Everything seems to be "sooner than expected" or "faster than predicted". This is some crazy stuff, yah, man.
"BEIJING, March 12 (Xinhuanet) -- Forests of spruce trees are invading the Arctic tundra because of global warming and evicting and endangering species that live there quicker than scientists thought, a new study was quoted as saying Monday by news reports.
"The conventional thinking on treeline dynamics has been that advances are very slow because conditions are so harsh at these high latitudes and altitudes," said Ryan Danby of the University of Alberta. "But what our data indicates is that there was an upslope surge of trees in response to warmer temperatures. It's like it waited until conditions were right and then it decided to get up and run, not just walk."
While in many places the idea of more trees is a good one, this Arctic takeover endangers species like caribou and sheep that thrive in the tundra, as well as the native people who depend on these species for their survival."
