batter the shoreline,” he said. “That puts a heavy impact and burden on our shoreline communities and on the shoreline infrastructure, and that’s infrastructure that we’ve got to protect and find ways of doing that.”
But the Great Lakes are also struggling with water quality, he said, largely in the form of contamination from factory farms that can lead to toxic events such as algae blooms. He said that in the wake of the federal government stepping back from its role protecting wetlands and waterways from runoff, Midwest states need to do more.
“We need to get policies in the states that reduce the amount of phosphorus, nitrates that flow into the water supply,” he said. “I think you’re going to see that [concentrated animal feeding operations] are going to be a bigger story going forward. Communities don’t want them, and E. coli and local water supplies and more toxic algae blooms in the Great Lakes is something that the public, I just don’t think is willing to tolerate.”

The darkened sky in the early afternoon, the tornado sirens wailing as baseball-sized hail shattered windows and dented car roofs, sounding like a series of explosions as drivers hurried home at 4 p.m. last week — all of it felt like the eerie first scene in an apocalyptic movie.
This is not a drill, I thought, watching the clouds tumbling and boiling overhead as my car radio and my phone began shrieking in unison and a robotic voice informed me that I should take shelter immediately from a tornado that was moving at 20 miles per hour directly toward my neighborhood.
We’ve all grown accustomed to the low background hum of climate anxiety. Suddenly it’s as loud and immediate as the crack of a giant hailstone on the windshield.
The changes to the planet we’ve been warned about for decades are suddenly hitting too close to home to ignore. Over the last year in Wisconsin we’ve endured smoke-filled skies from summer forest fires, massive floods, wild temperature swings and scarier, more serious storms.
This should be a wakeup call. But instead of accelerating efforts to head off climate catastrophe, our federal government is canceling renewable energy contracts and pushing for more coal plants, more oil drilling, more toxic mining on public lands, undoing protections for clean air and water, and accelerating the destruction of our shared environment in order to extract resources and build more wealth for a handful of people in the short term.
The price of this heedlessness is so enormous it hurts just to think about it.
Two days after the hail storm and tornado warnings sent me and my neighbors scrambling for cover, the U.S. Senate passed a bill to allow sulfide mining in the Superior National Forest, on the edge of the Boundary Waters Canoe Area Wilderness — an inexpressibly beautiful place that is precious to my family, the scene of some of the most formative experiences of our girls’ childhood, and the most visited wilderness area in the U.S. The Forest Service spent years studying how acid mine drainage — the toxic byproduct of sulfide-ore mining — could contaminate the interconnected lakes and streams that make up the Boundary Waters. Once that contamination starts, there is no way to reverse it, which is why an overwhelming majority of Minnesotans weighed in against the mine, and the federal government blocked it. Until that protection was overturned last week.
Minnesota Sen. Tina Smith took a heroic stand on the Senate floor last Wednesday, arguing late into the night, trying to persuade her colleagues not just to hold off on destroying this pristine place, but to forgo using an obscure maneuver that, in a 50-49 vote, redefined land management and knocked down longstanding protections for every piece of national forest in the country.
My colleague J. Patrick Coolican, editor of the Minnesota Reformer, described Smith pleading to an empty chamber, “I dearly hope the members of this body will think about their legacy in protecting the great places in this country.”
No future president can reinstate the mining ban that protected the Boundary Waters now that Congress used the obscure Congressional Review Act to strike it down. And it’s bigger than that. With their vote to open up mining near the Boundary Waters, “lawmakers have called into question the validity of every management plan issued by the U.S. Forest Service over the past several decades,” Alex Brown of Stateline reports. “That could result in legal chaos for thousands of permits covering logging, grazing, mining and outdoor recreation.” As Smith warned her Republican colleagues who want to protect the public lands they cherish in their home states, their vote means it’s now open season on those lands, too.
I couldn’t bear to talk with my daughters, who have spent every summer they can remember in the Boundary Waters, about the vote last week.
But this week, Earth Week, it’s time to confront it. All is not lost. Just as they stood up to the masked federal agents who descended on Minneapolis to tear immigrant families apart, Minnesotans are organizing to fight Twin Metals, a wholly owned subsidiary of the Chilean mining company Antofagasta, as it seeks state permits to open up its toxic mine. While mining proponents tout the mine as a job creator (ignoring the economic costs of destroying the nation’s most-visited wilderness), the Senate’s action mostly benefits a foreign mining company, which has a history of flouting environmental regulations and creating toxic spills in other countries, and which will likely sell the copper it extracts from Minnesota to China.
The least we Wisconsinites can do is to help our neighbors as they try to repel this deadly invasion and seizure of a priceless natural resource.
Friends of the Boundary Waters, based in Minnesota, is filing a lawsuit arguing that the congressional maneuver that opened up the mine is illegal. The group and its allies are also urging the Minnesota DNR to cancel Twin Metals’ leases for the mine, and pushing the Minnesota state legislature to ban mining in this sensitive area.
As Wisconsin Sen. Gaylor Nelson, the founder of Earth Day put it in his 1970 speech kicking off the modern environmental movement, protecting the environment is “not just an issue of survival, but an issue of how we survive.”
