A few weeks ago, Greenland experienced rare rainfall. This changed suddenly when the remnants of tropical storm Larry made it all the to Greenland, triggering “copious” snowfall [1].
(From [1])
It is unusual for tropical storms to come all the way north to Greenland, so this makes the summer of ’21 even weirder. Extreme melting followed by extreme amounts of stow for this time of year.
No one knows yet whether the hurricane induced snow fully balanced out the rain induced melting for this summer. In any case, even a large hurricane isn’t going to reverse the continuing melt off of Greenland’s ice cap.
Models indicate that climate change is driving both warmer air over Greenland and longer lasting hurricanes. So we can expect even more weirdness up Greenland way.
