‘A very different and frightening world’ Parmesan and others have been predicting such changes for years, but even she was surprised to find evidence that it’s already happening; she figured it would be another decade away.
Just five years ago biologists, though not complacent, figured the harmful biological effects of global warming were much farther down the road, said Douglas Futuyma, professor of ecology and evolution at the State University of New York in Stony Brook.
“I feel as though we are staring crisis in the face,” Futuyma said. “It’s not just down the road somewhere. It is just hurtling toward us. Anyone who is 10 years old right now is going to be facing a very different and frightening world by the time that they are 50 or 60.”
While over the past several years studies have shown problems with certain species, animal populations or geographic areas, Parmesan’s is the first comprehensive analysis showing the big picture of global-warming induced changes, said Chris Thomas, a professor of conservation biology at the University of York in England.
While it’s impossible to prove conclusively that the changes are the result of global warming, the evidence is so strong and other supportable explanations are lacking, Thomas said, so it is “statistically virtually impossible that these are just chance observations.”