“Our goal is not just an environment of clean air and water and scenic beauty,” he said. “….Our goal is an environment of decency, quality and mutual respect for all human beings and all other living creatures. An environment without ugliness, without ghettos, without poverty, without discrimination, without hunger and without war.”
We need to protect that vision of life from the forces of greed and destruction that are engulfing us. We can’t let them write the end of the story.

Climate researchers predict storms that produce golf ball-size or larger hail will become more frequent, thanks to climate change.
According to a 2024 study by Northern Illinois University, a warmer climate increases water vapor in the air, which provides energy for thunderstorms like those seen April 14, 2026, in Wisconsin that produced large hail.
Hail is created when strong updrafts of air are pushed up into the colder atmosphere, freezing water droplets and pushing them around, making the droplets bigger and bigger. Eventually, those hailstones get too heavy and fall to earth.
“Our study suggests golf ball-size hail or larger will become more common because of more atmospheric instability, which leads to stronger thunderstorm updrafts,” NIU Atmospheric Science Professor Victor Gensini said.
A 2017 study in Nature that looked at historic patterns and forecasts also found hailstone size is expected to increase due to climate change.

Milwaukee County Executive David Crowley and County Board President Marcelia Nicholson-Bovell signed legislation Wednesday afternoon reaffirming the county’s commitment to adhering to the goals of the 2016 Paris Climate agreement.
“In Milwaukee County, we know that the climate crisis is a real, pressing threat to our environment, our economy, our health, and our quality of life,” Crowley said at the gathering beside other officials at the Urban Ecology Center of Washington Park.
The international agreement called on nations to adopt policies to keep average global temperatures from increasing more than 2 degrees Celsius above pre-industrial levels. The United States joined nearly 200 global nations and states in signing onto the agreement under President Barack Obama. President Donald Trump pulled out of the agreement after he was sworn into office in 2017 and, after President Joe Biden rejoined the agreement, again in 2025. Trump has called the agreement “unfair,” “one-sided,” and a “rip-off.” Since the Trump administration exited the agreement, state and local governments across the country have signaled their aims to stick with the agreement’s aims.
Milwaukee County first signed onto the Paris Climate Accords in 2017. The county’s goal is to reach net-zero operational emissions by 2050. The event Wednesday was held on the first day of Earth Month.
Crowley praised Milwaukee’s efforts towards reducing carbon emissions and climate resiliency despite being in a time “when federal climate leadership is stepping back.” He said at the event that the county has reduced its emissions by nearly 50% since 2005.
Nicholson-Bovell echoed the sentiment.
“Milwaukee County continues leading the way in the march toward a more environmentally sustainable community,” she said. “Our legislation recommits Milwaukee County to the Paris Agreement and Greenhouse Gas Endangerment Finding, because our children’s future depends on how we combat the climate crisis and build the equitable future we all deserve.”
Crowley and Nicholson-Bovell were joined by Milwaukee County Supervisors Felesia Martin, Anne O’Connor and Sky Capriolo.
The Urban Ecology Center itself is an example of the steps Milwaukee County has taken towards reaching net-zero. The Washington Park center was recently renovated, becoming the first all-electric non-residential building in Milwaukee County, the center’s executive director, Jen Hense, explained.
Now the building creates zero emissions and, with the planned installation of 100 new solar panels next week, is set to reduce its energy consumption by about one-third.
When the building was renovated, about 60% of its original structure was re-used. Some of the wood used in the renovations was also reclaimed from trees felled by Milwaukee County to combat the emerald ash borer insect. Bird-safe glass had also been installed, so far decreasing the number of collisions the building is responsible for. Surrounding the ecology center are ponds where people often fish, and the center works to re-introduce native plants to assist local ecosystems.
Hense stressed the importance of the Urban Ecology Center’s work. There are over 35,000 young people who attend outdoor and science programs at the county’s three Urban Ecology Centers, and more than 600,000 people visit the green spaces the center stewards in Riverside Park, Washington Park, and Menomonee Valley.
“We know that these natural spaces, and hundreds more across the county — that are loved and cared for by amazing individuals and incredible environmental organizations — are important to our community, and are essential to protect for generations to come,” said Hense. “We know that combatting the global climate crisis can start right here in the county, and that this work is truly an act of environmental justice.”
Nicholson-Bovell recalled growing up in a Milwaukee neighborhood where the nearest park didn’t have grass. She said that she was born premature with under-developed lungs, a condition worsened by the air pollution in her community. Studies have shown that increasing the number of urban trees would help improve polluted air conditions.
“The environment that I grew up in had been ripped apart by the building of a freeway,” said Nicholson-Bovell. “And it was little kids like me who struggled to breathe in our communities. We didn’t have access to clean air, we didn’t have access to green space. And when I became a Milwaukee County supervisor, I promised that no child that I could help support would ever have to experience that again.”
Crowley said visiting the county’s parks reminds him “of just how lucky we are to have accessible access to beautiful green spaces like the one that we are in today.” He stressed that having this “in our backyard” should never be “taken for granted” while highlighting the success the county has already achieved at reducing its climate impact. “And it is because, and through, our office of sustainability that we remain focused on building green infrastructure, creating local sustainability jobs, and making sure that every single neighborhood is part of our climate solution,” said Crowley.
