Dave Porter is a Lamont polar research scientist who studies the way the ocean and the atmosphere interact with ice sheets in Greenland and Antarctica: "On Earth Day, I hope people remember that climate change is inherently a human problem and that we have only one planet."
This Earth Month, we are celebrating our Earth Institute and Lamont-Doherty Earth Observatory scientists and experts and the 50th anniversary of Earth Day on April 22, 2020.
