The past three years have been the three hottest humanity has ever measured. But who does the measuring, and how? Dr. Samantha Burgess, of the European Union’s Copernicus Climate Change Service, joins the show to explain how we know the temperature of the Earth, and how a global community of scientists works together to keep tabs on the health of our planet.

Nuclear power offers huge amounts of round-the-clock energy free of climate-warming pollution. In the United States, it’s also become very expensive to build. As government support grows to bring more nuclear power to the U.S., Prof. Jacopo Buongiorno of MIT joins us to break down how nuclear got so costly and what we can learn from countries with more active nuclear industries.

Salt marshes humming with insects and birds. Mangrove forests with tangled, arching roots. Seagrass meadows that blanket the ocean floor. The world’s coastal saltwater wetlands provide shelter for wildlife, purify water, and protect seaside infrastructure. And as Dr. Julie Simpson of MIT tells us, they also have a climate superpower: drawing down and locking away extraordinary amounts of planet-warming carbon dioxide.
