Ask MIT Climate

Here at TILclimate (Today I Learned: Climate), there’s one question we get from our listeners more than any other: “What can I do to make a difference on climate change?” In this special episode of the podcast, three guests who have made acting on climate a big part of their lives join interim host Aaron Krol to share their stories and their advice for those who want to do more. Together, we discu...

When talking about climate change solutions, we often hear about reducing emissions and adapting to climate impacts, but a third option is starting to get more attention: altering the atmosphere. In this episode of TILclimate (Today I Learned: Climate), MIT alumnus Janos Pasztor joins host Laur Hesse Fisher to explain geoengineering: what it is and the different technologies that are being researc...

What exactly is a carbon price, and how does it work? What would it look like and how would it change everyday life? In this episode of TILclimate (Today I Learned: Climate), MIT economics professor Christopher Knittel joins host Laur Hesse Fisher to break down the complexities of carbon pricing. Together, they explain different types of programs, give us a sense of how much it would cost, and exp...

With climate change, some parts of the world will get more water, but others will experience droughts. Some will start seeing more mosquitoes, but some fewer. And some regions might actually benefit economically. What’s the deal? In this episode of TILclimate (Today I Learned: Climate), MIT professor Elfatih Eltahir joins host Laur Hesse Fisher to talk about how climate impacts will differ across...

How do we make choices in the face of uncertainty? In this episode of TILclimate (Today I Learned: Climate), MIT professor Kerry Emanuel joins host Laur Hesse Fisher to talk about climate risk. Together, they break down why the climate system is so hard to predict, what exactly scientists mean when they talk about “uncertainty”, and how scientists quantify and assess the risks associated with clim...

Scientists predict that hurricanes will hit us harder in the future — but why? And what can we expect to see? In this episode of #TILclimate (Today I Learned: Climate), MIT professor Kerry Emanuel joins host Laur Hesse Fisher to break down how these “heat engines” work and how a changing climate will increase hurricane intensity, storm surges, and flooding. They also explore how people around the...

Humans use around 90 billion metric tons of materials every year, creating about ⅓ of total global greenhouse gas emissions. Which materials produce the most emissions? You might be surprised. In this episode of TILclimate (Today I Learned: Climate), MIT professor Elsa Olivetti joins host Laur Hesse Fisher to talk about materials, or as Prof. Olivetti calls it, “the study of stuff”. Prof. Olivetti...

Wrap your head around this: humans have changed clouds. In this episode of TILclimate (Today I Learned: Climate), MIT professor Dan Cziczo joins host Laur Hesse Fisher to spell out why this is, and what this has to do with climate change. They explore how clouds form in the first place, how human activity has impacted cloud formation and rainfall, and what scientists are still trying to understand...

“I love to travel. But I hate the fact that something I love to do, creates so much pollution.” In this episode of TILclimate (Today I Learned: Climate), MIT professor Steven Barrett and host Laur Hesse Fisher dig into how — and why — air travel impacts our earth’s climate, and what solutions are on the horizon. They explore the surprising heating effect of condensation trails (“contrails”), how c...
