Ask MIT Climate

Solar panels, batteries, microgrids, and other emerging energy technologies are making it easier than ever before for a community to produce some or all of its own power. Prof. David Hsu lays out the policies and technologies challenging the traditional, centralized model of the electric grid, including in places that lack reliable access to electricity. As the world strives to make energy cleaner, cheaper, and more accessible, what can local models offer that a big utility can’t—and the other way round?

Climate change is putting pressure not only on humans, but also on our fellow species. How can plants, animals, and other living things survive as their habitats are transformed? In this episode, we explore one way: moving. Dr. Toni Lyn Morelli and Dr. Alexej Sirén help us understand how climate change is shaking up the map of where species live—and what that means for all of us who share this planet.

The past three years have been the three hottest humanity has ever measured. But who does the measuring, and how? Dr. Samantha Burgess, of the European Union’s Copernicus Climate Change Service, joins the show to explain how we know the temperature of the Earth, and how a global community of scientists works together to keep tabs on the health of our planet.

Nuclear power offers huge amounts of round-the-clock energy free of climate-warming pollution. In the United States, it’s also become very expensive to build. As government support grows to bring more nuclear power to the U.S., Prof. Jacopo Buongiorno of MIT joins us to break down how nuclear got so costly and what we can learn from countries with more active nuclear industries.

Salt marshes humming with insects and birds. Mangrove forests with tangled, arching roots. Seagrass meadows that blanket the ocean floor. The world’s coastal saltwater wetlands provide shelter for wildlife, purify water, and protect seaside infrastructure. And as Dr. Julie Simpson of MIT tells us, they also have a climate superpower: drawing down and locking away extraordinary amounts of planet-warming carbon dioxide.We gratefully acknowledge Professor Heidi Nepf; Ph.D. student Ernie Lee; and undergraduate student Joyce Yambasu of MIT for additional assistance and participation in this episode.

The eighth season of MIT’s climate change podcast starts next week, and we’ve got some news! TILclimate is now Ask MIT Climate. It’s part of an effort to bring all of our climate change resources under one umbrella and reach learners in as many ways as we can.We’re also diving into video!

We’re dropping into your feed to share the news that our founding host, Laur Hesse Fisher, is departing MIT and TILclimate. In this episode, Laur sits down with new host Madison Goldberg to talk about the philosophies that have shaped TILclimate over seven seasons and take listeners behind the scenes of the show. They also discuss what’s in store for season eight—because TILclimate isn’t going anywhere.Check out an extended video version of this conversation: https://www.youtube.com/watch?v=kB544MVZ9bgFor a deeper dive and additional resources related to this episode, visit: https://climate.mit.edu/podcasts/update-where-weve-been-and-where-were-goingFor more episodes of TILclimate by the MIT Climate Project, visit tilclimate.mit.edu. CreditsLaur Hesse Fisher, Founding Host and Senior EditorMadison Goldberg, Incoming Host and Associate ProducerAaron Krol, Writer and Executive ProducerDavid Lishansky, Editor and ProducerDanielle Simpson, EditorMusic by Blue Dot SessionsArtwork by Aaron KrolSpecial thanks to Brett Paci of MIT OpenCourseWare and to the folks at Giro Studio for their help producing this episode.

Power lines may not look as high-tech and inspiring as a wind turbine or a solar field. But as MIT’s Joshua Hodge explains, these lines—and the rest of the sprawling “machine” that is the transmission system—are critical for harnessing clean, cheap, reliable power. In this episode of TILclimate, we explore what we stand to gain from a bigger, better transmission system, and how we might make it happen.For a deeper dive and additional resources related to this episode, visit: https://climate.mit.edu/podcasts/e8-transmission-power-people.For more episodes of TILclimate by the MIT Climate Project, visit tilclimate.mit.edu. CreditsLaur Hesse Fisher, Host and Senior EditorAaron Krol, Writer and Executive ProducerDavid Lishansky, Editor and ProducerMadison Goldberg, Associate ProducerGrace Sawin, Student Production AssistantMichelle Harris, Fact CheckerMusic by Blue Dot SessionsArtwork by Aaron Krol       

Here at TILclimate, we’re often asked about the health and environmental effects of materials in solar panels and batteries. But what if the greatest costs are the ones we’re already bearing—from the fossil fuels those technologies would replace? In this episode, pulmonologist Dr. Mary Rice explains how air pollution from coal, oil, and gas can make us sick, and why a cleaner energy system benefits both the climate and our health.For a deeper dive and additional resources related to this episode, visit: https://climate.mit.edu/podcasts/e7-cleaner-air.For more episodes of TILclimate by the MIT Climate Project, visit tilclimate.mit.edu. CreditsLaur Hesse Fisher, Host and Senior EditorAaron Krol, Writer and Executive ProducerDavid Lishansky, Editor and ProducerMadison Goldberg, Associate ProducerGrace Sawin, Student Production AssistantMichelle Harris, Fact CheckerMusic by Blue Dot SessionsArtwork by Aaron Krol

The world’s demand for batteries to power electric vehicles is growing at incredible speed. What will we do with all these batteries when they die? Dr. Linda Gaines of Argonne National Laboratory joins TILclimate to explain what batteries are made of, how we obtain those materials, and how we can get them back when the batteries reach the end of their lives—along with other options to make this industry less wasteful and more productive.For a deeper dive and additional resources related to this episode, visit: https://climate.mit.edu/podcasts/e6-dealing-dead-batteriesFor more episodes of TILclimate by the MIT Climate Project, visit tilclimate.mit.edu. CreditsLaur Hesse Fisher, Host and Senior EditorAaron Krol, Writer and Executive ProducerDavid Lishansky, Editor and ProducerMadison Goldberg, Associate ProducerGrace Sawin, Student Production AssistantMichelle Harris, Fact CheckerMusic by Blue Dot SessionsArtwork by Aaron Krol
