Antarctica is getting greener

Antarctica may be the world’s frostiest place, but a mossy outgrowth along the northern peninsula is making the continent look a bit greener, The Washington Post reports. The moss itself isn’t new, but it is certainly taking advantage of a warming planet. Every winter the moss freezes solid, with new layers grow atop old ones each summer. By studying those well-preserved layers from the past 150 years, researchers discovered that the moss is now growing more than 3 millimeters a year, compared with a previously slower pace of less than a single millimeter a year, the scientists report in Current Biology. If greenhouse gas emissions continue to rise, the mossy peninsula could someday become forested, as in the Cretaceous period, when Tyrannosaurus rex ruled Earth.
