Major Atlantic ocean current system might be approaching critical threshold
05/08/2021 - The major Atlantic ocean current, to which also the Gulf stream belongs, may have been losing stability in the course of the last century. This is shown in a new study published in Nature Climate Change. The Atlantic Meridional Overturning Circulation, or AMOC, transports warm water masses from the tropics northward at the ocean surface and cold water southward at the ocean bottom, which is most relevant for the relatively mild temperatures in Europe. Further, it influences weather systems worldwide. A potential collapse of this ocean current system could therefore have severe consequences.

Parts of Greenland may be on the verge of tipping: new early-warning signals detected
05/18/2021 - Scientists have detected new early-warning signals indicating that the central-western part of the Greenland Ice Sheet may undergo a critical transition relatively soon. Because of rising temperatures, a new study by researchers from Germany and Norway shows, the destabilization of the ice sheet has begun and the process of melting may escalate already at limited warming levels. A tipping of the ice sheet would substantially increase long-term global sea level rise.

Niklas Boers awarded with EGU Outstanding Early Career Scientist Award
10/26/2020 - One of 2021’s Outstanding Early Career Scientist Awards goes to PIK researcher Niklas Boers. Awarded by the European Geosciences Union (EGU), the prize recognizes Boers’ important contributions in the fields covered by the Nonlinear Processes in Geosciences (NP) Division, which is focused on a series of nonlinear paradigms including deterministic chaos, tipping points, predictability and its limits, as well as extreme events.
