In a continental scale study, researchers used over three decades of Landsat remote sensing data to map and track vegetation changes in the Alaskan and Canadian Arctic regions. 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 direct climate change impact on vegetation in the high latitudes".

 

Plants are very sensitive to their environment so they are excellent predictors of changes in temperature, rainfall,  and atmospheric chemistry. Expect the Arctic to become ever greener.
