Taking Earth’s temperature Feb 26, 2026

Show notes

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.

The nuclear price tag Feb 12, 2026

Show notes

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.

Marshes, mangroves, meadows Jan 29, 2026

Show notes

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. Thanks as well to the Waquoit Bay National Estuarine Research Reserve and research coordinator Megan Tyrrell.

New season, new name! Jan 22, 2026

Show notes

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! Find us on Instagram, TikTok, and YouTube @askmitclimate for outtakes, bonus content, and more climate knowledge from MIT. And we love hearing from our listeners; email us at askmitclimate@mit.edu.

Update: Where we've been and where we're going Nov 04, 2025

Show notes

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.

Transmission: Power to the people Jul 10, 2025

Show notes

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.

Cleaner air Jun 12, 2025

Show notes

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.

Dealing with dead batteries May 29, 2025

Show notes

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.

Geothermal: Earth’s infinite clean power Apr 17, 2025

Show notes

Deep beneath the Earth’s surface, a molten stew of metals radiates vast amounts of energy. Prof. Roland Horne, Director of the Stanford Geothermal Program, joins TILclimate to talk about the “geothermal energy” technologies that tap this underground resource for electricity, manufacturing, and home heating and cooling. He also shares the recent breakthroughs that have begun bringing this always-on, clean, renewable source of energy to new places and applications.

The great indoors Apr 03, 2025

Show notes

Modern buildings are complex machines, using heating, cooling and a host of other appliances to turn energy into comfort. But that energy comes with a cost: today, our buildings do more to warm the climate than heavy industry, agriculture, or transportation. Prof. Tarek Rakha provides an architect’s view of buildings and the climate, sharing how we can build anew—and upgrade our existing buildings—to use less energy, lower our living costs, benefit the climate, and live more comfortably, all at the same time.
