Global warming could trigger the extinction of half the world's plant and animal species—although humans will probably survive, according to a new British study of the likely effects of climate change. Researchers studied links between mass extinctions and climate changes over 520 million years. In one event, 95% of animal and plant species were eliminated, reports the Guardian.
"Our results provide the first clear evidence that global climate may explain substantial variation in the fossil record," said a population ecologist on the research team. "If our results hold for current warming, they suggest that extinctions will increase."
