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. That’s similar to the average annual temperature off the coast of California today.
