The article points out that as the temperature continues to climb, the suitable habitat for brook trout will diminish with less than 100 years before brook trout can only be found in the highest mountain streams.
From the story:
The national nonprofit Natural Resources Defense Council and Defenders of Wildlife spotlighted the problem in a 2002 report "Effects of Global Warming on Trout and Salmon in U.S. Streams." Using weather projections from the United Nations' Intergovernmental Panel on Climate Change, they estimated that upward of 40 percent or more of rivers and streams now suitable for cold-water fish will become too warm to sustain them by 2090.
Federal projections are even worse. A New England Regional Climate Variability and Change Assessment done for the U.S. Global Change Research Program says if the Earth's greenhouse-gas levels double because of fossil-fuel burning and other emissions, "the region faces a 50- to 100-percent potential loss of habitat for brown, brook, and rainbow trout."

It's enlightening, entertaining and flat out scary.
