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.

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.
