Phys Org: Faster Arctic warming hastens 2-degree-Celsius rise by eight years, finds modeling study

November 14, 2023 — 

The study does not attempt to quantify the ways in which Arctic warming affects the rest of the world, for instance through the retreat of sea ice that helps to keep the planet cool, but instead estimates the direct contribution of Arctic warming to global temperature increases.

Co-author Professor Julienne Stroeve (UCL Earth Sciences, the University of Manitoba, Canada, and the U.S. National Snow and Ice Data Center), said, “While our study focuses on how Arctic warming affects global temperature change, the local impacts should not be overlooked. A 2 C temperature rise globally would result in a 4 C annual mean rise in the Arctic, and a 7 C rise in winter, with profound consequences for local people and ecosystems.
