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.For a deeper dive and additional resources related to this episode, visit: For more episodes of TILclimate by the MIT Environmental Solutions Initiative, visit tilclimate.mit.edu. CreditsLaur Hesse Fisher, Host and Executive ProducerDavid Lishansky, Editor and ProducerAaron Krol, Writer and ProducerAndrew Moseman, Science ReporterMichelle Harris, Fact CheckerMusic by Blue Dot SessionsArtwork by Aaron Krol

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.For a deeper dive and additional resources related to this episode, visit: For more episodes of TILclimate by the MIT Environmental Solutions Initiative, visit tilclimate.mit.edu. CreditsLaur Hesse Fisher, Host and Executive ProducerDavid Lishansky, Editor and ProducerAaron Krol, Writer and ProducerLindsay Fendt, Science ReporterMichelle Harris, Fact CheckerMusic by Blue Dot SessionsArtwork by Aaron Krol

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.For a deeper dive and additional resources related to this episode, visit: For more episodes of TILclimate by the MIT Environmental Solutions Initiative, visit tilclimate.mit.edu. CreditsLaur Hesse Fisher, Host and Executive ProducerDavid Lishansky, Editor and ProducerAaron Krol, Writer and ProducerMichelle Harris, Fact CheckerMusic by Blue Dot SessionsArtwork by Aaron Krol
