    Max Cunningham, a graduate student at Lamont-Doherty, traveled to Costa Rica’s Mount Chirripó this past summer to test the idea that mountain glaciers carved the summit we see today. He and his colleagues hope to eventually pin down when Chirripó’s high-elevation valleys eroded into their current form. Check out a recap of their 2014 field…

Recent record-breaking heat waves have affected communities across the world. The Extreme Heat Workshop will bring together researchers and practitioners to advance the state of knowledge, identify community needs, and develop a framework for evaluating risks with a focus on climate justice.
