Greenland’s Ice Is Getting Darker, Increasing Risk of Melting

Via Lamont-Doherty Earth Observatory:

‘Greenland’s snowy surfaces have been getting darker over the past two decades, absorbing more heat from the sun and increasing snow melt, a new study of satellite data shows. That trend is likely to continue, with the surface’s reflectivity, or albedo, decreasing by as much as 10 percent by the end of the century, the study says.

While soot blowing in from wildfires contributes to the problem, it hasn’t been driving the change, the study finds. The real culprits are two feedback loops created by the melting itself. One of those processes isn’t visible to the human eye, but it is having a profound effect.’ (Thanks, Seth).

So essentially, melting begets more melting, as if we shouldn’t have known that already.
