Wildfires and how we're changing them
2 november 2023 · 14 min
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? Dr. Daniel Swain joins the TILclimate podcast to help break down what is going on with wildfires and climate change. Lees meer

Can desalination solve water scarcity?
26 oktober 2023 · 14 min
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? Our guest Prof. John Leinhard has devoted his whole career to this question—and its relationship with climate change. Lees meer

How tackling methane cools the planet fast
12 oktober 2023 · 12 min
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. Stopping methane emissions today is a powerful way to dampen climate change in the very near term—to keep the Earth cooler in the next 10 or 20 years. So today, Prof. Desiree Plata returns to TILclimate to tell us—how do we get that done? Lees meer

Wait, how do greenhouse gases actually warm the planet?
5 oktober 2023 · 15 min
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? To help answer these questions, we invited Desiree Plata, an associate professor in the Department of Civil and Environmental Engineering at MIT and the director of the MIT Methane Network. Lees meer

TIL about carbon offsets
17 november 2022 · 14 min
What if you could pay someone else to cancel out your carbon emissions? As countries, organizations, and even individuals around the world commit to lowering their impact on the climate, many have been doing just that. So today, we’re going to look at how “carbon offsets” work and whether they are an effective tool for slowing climate change. For this episode, we sat down with carbon trading and offsets expert Dr. Barbara Haya from the University of California Berkeley. Lees meer
Dr. Barbara Haya is a Research Fellow at the Goldman School of Public Policy at the University of California Berkeley. She leads the Berkeley Carbon Trading Project, which studies the effectiveness of offset programs and carbon trading with the goal of ensuring these programs and policies support effective climate action. Dr. Haya is also helping the University of California to develop its own strategy of using offsets to meet their carbon neutrality goals. Haya received her PhD at UC Berkeley’s Energy and Resources Group, and has previously worked with NGOs to help support international offset program reform.