Crowley said that partnership and collaboration with higher levels of government will be needed to fully accomplish the county’s climate goals. Yet that assistance is unlikely to come from the current federal government. Trump has repeatedly called climate change a hoax. Under Trump, the Environmental Protection Agency also repealed the 2009 endangerment finding that greenhouse gases threaten public health. During both Trump Administrations, climate data and even the words “climate change” have been purged from federal websites. Climate policies at the state level have also been blocked or frustrated by Wisconsin’s Republican-controlled legislature.
Grant Helle, director of the Milwaukee County Office of Sustainability, said that “while federal climate leadership declines, Milwaukee County is taking action.” Helle said that local action is “not optional, but essential.” Helle noted that the new Marcia P. Coggs Health and Human Services Center will have on-site solar which will off-set over 11% of that facility’s energy use. The county is also re-thinking how building design could impact climate change, an issue which Helle said residents are concerned about.
A stream of extreme weather events in recent months and years have likely fueled those concerns. Just weeks ago, people in parts of Wisconsin endured a historic blizzard, receiving so much snow that plow services needed to be shut down. Some Milwaukee communities still haven’t fully recovered from record-breaking amounts of rain and flooding that swept through the city in August. The Trump Administration has denied multiple requests for assistance and flood relief made by Wisconsin communities.
Extreme heat gripped areas of the state in 2023, coinciding with increased wildfire activity within the state, while smoke from fires in Canada worsened air quality. Severe storms also hit Milwaukee and other Wisconsin communities in 2022 and 2021. O’Connor recalled the floods of 2010, where people were “literally canoeing down the street where I live in my district.”
Crowley said that the August floods should be an indication that the midwest is not safe from climate change.
“That tells us how do we build infrastructure that is resilient, and how do we think long term making sure that this planet is continuously livable for our young people and for many generations moving forward,” he said.
Nicholson-Bovell said that the floods were devastating, but that climate change is a national issue. “My husband I met in St. Louis,” she said. “They had a historic tornado rip through the inner-city of St. Louis and they’re still scrambling to try and find housing for individuals.”
Helle said that increased flooding, harsher heatwaves, and worse air quality are climate hazards Milwaukeeans are already experiencing. “It’s really unfortunate,” said Helle. “But what it does is go to show that we need to continue to make efforts here in Milwaukee County right now where we can to lower the impact on those residents that we ultimately serve.”

For decades, corn has reigned over American agriculture. It sprawls across 90 million acres — about the size of Montana — and goes into everything from livestock feed and processed foods to the ethanol blended into most of the nation’s gasoline.
But a growing body of research reveals that America’s obsession with corn has a steep price: The fertilizer used to grow it is warming the planet and contaminating water.
Corn is essential to the rural economy and to the world’s food supply, and researchers say the problem isn’t the corn itself. It’s how we grow it.
Corn farmers rely on heavy fertilizer use to sustain today’s high yields. And when that nitrogen breaks down in the soil, it releases nitrous oxide, a greenhouse gas nearly 300 times more potent than carbon dioxide. Producing nitrogen fertilizer also emits large amounts of carbon dioxide, adding to its climate footprint.
Agriculture accounts for more than 10% of U.S. greenhouse gas emissions, and corn uses more than two-thirds of all nitrogen fertilizer nationwide — making it the leading driver of agricultural nitrous oxide emissions, studies show.
The corn and ethanol industries insist that rapid growth in ethanol — which now consumes more than 40% of the U.S. corn crop — is a net environmental benefit, and they strongly dispute research suggesting otherwise.
Since 2000, U.S. corn production has surged almost 50%, further adding to the crop’s climate impact.
Yet the environmental costs of corn rarely make headlines or factor into political debates. Much of the dynamic traces back to federal policy — and to the powerful corn and ethanol lobby that helped shape it.
The Renewable Fuel Standard, passed in the mid 2000s, required that gasoline be blended with ethanol, a biofuel that in the United States comes almost entirely from corn. That mandate drove up demand and prices for corn, spurring farmers to plant more of it.
Many plant corn year after year on the same land. The practice, called “continuous corn,” demands massive amounts of nitrogen fertilizer and drives especially high nitrous oxide emissions.
At the same time, federal subsidies make it more lucrative to grow corn than to diversify. Taxpayers have covered more than $50 billion in corn insurance premiums over the past 30 years, according to federal data compiled by the Environmental Working Group.
Researchers say proven conservation steps — such as planting rows of trees, shrubs and grasses in corn fields — could sharply reduce these emissions. But the Trump administration has eliminated many of the incentives that helped farmers try such practices.
Experts say it all raises a larger question: If America’s most widely planted crop is worsening climate change, shouldn’t we begin growing it a different way?
Corn has been a staple of U.S. agriculture for centuries, first domesticated by Native Americans and later used by European immigrants as a versatile crop for food and animal feed. Its production really took off in the 2000s after federal mandates and incentives helped turn much of America’s corn crop into ethanol.
