Reporting by John Van Radowitz on the greening of Greenland:
Today only four indigenous tree species grow on the large island, confined to small areas in the south. Three-quarters of Greenland, the world’s most sparsely populated country, is covered by a barren ice sheet.
But by the year 2100 swathes of verdant forest could be covering much of its land surface. “Greenland has…the potential to become a lot greener,” Professor Jens-Christian Svenning, from Aarhus University in Denmark, said. “Forest like the coastal coniferous forests in Alaska and western Canada will be able to thrive in fairly large parts of Greenland… with trees like sitka spruce and lodgepole pine. It will provide new opportunities for the Greenlanders.”
Research showed that with expected levels of warming, a majority of 44 species of North American and European trees and bushes will be able to thrive in Greenland.
The transformation is likely to alter Greenland’s ecosystem, leading to the loss of Arctic animals and plants. On the other hand there could be significant commercial possibilities linked to forestry, agriculture and tourism.

We don’t know… aren’t “commercial opportunities” a big part of what has us in this mess in the first place? In any event, we’re keeping a close eye on this, as well as environs nearer to our home in Arctic Alaska.
