On August 16, 2022, President Joe Biden signed into law the Inflation Reduction Act (IRA). It was the largest of three bills signed over the course of 10 months that together make up the United States’ largest investment in addressing climate change… well, ever. Dr...

On October 5, TILclimate is returning for our fifth season! If you're looking to get smart quick on climate change – without the jargon and without the politicking – this podcast is for you! In each episode, we work with experts at MIT and beyond to explain climate change science and solutions in fifteen minutes or less.

We were going to produce an episode on El Niño, and its relationship to climate change. And then we found out that Outside/In, from New Hampshire Public Radio, already did that. And they did a really good job.

You probably know that today’s climate change is caused by certain gases—what scientists call greenhouse gases—that human activity has been adding to our atmosphere. But—how do these gases actually keep heat from escaping into space? And why these gases in particular?

Carbon dioxide—CO2—is the greenhouse gas you’ve probably heard most about, on this podcast and elsewhere. But it turns out, methane is an incredibly important greenhouse gas too.

Refrigerants are in every refrigerator, freezer and air conditioner, and the world is on track to make a lot more of them in the years to come. They’re also powerful greenhouse gases: often thousands of times more warming than carbon dioxide.

Today we’re talking about desalination: turning saltwater into freshwater, so we can drink it or use it to grow crops. And we’re talking about this because, in many parts of the world, freshwater is getting harder to come by. So… is converting saltwater a good solution?

If you live in the U.S. Mountain West, the Pacific Coast of the Americas, or large parts of Australia or southern Europe, there’s a good chance a major wildfire has passed near you in the last five or six years—maybe one more intense than anything you’ve ever heard of in your area. But why exactly are wildfires getting worse? Is climate change entirely to blame? And what should we be preparing for next?

We all want to live full, healthy lives. But climate change is threatening a growing number of people’s lives and well-being. So we’ve invited a guest on the show to help us see climate change not in tons of carbon dioxide, but as a matter of health.

The large majority of new energy we’re building today comes from clean, renewable wind and solar projects. But to keep building wind and solar at this pace, we need energy storage: technologies that save energy when the weather is favorable, and use it when wind and sun are scarce.
