The way we grow and distribute food today is deeply dependent on fossil fuels, yet that dependence can feel invisible. Sustainable food systems researcher Prof. Jennifer Clapp joins the show to walk us through all the ways fossil fuels are used to produce one simple food item: a tortilla chip. Along the way, we’ll explore the hard work being done to eliminate climate pollution from the food we eat.

The landmark Paris Agreement of 2015 gave the world a shared target for halting climate change: that global warming should stop well short of 2 degrees Celsius. But how did that target come about, and what exactly does it mean? Prof. Maria Ivanova, a specialist in international environmental policy, shares with us the history and diplomacy behind those crucial 2 degrees.

The Earth naturally absorbs some of our climate pollution from burning fossil fuels. But how much, and how fast? Geophysicist Prof. Daniel Rothman joins the podcast to explain the nature and scale of the natural carbon cycle, and how our appetite for fossil fuels has pushed it out of balance.

Today, companies are storing millions of tons of carbon dioxide underground every year to prevent this climate pollution from warming the planet. In the future it might be billions of tons. But is it dangerous to pump so much liquefied carbon below our feet? Geologist and carbon storage expert Prof. Bradford Hager joins the podcast to explain the risks and how to avoid them.

What if there was a way to continue using fossil fuels for energy without emitting CO2 into the atmosphere? To prepare for a new listener question about carbon capture, we're re-airing this season two episode in which Dr. Howard Herzog and Professor Brad Hager talk about capturing, using, and storing carbon emissions, and how it fits into a clean energy future.

Is hydrogen fuel a climate solution? That depends on how you produce it. Dr. Emre Gençer of the MIT Energy Initiative takes us on a tour of the hydrogen spectrum, from climate-polluting “gray” hydrogen made from natural gas to the much more promising “green” hydrogen made with renewable electricity.

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? Sergey Paltsev, senior research scientist at the MIT Energy Initiative, helps TILclimate answer this listener question.

Hydrogen gas acts like a fossil fuel, but with no carbon emissions. Is it the silver bullet we’ve been waiting for? To prepare for some new listener questions about hydrogen energy, we're re-airing this season four episode in which Prof. Svetlana Ikonnikova of the Technical University of Munich explains how hydrogen works and its potential in the energy transition.

Wind power is the largest source of clean, renewable energy in the United States. But the large turbines that create that power can endanger wildlife. MIT Professor Michael Howland returns to the podcast to answer a listener's question about the risks of wind energy to birds—and explain how wind turbines compare to coal plants, power lines, office towers, housecats, and other threats to birdlife in the modern world.

You might have heard how wind turbines failed in Texas during a terrible cold front in 2021. Does this mean we can’t rely on this clean, renewable source of energy when the weather turns extreme? MIT Professor Michael Howland joins the podcast to explain how wind turbine operators prepare for frigid conditions, and why some turbines failed in Texas while others are working fine in Antarctica.
