We hear that the air is getting warming, glaciers are melting, sea levels are rising, and carbon dioxide levels are climbing, all at alarming rates, but from our point of view on Earth, shifts in climate seem to happen at a snail's pace.
To help us visualize what some of these changes will mean in more tangible terms, researchers at Lawrence Berkeley National Laboratory in California have made interactive maps to show how current climates on the planet will march from one area to another as global temperatures rise. Among one of the team's more troubling finds was that the planet's boreal forests, which suck up and store a huge chunk of the world's terrestrial carbon, will shift, not expand toward the poles.
By the end of the century, a forest near Alberta, Canada, for example, will inherit a climate that's currently 100 miles to the south, the researchers say. This also means the forest will need to move 100 miles north to keep up with its climate. "Forests can't adapt this quickly, however, meaning that in the short-term they'll be stressed. And in the long-term they'll be forced to move north and give up their southern regions to grassland," reads a press release from the lab.
