Algae are turning Greenland green and thats a problem for sea-level rise

Thanks to global warming, algae are expanding on Greenland, helping to slowly melt the massive island's ice sheet and turning it "green."

The microscopic algae that grow on the Greenland ice sheet are dark, which means they absorb more sunlight and warm up the surface more quickly than white ice, which reflects light.

"More algae means a darker surface, and darker surfaces melt faster," said Martyn Tranter, head of the British research project Black and Bloom, the first group to study the phenomenon.

As this feedback loop continues, the extra warming from increased algae coverage causes a more rapid melting of the ice sheet. That's a problem because if all the ice on Greenland melted, sea levels would rise by as much as 20 feet in spots worldwide, inundating coastal cities.

In other news, we still have an illegitimate president and a government of Russian puppets, traitors, nutjobs and other miscreants to deal with.
