In the first half of our two-parter on data centers and the U.S. energy system, we dug into the challenges that these huge, concentrated electricity users pose for communities and power grids. In this second installment, Prof. Costa Samaras of Carnegie Mellon University and Dr. Vijay Gadepally of MIT return to talk through some of the options on the table for responding to these challenges. And we explore how our choices fit into the bigger picture of tackling climate change, as data centers’ growing electricity needs meet those of electric vehicles, heat pumps and clean manufacturing.

At the heart of the explosion in artificial intelligence, there are data centers. Companies are pouring money into these facilities to train and run AI models—and with this massive buildout comes a remarkable appetite for electricity. In the first installment of our two-parter on data centers and the U.S. energy system, Prof. Costa Samaras of Carnegie Mellon University and Dr. Vijay Gadepally of MIT walk us through some of the challenges posed by this surging electricity demand. And they discuss why our response to this moment matters for power grids and people right now, and for the long-term work of tackling climate change.

How can climate change cause both more intense droughts and more severe floods? With help from Prof. Mathew Barlow, we dive into the water cycle on a warming planet, and learn how the basic physics of water moving through the atmosphere can explain a lot of the strange weather we need to prepare for as the world heats up.

In our previous episode, we spoke with Dr. Sarah Das, a Scientist Emeritus at Woods Hole Oceanographic Institution, about how climate change is affecting the big polar ice sheets of Antarctica and Greenland. She’s been traveling to the poles for her research since the nineties, and this week, she’s taking us behind the scenes: into the world of glacier science, “boomerang flights,” and ice as far as the eye can see.

The frozen parts of our planet—from sprawling polar ice sheets and floating sea ice to mountain glaciers and frigid soils—face profound risks from climate change. Already, a warmer world has transformed these landscapes, with consequences that span the globe. Dr. Sarah Das, a Scientist Emeritus at Woods Hole Oceanographic Institution, joins to discuss her decades-long career studying the Antarctic and Greenland ice sheets and help us understand how changes to the polar regions affect people now and in the future.

From cars and ships to bridges and skyscrapers, steel forms the landscape of modern life. At the same time, steelmaking is one of the world’s biggest industrial sources of climate-warming carbon dioxide. Antoine Allanore, a professor of metallurgy at MIT, explains how CO2 became so entrenched in the chemistry of steelmaking—and the creative ways scientists and engineers are trying to get it out.
We gratefully acknowledge Katie Daehn, postdoctoral associate, and Matthew Michalek, Ph.D. student and research assistant, of the Allanore Group for additional assistance and participation in this episode.

Solutions to climate change, like building clean energy, come with a price tag. But unchecked warming also brings serious costs. As we make investments to rein in our climate pollution, how should we weigh costs and benefits? Dr. Jennifer Morris of MIT joins the show to explain how economists have tried to pin down the dollar costs of a warming planet, and why a clear answer has proved elusive. Together, we’ll ask how the tools of economics can help us plan for a better, more prosperous future, even in the face of uncertainty.

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.

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’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.

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.

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.

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.

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.

A new type of climate science is allowing us to draw clearer connections between our warming planet, and the extreme weather events this warming creates. Thanks to “climate change attribution,” scientists can now say confidently when climate change has made a heatwave or hurricane more likely, and by how much. Dr. Andrew Pershing explains how attribution science works, and why this information is useful for understanding and adapting to a warming world.

The Earth has gone through massive climate change before—many times over, in fact!—but human civilization has not. Prof. David McGee, a specialist in the study of ancient climates, joins the show to explain what came before the 10,000 years of global stability in which complex human societies emerged and grew. Along the way, we explore the scientific tools used to study the distant past, the great cycles of the ice ages, and what it can all tell us about the climate change we’re experiencing today.

Just 20 years ago, hydrogen cars and battery electric cars were pretty evenly matched as clean alternatives to gas-powered vehicles. But today, batteries are way ahead: the big car companies are rapidly electrifying their lineups, while only a few hydrogen cars are available. What happened?
