The ocean is a critical piece of the climate change puzzle. It's estimated that the ocean has absorbed about one third of the excess CO2 humans have added to the atmosphere and more than 90% of trapped heat in the atmosphere. So, today, we’re going underwater to talk about the ocean and climate change with renowned oceanographer Dr. Sylvia Earle. For a deeper dive and additional resources related...

At MIT, we have a commitment to sharing what we know about climate change. That’s why, this summer, we’ll be back soon with a fourth season of TILclimate, bringing you new episodes that dive into even more climate topics, like the role the ocean plays in our climate, solutions for reducing transportation emissions, the future of hydrogen energy, and a whole lot more. All around 10-15 minutes, with...

Today’s episode is about the money of climate change. When people talk about how much it costs to stop climate change, what are we paying for? And who’s paying, exactly? And if we don’t pay to stop climate change – how much will that cost us? To answer these questions, we spoke with Dr. Barbara Buchner from the Climate Policy Initiative. For a deeper dive and additional resources related to this e...

Today we bring climate change to the dining room table. In this episode, we reinvited Dr. Cynthia Rosenzweig onto the TILclimate podcast to tell us just a little more about the connections between the food we eat and climate change. For a deeper dive and additional resources related to this episode, visit: https://climate.mit.edu/podcasts/til-about-what-I-eat For more episodes of TILclimate by the...

Over the last fifty years, our world has made remarkable progress in reducing hunger around the world. How can we keep our farms and food system resilient in a warming climate? Dr. Cynthia Rosenzweig , Senior Research Scientist at the NASA Goddard Institute for Space Studies, joins host Laur Hesse Fisher on this episode of TILclimate to explain how climate change is already impacting our global fo...

In our last episode, we talked about using technology to suck out extra carbon dioxide from the atmosphere. But you might also be thinking—don’t trees do that? Yeah, they do! In fact, some people have proposed that by planting enough trees, we could make a big dent on climate change. In this episode of TILclimate, Massachusetts Institute of Technology professor Charles Harvey helps us answer the q...

We’ve had people ask us, if climate change is caused by adding too much CO2 into the atmosphere, can’t we just suck it back out? Won’t that solve our climate change problem? In this episode of TILclimate (Today I Learned: Climate), Professor Niall Mac Dowell of Imperial College London joins host Laur Hesse Fisher to demystify the process and feasibility of removing CO2 from the atmosphere. For a d...

Is climate change really a national security issue, in the same way we think about terrorism or nuclear weapons? And if so, what are our governments doing about it? In this episode of TILclimate (Today I Learned: Climate), national security expert Alice C. Hill joins host Laur Hesse Fisher to help answer these questions. For a deeper dive and additional resources related to this episode, visit: ht...

Sea level rise is already happening and affecting people right now. We invited Prof. James Renwick back to TILclimate to talk about the near future: what will sea-level rise look like for coastal areas in the next 20 or 30 years, and what can we do about it? For a deeper dive and additional resources related to this episode, visit: https://climate.mit.edu/podcasts/til-about-sea-level-rise-part-2 F...

If you’ve heard only one thing about climate change, it might be that sea levels are rising, and many of the Earth’s islands and coastlines are at risk. But, why? In this episode of TILclimate (Today I Learned: Climate), Professor James Renwick of Victoria University of Wellington in New Zealand joins host Laur Hesse Fisher to break down the science of sea level rise and what’s in store for the fu...

Surveys show that both left- and right-leaning Americans support policies that slow climate change. So why aren’t we seeing more of these policies pass as legislation? In this episode of TILclimate (Today I Learned: Climate), MIT alum Parrish Bergquist joins host Laur Hesse Fisher to explain the significance of public opinion and climate change: what people believe, what influences their opinion a...

Climate change can be confusing, and there’s so much to know. That’s why we’re back with a third season of TILclimate, bringing you new episodes that explain the basics, like why exactly is sea level rising, how climate change affects our national security, how can soils and trees be part of the solution, and so much more. All with real scientists and experts who can give you the straight story, i...

Is it too late to prevent climate change? Are the scary predictions that we hear about inevitable? In this episode of TILclimate (Today I Learned Climate), MIT Prof. Noelle Selin joins host Laur Hesse Fisher to answer these questions. They explore what change is predictable, explain what climate goals like 1.5 C mean, and give insight to what it will take in order to achieve them. Prof. Noelle Sel...

Technologies like solar panels and batteries help us slow down climate change, but they’re not inherently perfect. In this episode of TILclimate (Today I Learned Climate), Suzanne Greene of the MIT Center for Transportation and Logistics and the MIT Environmental Solutions Initiative sits down with host Laur Hesse Fisher to help us navigate how to massively scale up clean tech while making a consc...

Let’s talk about a technology that could change our whole energy system, but so far hasn’t generated a single watt. In the season finale of TILclimate (Today I Learned Climate), Professor Dennis Whyte sits down with host Laur Hesse Fisher to talk about fusion energy. Dennis Whyte is the Director of the MIT Plasma Science and Fusion Center (PSFC), and a Hitachi America Professor of Engineering. As...

This season, we’ve talked about alternative energy sources that don’t emit carbon dioxide -- but what if there was a way to continue using fossil fuels for energy without emitting CO2 into the atmosphere? In this episode of TILclimate (Today I Learned Climate), Dr. Howard Herzog and Professor Brad Hager sit down with host Laur Hesse Fisher to talk about capturing, using, and storing carbon emissio...

We know how to generate tons of electricity without pumping greenhouse gases in the atmosphere, using a technology that’s already mature, widespread, and competitive with fossil fuels -- and also, very controversial: nuclear power. In this episode of TILclimate (Today I Learned Climate), Prof. Jacopo Buongiorno, Director of the MIT Center for Advanced Nuclear Energy Systems, sits down with host La...

We hear a lot about technologies that produce carbon-free energy, but what about actually using less energy to begin with? In this episode of TILclimate (Today I Learned Climate), Harvey Michaels, lecturer at the MIT Sloan School of Management, joins host Laur Hesse Fisher to explore the three ways that energy efficiency can help us reduce carbon emissions. Harvey Michaels, an MIT alumnus now lect...

What will it take to generate the electricity our society needs, without generating carbon emissions? In this episode of TILclimate (Today I Learned Climate), Dr. Magdalena Klemun at the MIT Institute for Data, Systems and Society joins host Laur Hesse Fisher to begin exploring this question, starting with wind and solar power. What exactly are wind and solar power? What challenges do we currently...

In this mini-episode of TILclimate (Today I Learned: Climate), host Laur Hesse Fisher breaks down what we’re actually talking about when we use the word “energy”. In a few minutes, we cover the difference between energy and electricity, and the big picture strategy for how to reduce CO2 for each. Season two of TILclimate focuses on our global energy system, its relationship to climate change, and...

Fossil fuels -- coal, natural gas, and oil -- provide the large majority of our power in the United States and around the world. In this episode of TILclimate (Today I Learned: Climate), John Reilly of the MIT Sloan School of Management joins host Laur Hesse Fisher to demystify fossil fuels: what are the different kinds of fossil fuels, and how do they compare to each other? What is “fracking” and...

The electric grid are networks that carry electricity from central power plants to our homes. But how exactly is electricity generated and brought to our door? And what needs to change if we’re going to transition to generating “clean” electricity? In this episode of TILclimate (Today I Learned: Climate), Harvey Michaels, lecturer at the MIT Sloan School of Management, joins host Laur Hesse Fisher...
