Hi, I recently read a paper titled "
Climate Change, Humans, and the Extinction
of the Woolly Mammoth ". In this paper, the authors simulated paleoclimate with GENESIS 2 GCM for
126 ky BP, 42 ky BP, 30 ky BP, 21 ky BP, and 6 ky BP. I want to adapt this method to simulate paleoclimate for my research, so I checked the original paper of the method and merely understood. Is there any practical tutorials, software or R packages could work this out?
