In a first continental scale study of its kind, researchers used over three decades of Landsat satellite data to map and track vegetation changes in in Alaskan and Canadian Arctic. Covering more than 4 million square miles, 30 percent of the high Arctic showed increases in vegetation coverage (greening) compared to 3 percent showing decreases in coverage (browning). Jeffrey Masek, the lead NASA scientist at the Goddard Space Center commented: "it shows the climate change impact on vegetation in the high latitudes".

 

Plants are very sensitive in environmental changes so they become excellent predictors of changes in temperature, rainfall,  and atmospheric chemistry. Expect the Arctic to become every more green.