Corn’s dominance — and the emissions that come with it — didn’t happen by accident. It was built through a high-dollar lobbying campaign that continues today.
In the late 1990s, America’s corn farmers were in trouble. Prices had cratered amid a global grain glut and the Asian financial crisis. A 1999 report by the Federal Reserve Bank of Minneapolis said crop prices had hit “rock bottom.”
In 2001 and 2002, the federal government gave corn farmers and ethanol producers a boost — first through the U.S. Department of Agriculture’s Bioenergy Program, which paid ethanol producers to increase their use of farm commodities for fuel. Then the 2002 Farm Bill created programs that continue to support ethanol and other renewable energy.
Corn growers soon after mounted an all-out campaign in Washington. Their goal: persuade Congress to require gasoline to be blended with ethanol. State and national grower groups lobbied relentlessly, pitching ethanol as a way to cut greenhouse gasses, reduce oil dependence and revive rural economies.
“We got down to a couple of votes in Congress, and the corn growers were united like never before,” recalled Jon Doggett, then the industry’s chief lobbyist, in an article published by the National Corn Growers Association. “I started receiving calls from Capitol Hill saying, ‘Would you have your growers stop calling us? We are with you.’ I had not seen anything like it before and haven’t seen anything like it since.”
Their persistence paid off. In 2005, Congress created the Renewable Fuel Standard (RFS), which requires that a certain amount of ethanol be blended into U.S. gasoline each year. Two years later, lawmakers expanded it further. The policy transformed the market: The amount of corn used for ethanol domestically has more than tripled in the past 20 years.
When demand for corn spiked as a result of the RFS, it pushed up prices worldwide, said Tim Searchinger, a researcher at Princeton University’s School of Public and International Affairs. The result, Searchinger said, is that more land around the world got cleared to grow corn. That, in turn, resulted in more emissions.
That lobbying brought clout. “King Corn” became a political force, courted by presidential hopefuls and protected by both parties. Since 2010, national corn and ethanol trade groups have spent more than $55 million on lobbying and millions more on political donations, according to campaign finance records analyzed by Floodlight.
In 2024 alone, those trade groups spent twice as much on lobbying as the National Rifle Association. Major industry players — Archer Daniels Midland, Cargill and ethanol giant POET among them — have poured even more into Washington, ensuring the sector’s voice remains one of the loudest in U.S. agriculture.
Now those same groups are pushing for the next big prize: expanding higher-ethanol gasoline blends and positioning ethanol-based jet fuel as aviation’s “low-carbon” future.
Corn and ethanol trade groups didn’t make their officials available for interviews.
But on their websites and in their literature, they have promoted corn ethanol as a climate-friendly fuel.
The Renewable Fuels Association cites government and university research that finds burning ethanol reduces greenhouse gas emissions by roughly 40-50% compared with gasoline. The ethanol industry says the climate critics have it wrong — and that most of the corn used for fuel comes from better yields and smarter farming, not from plowing up new land. The amount of fertilizer required to produce a bushel of corn has dropped sharply in recent decades, they say.
“Ethanol reduces carbon emissions, removing the carbon equivalent of 12 million cars from the road each year,” according to the Renewable Fuels Association.
Growth Energy, a major ethanol trade group, said in a written statement that U.S. farmers and biofuel producers are “constantly finding new ways to make their operations more efficient and more environmentally beneficial,” using things like cover crops to reduce their carbon footprint.
But some research tells a different story.
A recent Environmental Working Group report finds that the way corn is grown in much of the Midwest — with the same fields planted in corn year after year — carries a heavy climate cost.
Research in 2022 by agricultural land use expert Tyler Lark and colleagues links the Renewable Fuel Standard to expanded corn cultivation, heavier fertilizer use, worsening water pollution and increased emissions. Scientists typically convert greenhouse gases like nitrous oxide and methane into their carbon dioxide equivalents — or carbon intensity — so their warming impacts can be compared on the same scale.
“The carbon intensity of corn ethanol produced under the RFS is no less than gasoline and likely at least 24% higher,” the authors concluded.
Lark’s research has been disputed by scientists at Argonne National Laboratory, Purdue University and the University of Illinois, who published a formal rebuttal arguing the study relied on “questionable assumptions” and faulty modeling — a charge Lark’s team has rejected.
A 2017 report by the U.S. Government Accountability Office found that the RFS was unlikely to meet its greenhouse gas goals because the U.S. relies predominantly on corn ethanol and produces relatively little of the cleaner, advanced biofuels made from waste.
The problem isn’t just emissions, researchers say. Corn ethanol requires millions of acres that could instead be used for food crops or more efficient energy sources. One recent study found that solar panels can generate as much energy as corn ethanol on roughly 3% of the land.
“It’s just a terrible use of land,” Searchinger, the Princeton researcher, said of ethanol. “And you can’t solve climate change if you’re going to make such terrible use of land.”
Most of the country’s top crop isn’t feeding people. More than 40% of U.S. corn goes to ethanol. A similar amount is used to feed livestock, and just 12% ends up as food or in other uses.
Globally, corn production doubled from 2000 to 2021.
