Gen Z and younger millennials are the most climate literate generations the world has ever seen. They learned about climate change in school; now, it's part of how they plan for the future, including for jobs, housing ... and kids.

So, what do experts say about how to navigate the kid question? In this installment of Nature Quest, Short Wave speaks to climate journalist Alessandra Ram about the future she sees for her newborn daughter. Plus, how do we raise the next generation in a way that's good for the planet?

Resources discussed in this episode include:
Jade Sasser's book, Climate Anxiety and the Kid Question
Kimberly Nicholas's High Impact Climate Action Guide
Elizabeth Bechard's book, Parenting in a Changing Climate
The Climate Mental Health Network's Climate Emotions Wheel

Google, Microsoft and Meta have all pledged to reach at least net-zero carbon emissions by 2030. Amazon set their net-zero deadline for 2040. To understand how these four tech companies could possibly meet their climate goals amid an artificial intelligence renaissance, Short Wave co-host Emily Kwong discusses the green AI movement. Speaking with scientists, CEOs and tech insiders, she explores three possible pathways: nuclear energy, small language models (SLMs) and back-to-the-future ways of keeping data centers cool.

By 2028, Lawrence Berkeley National Laboratory forecasts that U.S. data centers could use as much as 12% of the nation's electricity. The reason: generative AI. Since 2022, AI innovation by four leading tech companies — Google, Microsoft, Meta and Amazon — has led to annual increases in both energy and water consumption. So, in this episode, Short Wave co-host Emily Kwong probes huge water footprint of AI. We begin with the rise of data centers, then look at how computers came to need so much water and, finally, what tech companies are doing to try to turn the ship around.

P.S. Part 2 talks about the leading solutions in the green AI movement. So don't miss our Friday episode!
