Sea Temperatures Less Sensitive to CO2 13 Million Years Ago
June 6, 2012
In the modern global climate, higher levels of carbon dioxide (CO2) in the atmosphere are associated with rising ocean temperatures. But the seas were not always so sensitive to this CO2 "forcing," according to a new report. Around 5 to 13 million years ago, oceans were warmer than they are today--even though atmospheric CO2 concentrations were considerably lower.