That growth has been fueled by fertilizer, which emits nitrous oxide that can linger in the atmosphere for more than a century. That eats away at the ozone layer, which blocks most of the sun’s harmful ultraviolet radiation.
Global emissions have soared alongside corn production. Between 1980 and 2020, nitrous oxide emissions from human activity climbed 40%, the Global Carbon project found.
In the United States, nitrous oxide emissions from agriculture in 2022 were equal to roughly 262 million metric tons of carbon dioxide, according to the EPA’s inventory of greenhouse gas emissions. That’s equivalent to putting almost 56 million passenger cars on the road.
The biggest increases are coming straight from the Corn Belt.
Ethanol’s climate footprint isn’t the only concern. The nitrogen used to grow corn and other crops is also a key source of drinking water pollution.
According to a new report by the Alliance for the Great Lakes and Clean Wisconsin, more than 90% of nitrate contamination in Wisconsin’s groundwater is linked to agricultural sources — mostly synthetic fertilizer and manure.
The same analysis estimates that in 2022, farmers applied more than 16 million pounds of nitrogen beyond what crops needed, sending runoff into wells, streams and other water systems.
For families like Tyler Frye’s, that hits close to home. In 2022, Frye and his wife moved into a new home in the rural village of Casco, Wisconsin, about 20 miles east of Green Bay. A free test soon afterward found their well water had nitrate levels more than twice the EPA’s safe limit. “We were pretty shocked,” he said.
Frye installed a reverse-osmosis system in the basement and still buys bottled water for his wife, who is breastfeeding their daughter, born in July.
One likely culprit, he suspects, are the cornfields less than 200 yards from his home.
“Crops like corn require a lot of nitrogen,” he said. “A lot of that stuff, I assume, is getting into the well water and surface water.”
When he watches manure or fertilizer being spread on nearby fields, he said, one question nags him: “Where does that go?”
Reducing corn’s climate footprint is possible — but the farmers trying to do it are swimming against the policy tide.
The One Big Beautiful Bill Act, backed by President Donald Trump and congressional Republicans, strips out the provisions of President Joe Biden’s Inflation Reduction Act that had rewarded farmers for climate-friendly practices.
And in April, Trump’s USDA canceled the $3 billion Partnerships for Climate-Smart Commodities initiative, a grant program designed to promote farming and forestry practices to improve soil and reduce greenhouse gas emissions. The agency said that the program’s administrative costs meant too little money was reaching farmers, while Agriculture Secretary Brooke Rollins dismissed it as part of the “green new scam.”
University of Iowa professor Silvia Secchi said the rollback of the Climate-Smart program has already given farmers “cold feet” about adopting conservation practices. “The impact of this has been devastating,” said Secchi, a natural resources economist who teaches at the university’s School of Earth, Environment and Sustainability.
Research shows what’s possible if farmers had support. In its recent report, the Environmental Working Group found that four proven conservation practices — including planting trees, shrubs and hedgerows in corn fields — could make a measurable difference.
Implementing those practices on just 4% of continuous corn acres across Illinois, Iowa, Minnesota and Wisconsin would cut total greenhouse gas emissions by the equivalent of taking more than 850,000 gasoline cars off the road, EWG found.
Despite setbacks at the federal level, some farmers are already showing what a more climate-friendly Corn Belt could look like.
In northern Iowa, Wendy Johnson farms 1,200 acres of corn and soybeans with her father. On 130 of those acres, she’s trying something different: She’s planting fruit and nut trees, organic grains, shrubs and other plants that need little or no nitrogen fertilizer.
“The more perennials we can have on the ground, the better it is for the climate,” she said.
Across the rest of the farm, they enrich the soil by rotating crops and planting cover crops. They’ve also converted less productive parts of the fields into “prairie strips” — bands of prairie grass that store carbon and require no fertilizer.
Under the now-canceled Climate-Smart grant program, they were supposed to receive technical assistance and about $20,000 a year to expand those practices. The grant program was terminated before they got any of the money.
“It’s hard to take risks on your own,” Johnson said. “That’s where federal support really helps. Because agriculture is a high-risk occupation.”
The economics still favor business as usual. Johnson knows that many Midwestern corn growers feel pressure to maximize yields, keeping them hooked on corn — and nitrogen fertilizer.
“I think a lot of farmers around here are very allergic to trees,” she joked.
In southeast Iowa, sixth-generation farmer Levi Lyle, who mixes organic and conventional methods across 290 acres, uses a three-year rotation, extensive cover crops and a technique called roller-crimping — flattening rye each spring to create a mulch that suppresses weeds, feeds the soil and reduces fertilizer needs.
“The roller crimping of cover crops is a huge, huge opportunity to sequester more carbon, improve soil health, save money on chemicals and still get a similar yield,” he said.
But farmers get few government incentives to take such climate-friendly steps, Lyle said. “There is a lack of seriousness about supporting farmers to implement these new practices,” he said.
And without federal programs to offset the risk, the innovations that Lyle and Johnson are trying remain exceptions — not the norm.
Many farmers still see prairie strips or patches of trees as a waste, said Luke Gran, whose company helps Iowa farmers establish perennials.
