The last time the world was at +4C was the mid-miocene, 16 million years ago. Sea levels were 40 meters higher than today. The climate was so wet that grasslands grew in what is now desert. Gigantic mammals roamed everywhere. Human ancestors were still living in trees. Antarctica had coastal forests and was home to the only glaciers on earth.
