Nature Climate Change, August 10 The Arctic Ocean could be seasonally ice-free at temperatures only slightly above today’s, once land-based Arctic summer temperatures average 4 to 5°C above pre-industrial. This would occur by summer 2035 under high emissions scenarios; parts of the Arctic were already far warmer this summer. These new simulations using CMIP6, by […]
Nature Geoscience, August 3 An updated approach is required to estimate the melting of global glaciers due to rock debris partially insulating the glaciers’ surface. As glaciers shrink, eroded rock from surrounding mountain slopes becomes exposed and slides down, forming a layer on the surface of glaciers which, if thick enough, reduces the rate at […]
