Climate and Ice during the Last Interglacial
Read more of: Climate and Ice during the Last InterglacialThis project studies the last Interglacial (129-116 thousand years ago, ka) when CO2 and global temperature were both higher than they were before human industrialisation. By examining Last Interglacial climate, we can gain insights into climate processes and feedbacks close to those expected by the end of the 21st century.
