Global Warming's Impacts on Animals
Many animals are already feeling the effects of global warming and many more are threatened.
Polar Bears
Global warming has already had a significant effect on the southern-most polar bear populations at western Hudson Bay, Canada. Researchers there have noted that polar bears are 10% thinner and have 10% fewer cubs than 20 years ago (Stirling et al. 1999). The culprit, earlier breakup of sea ice, due to warmer temperatures.

Gray Wolves
Complex interactions in Isle Royale National Park in
Michigan have led to larger wolf packs, reduced moose populations
and uninhibited growth in balsam trees, choking out other plants and
changing the balance of nature.

Trout and Salmon
As air temperatures continue to climb, water temperatures will also rise in lakes and streams, and fish such as trout and salmon, which are temperature-sensitive, will begin to lose important habitat.
