Numerical Model Predicts A Greener Arctic

Rising temperatures will lead to a "greening" of the Arctic by mid-century, according to a new numerical model.  The greening not only will have effects on plant life, the researchers noted, but also on the wildlife that depends on vegetation for cover. The greening could also have a multiplier effect on warming, as dark vegetation absorbs more solar radiation than ice, which reflects sunlight. In the paper, scientists detail their new computer projections stating that wooded areas in the Arctic could increase by as much as 50 percent over the coming decades. The researchers also show that this dramatic greening will accelerate climate warming at a rate greater than previously expected.  read more
