May 14 2008 - WASHINGTON, May 14 (Reuters) - Human-generated climate change made flowers bloom sooner and autumn leaves fall later, turned some polar bears into cannibals and some birds into early breeders, a vast global study reported on Wednesday.

Hundreds of previous studies have noted these specific changes and most suggested a link to so-called anthropogenic global warming, but a new analysis published in the journal Nature correlated these earlier studies with changes in temperature, the study's lead author said.
There was a close relationship between temperature shifts between 1970 and 2004 and changes in plants, animals and the physical world, such as the retreat of glaciers and the water level in desert lakes, the study found. More >>>
