Even more devastating to wildlife will be the global climate change resulting from failure to reduce greenhouse gas emissions. Extensive areas of habitat may be lost to global warming and many species may be unable to shift their ranges fast enough to keep up with global warming. Rare and isolated populations of species in fragmented habitats or those bounded by large water bodies, human habitation and agriculture are particularly at risk, as are montane and arctic species. Leading Democratic Party liberals, such as House Minority Leader Gebhart, oppose the unpopular provision to drill in ANWR, but support other key features of the Bush-Cheney energy plan. As labor unions, such as the United Automobile Workers, have joined with their employers in opposition to increased fuel emission standards, pressure is mounting on Democratic Party politicians to accept the administration's energy plan.
People can adjust to higher prices for gasoline and electricity.
There is little space left for wildlife to make any further accommodations to humans. National Wildlife Refuge welcomes hunters. Within the United States, the most heavily influenced states were usually in the western and south-central sections of the country. These results indicate that global warming has the potential to radically affect the long-term persistence of terrestrial species. Both vegetation models indicated that required migration rates under global warming were ten times higher than the rapid rates observed during the most recent glacial retreat.
