Summary:
Recently projected climate changes could have widespread effects on wildlife species. These effects might be positive or negative, depending on the species. Some effects might include extinction, range shifts, mismatches in phenology (timing of pollination, flowering, etc.), and population changes. Effects of climate change on wildlife have been reported for some species and populations in localized areas. Many scientists contend that climate change acts in concert with other variables (such as habitat) to affect species. If the effects of climate change are widespread, there is uncertainty on how wildlife will adapt. Some suggest that evolution and migration will enable species to adapt, whereas others contend that adaptation will be minimal because of limited habitat, and changes in climate that may occur more rapidly than adaptation can respond.
