Mardi Gras can make a lot of trash, adding up to millions of pounds each year. Now, some parades in New Orleans are cutting down on their environmental footprint by banning plastic beads.

The plant, formally known as Ovicula biradiata, is especially notable for being the simultaneous discovery of a new species and genus. It was found with help from the community science app iNaturalist.

Northeast Michigan held one of the shortest fishing seasons ever — 17 minutes. Hundreds of people gathered and raced against the clock in an effort to catch a lake sturgeon, or "dinosaur" fish.

President Trump's calls for the U.S. to take over Greenland have sparked alarm and outrage.

Denmark, which is responsible for Greenland's security, recently announced that it would further boost its defense spending.

And a recent poll found 85 percent of Greenlanders are opposed to being part of the United States.

Parliamentary candidate Naaja Nathanielsen is one of them.

It isn't clear whether Trump's ambitions for Greenland will take. But some politicians in the territory are taking his calls for acquisition more seriously than ever before.

Firings at the U.S. Forest Service will interrupt land management work that will leave the U.S. more exposed to damaging wildfires, among other impacts, according to employees at the agency.

What happens when a team of scientists and local Awajún guides go on a 38-day trip into the Alto Mayo region of Peru? Over 2000 species are identified, of course! Tucked in this lush landscape where the Amazon basin meets the Andes mountains, were 27 species of animals previously unknown to science. It makes us wonder, what else is out there that the scientific community hasn't seen? And who already knows about it?

Check out photos of all the critters we mentioned — and more!

The reasons for the beachings are unclear. Reasons could include disorientation caused by loud noises, illness, old age, injury, fleeing predators and severe weather.

Courts have ordered the Trump administration to lift its freeze on federal funding, but lots of CLIMATE-related spending is still paused. In Colorado, the freeze has hit affected many projects.

Students at Lewis & Clark College in Oregon are trying to bring more attention to one of the world's smaller and often overlooked plants with this year's seventh annual Moss Appreciation Week. (This story first aired on Morning Edition on February 14, 2025.)

In Colorado, the federal funding freeze has hit projects from a brownfield cleanup in Pueblo to "once in a lifetime" funding for solar projects in Native communities.

Moss Appreciation Week is packed with events both scientific... and also silly. Moss walks, moss talks, moss movies, crafting moss-themed Valentines, and a "gastropod derby" with snails and slugs (for whom moss is a nice moist microclimate).

A recent drought in Panama was so severe that the canal had to reduce traffic. How is climate change impacting Panama -- and how does that ripple out to the global economy?

Giving a bouquet of flowers to your beloved is a classic Valentine's Day gesture of love. But as we hear from our correspondent in Colombia, growing those flowers comes at a steep environmental cost.

Panama has been looking for solutions to a long-term problem. Every time a ship passes through the Panama Canal, more than 50 million gallons of fresh water from Lake Gatun pour out into the ocean.

Nobody ever thought Panama could run out of water. It is one of the rainiest countries in the world. But a couple years ago, a drought got so bad that the canal had to reduce traffic by more than a third - which had a huge impact on global shipping.

The Panama Canal needs more water. Authorities have decided to get it by building a dam in a spot that would displace more than 2,000 people along the Rio Indio.
