Tipping Points

In recent years, interest in evaluating risks associated with crossing individual and / or compound tipping points within the Earth system in the presence of anthropogenic warming has significantly increased. Such tipping points include both reversible and irreversible changes in high-latitude permafrost, Atlantic meridional overturning circulation, Greenland and Antarctic ice sheets, and boreal and tropical forests, just to list a few. In this tag-team CGD Exchange presentation, we will provide an update on our related efforts, including some preliminary results from our simulations, and discuss our broader involvements.
