Thermal anomalies at the poles are a clear sign of disruptions in the climate system due to fossil fuel emissions.  The recent event raises the concern to alarm level, as thermal anomalies have so far been recorded in the Arctic, but not in Antarctica, and never at both poles at the same time.  

The consequence of destabilising the climate in the polar areas could be a domino effect of global changes leading to abrupt climate change, as these areas play a critical role in regulating the global climate system, as well as sea level. Our climate models do not have the capacity to anticipate points of no return that could trigger a domino effect of global change, but these signals clearly warn of the proximity of such tipping points in the climate system.

This is not good news, particularly in a context where the energy transition is also threatened by the war in Eastern Europe.
