Paleoclimate researchers find connection between carbon cycles, climate trends

Making predictions about climate variability often means looking to the past to find trends. Now paleoclimate researchers have found clues in exposed bedrock alongside an Alabama highway that could help forecast climate variability. In their study, the researchers verified evidence suggesting carbon dioxide decreased significantly at the end of the Ordovician Period, 450 million years ago, preceding an ice age and eventual mass extinction. These results will help climatologists better predict future environmental changes.
