The Earth’s present-day atmosphere has a carbon concentration that’s 50 percent higher than it was before industrialization, a rapid escalation that is a contributing factor to widespread climate changes, according to experts across the field of paleoclimatology. To further understand the potential effects of climate change and other important aspect of Earth’s climate history, Dana Royer, George I. Seney Professor of Geology in the Department of Earth and Environmental Sciences, and over 80 other paleoclimatologists published a comprehensive charting of 66 million years of atmospheric CO2 data. Their seven-year effort, dubbed the Cenozoic Carbon Dioxide Proxy Integration Project (CenCO2PIP), was…