“My eyes do not lie,” Gran said. “I have not seen extensive change to cover cropping or tillage across the broad acreage of this state that I love.”
Despite mounting research about corn’s climate costs, industry groups are pushing for policies to boost ethanol demand.
One big priority: pushing a bill to require that new cars are able to run on gas with more ethanol than what’s commonly sold today.
Corn and biofuel trade groups have also been pressing Democrats and Republicans in Congress for legislation to pave the way for ethanol-based jet fuel. While use of such “sustainable” aviation fuel is still in its early stages domestically, corn and biofuel associations have made developing a market for it a top policy priority.
Secchi, the Iowa professor, says it’s easy to see why ethanol producers are trying to expand their market: The growth in electric vehicles threatens long-term gasoline sales.
Researchers warn that producing enough ethanol-based jet fuel could trigger major land use shifts. A 2024 World Resources Institute analysis found that meeting the federal goal of 35 billion gallons of ethanol jet fuel would require about 114 million acres of corn — roughly 20% more corn acreage than the U.S. already plants for all purposes. That surge in demand, the authors concluded, would push up food prices and worsen hunger.
Secchi calls that scenario a climate and land use “disaster.” Large-scale use of ethanol-based aviation fuel, she said, would mean clearing even more land and pouring on even more nitrogen fertilizer, driving up greenhouse gas emissions.
“The result,” she said, “would be essentially to enshrine this dysfunctional system that we created.”

Jessika Trancik, a professor in MIT’s Institute for Data, Systems, and Society, has been named the new director of the Sociotechnical Systems Research Center (SSRC), effective July 1. The SSRC convenes and supports researchers focused on problems and solutions at the intersection of technology and its societal impacts.
Trancik conducts research on technology innovation and energy systems. At the Trancik Lab, she and her team develop methods drawing on engineering knowledge, data science, and policy analysis. Their work examines the pace and drivers of technological change, helping identify where innovation is occurring most rapidly, how emerging technologies stack up against existing systems, and which performance thresholds matter most for real-world impact. Her models have been used to inform government innovation policy and have been applied across a wide range of industries.
“Professor Trancik’s deep expertise in the societal implications of technology, and her commitment to developing impactful solutions across industries, make her an excellent fit to lead SSRC,” says Maria C. Yang, interim dean of engineering and William E. Leonhard (1940) Professor of Mechanical Engineering.
Much of Trancik’s research focuses on the domain of energy systems, and establishing methods for energy technology evaluation, including of their costs, performance, and environmental impacts. She covers a wide range of energy services — including electricity, transportation, heating, and industrial processes. Her research has applications in solar and wind energy, energy storage, low-carbon fuels, electric vehicles, and nuclear fission. Trancik is also known for her research on extreme events in renewable energy availability.
A prolific researcher, Trancik has helped measure progress and inform the development of solar photovoltaics, batteries, electric vehicle charging infrastructure, and other low-carbon technologies — and anticipate future trends. One of her widely cited contributions includes quantifying learning rates and identifying where targeted investments can most effectively accelerate innovation. These tools have been used by U.S. federal agencies, international organizations, and the private sector to shape energy R&D portfolios, climate policy, and infrastructure planning.
Trancik is committed to engaging and informing the public on energy consumption. She and her team developed the app carboncounter.com, which helps users choose cars with low costs and low environmental impacts.
As an educator, Trancik teaches courses for students across MIT’s five schools and the MIT Schwarzman College of Computing.
“The question guiding my teaching and research is how do we solve big societal challenges with technology, and how can we be more deliberate in developing and supporting technologies to get us there?” Trancik said in an article about course IDS.521/IDS.065 (Energy Systems for Climate Change Mitigation).
Trancik received her undergraduate degree in materials science and engineering from Cornell University. As a Rhodes Scholar, she completed her PhD in materials science at the University of Oxford. She subsequently worked for the United Nations in Geneva, Switzerland, and the Earth Institute at Columbia University. After serving as an Omidyar Research Fellow at the Santa Fe Institute, she joined MIT in 2010 as a faculty member.
Trancik succeeds Fotini Christia, the Ford International Professor of Social Sciences in the Department of Political Science and director of IDSS, who previously served as director of SSRC.

As a major contributor to global carbon dioxide (CO2) emissions, the transportation sector has immense potential to advance decarbonization. However, a zero-emissions global supply chain requires re-imagining reliance on a heavy-duty trucking industry that emits 810,000 tons of CO2, or 6 percent of the United States’ greenhouse gas emissions, and consumes 29 billion gallons of diesel annually in the U.S. alone.
A new study by MIT researchers, presented at the recent American Society of Mechanical Engineers 2024 International Design Engineering Technical Conferences and Computers and Information in Engineering Conference, quantifies the impact of a zero-emission truck’s design range on its energy storage requirements and operational revenue. The multivariable model outlined in the paper allows fleet owners and operators to better understand the design choices that impact the economic feasibility of battery-electric and hydrogen fuel cell heavy-duty trucks for commercial application, equipping stakeholders to make informed fleet transition decisions.
