Jason Box arns about the albedo changes in Greenland

Albedo changes on Greenland are also a big worry.
I got this alarming photo from Jason Box, who adds that it's the: "southern tip of Greenland... darkness is outcropping dust and probably more so the effect of the dust acting as fertilizer for ice algae and its dark byproducts. Black carbon from fire is there but not as important as the biological factors. What still may be scary is the high sensitivity of the southern Greenland ice sheet margin to warming air temperature and higher humidity. It's melting fast, mostly due to warming air temperature and higher humidity, more precipitation and more of it falling as rain than snow."
