Eugene Domack, the Joel W. Johnson Family Professor of Environmental Studies, was the guest speaker at the October meeting of the Central New York Association of Professional Geologists (CNYAPG) in Syracuse, N.Y.
In “400 parts per Million of CO2, and Why Earth History Matters,” Domack said the atmosphere has surpassed 400 parts per million of carbon dioxide – a level that has not been experienced in more than 25 million years – and a benchmark by which to evaluate the sensitivity of the earth to climate change. He discussed how studying the planet’s past can lead to a better understanding of the new climate crisis.
