Key messages

Past research has shown that multiple climate subsystems might undergo abrupt shifts, such as the Arctic Winter sea ice or the Amazon rainforest, but there are large uncertainties regarding their timing and spatial extent.

The ClimTip project’s latest webinar will showcase investigations regarding when and where abrupt shifts occur in the latest generation of Earth system models (CMIP6) under a scenario of 1% annual increase in CO2. Systems analysed include the North Atlantic subpolar gyre, Tibetan Plateau, land permafrost, Amazon rainforest, Antarctic sea ice, monsoon systems, Arctic summer sea ice, Arctic winter sea ice and Barents sea ice. Except for the monsoon systems, abrupt shifts were found in all of these across multiple models.

This webinar will outline the detection and analysis methods used in the study.
