#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.

Brown-affiliated studies help explain overestimations in impact of Greenland Ice Sheet melting
Two studies noted that current measurements and simulations may not adequately consider processes that retain meltwater.

Did meltwater from circum-Arctic ice sheets trigger AMOC weakenings during past deglaciations? We think that we can present a convincing line of evidence, from the central Arctic to the North Atlantic. See our recent paper in QSR:
