Current warm temperatures and high greenhouse gas conditions are reminiscent of the warm Pliocene Epoch that lasted from 5.3 million to 2.6 million years ago. "Early and middle Pliocene global temperatures and greenhouse gas concentrations are probably the closest analog in Earth´s history to the present climate on this planet and the climate conditions we will encounter before the end of this century," says Claus-Dieter Hillenbrand, a sedimentologist at the British Antarctic Survey in Cambridge, U.K., who was not involved in the study. |
