"The sensitivity of the clouds to the ship exhaust was measured during the summer season, when most ship traffic occurs." "Contaminated clouds can act like a blanket. They warm the surface more than a pristine cloud. In our case, we found that a polluted cloud may lead to accelerated sea ice melt"

Exceptional snow accumulation in Svalbard this season, combined with unusually mild temperatures, highlights the shift from a cold–dry to a warm–wet Arctic climate regime. Deep loose snow (>1 m) is extremely difficult for snowmobile travel, especially with heavy sleds. #ClimateChange #ArcticResearch

#Refreezing #SurfaceRunoff ❄️👉💧 Current measurements and models often overestimate how much meltwater from Greenland’s ice sheet enters the ocean because they miss key retention processes. Much meltwater refreezes in porous ice or ponds, cutting actual runoff by 9–15% compared to older estimates.