“The whole issue [of decarbonizing trucking] is like a very big, messy pie. One of the things we can do, from an academic standpoint, is quantify some of those pieces of pie with modeling, based on information and experience we’ve learned from industry stakeholders,” says ZhiYi Liang, PhD student on the renewable hydrogen team at the MIT K. Lisa Yang Global Engineering and Research Center (GEAR) and lead author of the study. Co-authored by Bryony DuPont, visiting scholar at GEAR, and Amos Winter, the Germeshausen Professor in the MIT Department of Mechanical Engineering, the paper elucidates operational and socioeconomic factors that need to be considered in efforts to decarbonize heavy-duty vehicles (HDVs).
Operational and infrastructure challenges
The team’s model shows that a technical challenge lies in the amount of energy that needs to be stored on the truck to meet the range and towing performance needs of commercial trucking applications. Due to the high energy density and low cost of diesel, existing diesel drivetrains remain more competitive than alternative lithium battery-electric vehicle (Li-BEV) and hydrogen fuel-cell-electric vehicle (H2 FCEV) drivetrains. Although Li-BEV drivetrains have the highest energy efficiency of all three, they are limited to short-to-medium range routes (under 500 miles) with low freight capacity, due to the weight and volume of the onboard energy storage needed. In addition, the authors note that existing electric grid infrastructure will need significant upgrades to support large-scale deployment of Li-BEV HDVs.
While the hydrogen-powered drivetrain has a significant weight advantage that enables higher cargo capacity and routes over 750 miles, the current state of hydrogen fuel networks limits economic viability, especially once operational cost and projected revenue are taken into account. Deployment will most likely require government intervention in the form of incentives and subsidies to reduce the price of hydrogen by more than half, as well as continued investment by corporations to ensure a stable supply. Also, as H2-FCEVs are still a relatively new technology, the ongoing design of conformal onboard hydrogen storage systems — one of which is the subject of Liang’s PhD — is crucial to successful adoption into the HDV market.
The current efficiency of diesel systems is a result of technological developments and manufacturing processes established over many decades, a precedent that suggests similar strides can be made with alternative drivetrains. However, interactions with fleet owners, automotive manufacturers, and refueling network providers reveal another major hurdle in the way that each “slice of the pie” is interrelated — issues must be addressed simultaneously because of how they affect each other, from renewable fuel infrastructure to technological readiness and capital cost of new fleets, among other considerations. And first steps into an uncertain future, where no one sector is fully in control of potential outcomes, is inherently risky.
“Besides infrastructure limitations, we only have prototypes [of alternative HDVs] for fleet operator use, so the cost of procuring them is high, which means there isn’t demand for automakers to build manufacturing lines up to a scale that would make them economical to produce,” says Liang, describing just one step of a vicious cycle that is difficult to disrupt, especially for industry stakeholders trying to be competitive in a free market.
Quantifying a path to feasibility
“Folks in the industry know that some kind of energy transition needs to happen, but they may not necessarily know for certain what the most viable path forward is,” says Liang. Although there is no singular avenue to zero emissions, the new model provides a way to further quantify and assess at least one slice of pie to aid decision-making.
Other MIT-led efforts aimed at helping industry stakeholders navigate decarbonization include an interactive mapping tool developed by Danika MacDonell, Impact Fellow at the MIT Climate and Sustainability Consortium (MCSC); alongside Florian Allroggen, executive director of MITs Zero Impact Aviation Alliance; and undergraduate researchers Micah Borrero, Helena De Figueiredo Valente, and Brooke Bao. The MCSC’s Geospatial Decision Support Tool supports strategic decision-making for fleet operators by allowing them to visualize regional freight flow densities, costs, emissions, planned and available infrastructure, and relevant regulations and incentives by region.
While current limitations reveal the need for joint problem-solving across sectors, the authors believe that stakeholders are motivated and ready to tackle climate problems together. Once-competing businesses already appear to be embracing a culture shift toward collaboration, with the recent agreement between General Motors and Hyundai to explore “future collaboration across key strategic areas,” including clean energy.
Liang believes that transitioning the transportation sector to zero emissions is just one part of an “energy revolution” that will require all sectors to work together, because “everything is connected. In order for the whole thing to make sense, we need to consider ourselves part of that pie, and the entire system needs to change,” says Liang. “You can’t make a revolution succeed by yourself.”

Climate anxiety affects nearly half of young people aged 16-25. Students like second-year Rachel Mohammed find hope and inspiration through her involvement in innovative climate solutions, working alongside peers who share her determination. “I’ve met so many people at MIT who are dedicated to finding climate solutions in ways that I had never imagined, dreamed of, or heard of. That is what keeps me going, and I’m doing my part,” she says.
Hydrogen-fueled engines
Hydrogen offers the potential for zero or near-zero emissions, with the ability to reduce greenhouse gases and pollution by 29 percent. However, the hydrogen industry faces many challenges related to storage solutions and costs.
Mohammed leads the hydrogen team on MIT’s Electric Vehicle Team (EVT), which is dedicated to harnessing hydrogen power to build a cleaner, more sustainable future. EVT is one of several student-led build teams at the Edgerton Center focused on innovative climate solutions. Since its founding in 1992, the Edgerton Center has been a hub for MIT students to bring their ideas to life.
