A stroll along the coast of Antarctica was once as pleasant as a walk on a California beach, reports Yale News.
Researchers at Yale University and the California Institute of Technology looked at temperature data from the time after the extinction of the dinosaurs: the Eocene Era, about 40-50 million years ago.
By measuring the amount of rare isotopes found in fossils, they found parts of Antarctica averaged 57 degrees, and could get as warm as 63 degrees. Thatâ€™s similar to the average annual temperature off the coast of California today.
