If the world’s greenhouse gas emissions are left unchecked, the Earth’s climate will be similar to how it was 50 million years ago by 2150. This period, known as the Eocene, was characterized by an ice-free Earth and an arid climate across most of the planet. This is the conclusion of new research published by UW–Madison researchers in Proceedings of the National Academy of Sciences that used leading climate models and archaeological data to compare Earth’s future with its past.
