Space technologist Robbie Schingler cofounded a satellite company that images the whole planet every day, making visible changes on Earth. He shows how pairing that data with AI creates a "planetary intelligence" we can use to spot emerging threats we might not have seen otherwise. Now he asks: Can we close the gap between seeing a crisis coming and actually stopping it?

Liana Finck’s cartoons explore life’s big predicaments: what to make for dinner, how to leave a party without being rude, how to feel like more than a snack machine once you have a child. In today’s episode, Liana shares how drawing has become a practice for her to answer questions, solve problems, and why creating art helps humans understand ourselves better. Liana also discusses why she’s not bothered by impostor syndrome (okay maybe it helps that she regularly contributes to The New Yorker) and how she navigates the feelings of doubt we all experience with honesty and humor.

We're living through oil wars, wildfire smoke and extreme weather driven by a warming planet. But environmentalist Bill McKibben says one thing is finally going right: the price of clean energy has plunged, making it cheaper than ever to power the world without burning fossil fuels. He breaks down how energy from the sun became the best option on Earth — and why this narrow window of time may be our last real shot at a different future. "Energy from heaven, not from hell," he says.

(Following his talk, Elise Hu interviews McKibben on why the climate sector needs to stop calling affordable solutions as “alternative energy” and why he thinks recent wars have sped up the clean energy shift. They also discuss what cheap solar means for the balance of power around the world, his work to get plug-in solar legislation passed in the U.S., and why it’s more important now than ever before to have good neighbors today.)

She explores why the public's trust in science is wavering — and the importance of winning it back. In this conversation with TED’s Whitney Pennington Rodgers, Rivera maps out what it takes to become a trusted messenger in an era when expertise itself is up for debate.
