From the Netherlands, Dr. Thomas Crowther speaks for a team of 50 world scientists all warning the official climate projections are missing an important carbon feed-back, one that’s as large as all U.S. emissions: the warming soil. As we warm, the soil will release carbon dioxide and methane equivalent to the greenhouse gas emissions of the United States.
From Maine, paleobiologist Dr. Jacquelyn Gill says abrupt climate change hit species before us. We’re next. In this program, we’ll talk about how creatures fell into extinction during abrupt climate shifts, sometimes within a single human lifetime. Paeloecologist Jaquelyn Gill joins us.