Hydrogen is mostly used in large vehicles like trucks and planes because it requires a lot of storage space. EVT is building their second iteration of a motorcycle based on what Mohammed calls a “goofy hypothesis” that you can use hydrogen to power a small vehicle. The team employs a hydrogen fuel cell system, which generates electricity by combining hydrogen with oxygen. However, the technology faces challenges, particularly in storage, which EVT is tackling with innovative designs for smaller vehicles.
Presenting at the 2024 World Hydrogen Summit reaffirmed Mohammed’s confidence in this project. “I often encounter skepticism, with people saying it’s not practical. Seeing others actively working on similar initiatives made me realize that we can do it too,” Mohammed says.
The team’s first successful track test last October allowed them to evaluate the real-world performance of their hydrogen-powered motorcycle, marking a crucial step in proving the feasibility and efficiency of their design.
MIT’s Sustainable Engine Team (SET), founded by junior Charles Yong, uses the combustion method to generate energy with hydrogen. This is a promising technology route for high-power-density applications, like aviation, but Yong believes it hasn’t received enough attention. Yong explains, “In the hydrogen power industry, startups choose fuel cell routes instead of combustion because gas turbine industry giants are 50 years ahead. However, these giants are moving very slowly toward hydrogen due to its not-yet-fully-developed infrastructure. Working under the Edgerton Center allows us to take risks and explore advanced tech directions to demonstrate that hydrogen combustion can be readily available.”
Both EVT and SET are publishing their research and providing detailed instructions for anyone interested in replicating their results.
Running on sunshine
The Solar Electric Vehicle Team powers a car built from scratch with 100 percent solar energy.
The team’s single-occupancy car Nimbus won the American Solar Challenge two years in a row. This year, the team pushed boundaries further with Gemini, a multiple-occupancy vehicle that challenges conventional perceptions of solar-powered cars.
Senior Andre Greene explains, “the challenge comes from minimizing how much energy you waste because you work with such little energy. It’s like the equivalent power of a toaster.”
Gemini looks more like a regular car and less like a “spaceship,” as NBC’s 1st Look affectionately called Nimbus. “It more resembles what a fully solar-powered car could look like versus the single-seaters. You don’t see a lot of single-seater cars on the market, so it’s opening people’s minds,” says rising junior Tessa Uviedo, team captain.
All-electric since 2013
The MIT Motorsports team switched to an all-electric powertrain in 2013. Captain Eric Zhou takes inspiration from China, the world’s largest market for electric vehicles. “In China, there is a large government push towards electric, but there are also five or six big companies almost as large as Tesla size, building out these electric vehicles. The competition drives the majority of vehicles in China to become electric.”
The team is also switching to four-wheel drive and regenerative braking next year, which reduces the amount of energy needed to run. “This is more efficient and better for power consumption because the torque from the motors is applied straight to the tires. It’s more efficient than having a rear motor that must transfer torque to both rear tires. Also, you’re taking advantage of all four tires in terms of producing grip, while you can only rely on the back tires in a rear-wheel-drive car,” Zhou says.
Zhou adds that Motorsports wants to help prepare students for the electric vehicle industry. “A large majority of upperclassmen on the team have worked, or are working, at Tesla or Rivian.”
Former Motorsports powertrain lead Levi Gershon ’23, SM ’24 recently founded CRABI Robotics — a fully autonomous marine robotic system designed to conduct in-transit cleaning of marine vessels by removing biofouling, increasing vessels’ fuel efficiency.
An Indigenous approach to sustainable rockets
First Nations Launch, the all-Indigenous student rocket team, recently won the Grand Prize in the 2024 NASA First Nations Launch High-Power Rocket Competition. Using Indigenous methodologies, this team considers the environment in the materials and methods they employ.
“The environmental impact is always something that we consider when we’re making design decisions and operational decisions. We’ve thought about things like biodegradable composites and parachutes,” says rising junior Hailey Polson, team captain. “Aerospace has been a very wasteful industry in the past. There are huge leaps and bounds being made with forward progress in regard to reusable rockets, which is definitely lowering the environmental impact.”
Collecting climate change data with autonomous boats
Arcturus, the recent first-place winner in design at the 16th Annual RoboBoat Competition, is developing autonomous surface vehicles that can greatly aid in marine research. “The ocean is one of our greatest resources to combat climate change; thus, the accessibility of data will help scientists understand climate patterns and predict future trends. This can help people learn how to prepare for potential disasters and how to reduce each of our carbon footprints,” says Arcturus captain and rising junior Amy Shi.
“We are hoping to expand our outreach efforts to incorporate more sustainability-related programs. This can include more interactions with local students to introduce them to how engineering can make a positive impact in the climate space or other similar programs,” Shi says.
Shi emphasizes that hope is a crucial force in the battle against climate change. “There are great steps being taken every day to combat this seemingly impending doom we call the climate crisis. It’s important to not give up hope, because this hope is what’s driving the leaps and bounds of innovation happening in the climate community. The mainstream media mostly reports on the negatives, but the truth is there is a lot of positive climate news every day. Being more intentional about where you seek your climate news can really help subside this feeling of doom about our planet.”
