Global warming study finds real change in America
WASHINGTON -- From Florida to Alaska and from coast to coast, nature's indicators show strong evidence of global warming in America, scientists said yesterday.
A report co-written by University of Texas biologist Camille Parmesan concluded that more than 40 scientific studies link climate change with observed ecological changes. In half of the studies, the link is strong, the report stated.
Satellite data and a century of temperature records have shown an overall increase in global temperatures to parallel the buildup of heat-trapping greenhouse gases in the atmosphere.
But in a report released by the Pew Center for Global Climate Change, Parmesan and University of Colorado ecologist Hector Galbraith say there is growing and scientific evidence that now shows specific trends in the United States.
'What we were able to show is it's happening in everyone's back yard,' Parmesan said."
