Greenland ice sheet melted at unprecedented rate during July

We know the warming of the Arctic is proceeding apace, but this only occasionally makes the “news” (aka the daily petty hysteria).  So here is a clear image of a relatively dramatic finding (because it happened over only four days).  There are more dramatic findings, but they developed over years so they don’t trigger our “leopard threat” primate alarms.

The Greenland ice sheet on July 8, left, and four days later on the right. In the image, the areas classified as ‘probable melt’ (light pink) correspond to those sites where at least one satellite detected surface melting. The areas classified as ‘melt’ (dark pink) correspond to sites where two or three satellites detected surface melting. Photograph: Nasa
