Global warming is having a significant impact on hundreds of plant and animal species around the world -- although the most dramatic effects may not be felt for decades, according to a new study in the journal Nature.
"Birds are laying eggs earlier than usual, plants are flowering earlier and mammals are breaking hibernation sooner," said Terry L. Root, a senior fellow with Stanford's Institute for International Studies (IIS) and lead author of the Jan. 2 Nature study.
"Clearly, if such ecological changes are now being detected when the globe has warmed by an estimated average of only 1 degree F (0.6 C) over the past 100 years, then many more far-reaching effects on species and ecosystems will probably occur by 2100, when temperatures could increase as much as 11 F (6 C)," Root concluded.
