Climate
change is considered more of a reality now, with eight of the ten
warmest years ever recorded having occurred during the 1990s. This
warming trend is predicted to continue with global temperatures
rising about 1.0 degree Celsius by the middle of the 21st century.
Although climate has changed many times before in the earth's history,
the key concerns with the current change are the speed at which
it is taking place, driven by greenhouse gas emissions.
Ecosystems
that experience changing climate will also face fundamental changes
to wildlife habitats. While each ecosystem will be affected in unique
ways, some common general patterns are predicted. For example, massive
change is expected to reduce the average habitat patch size, resulting
in loss of species diversity. Southern species are expected to move
further north, although their ability to do so may be exceeded by
the pace of climate change and shifting habitats.
Through
its continuing work on Wildlife Habitat Status reports, WHC will
help monitor how the risk
to habitats posed by climate change evolves in the coming years.
