WASHINGTON - Greenhouse gases are known to spur global warming, but scientists said on Monday that global warming in turn spurs greenhouse gas emissions -- which means Earth could get hotter faster than climate models predict.


Two scientific teams, one in Europe and another in California, reached the same basic conclusion: when Earth has warmed up in the past, due to the sun's natural cycles, more greenhouse gases have been spewed into the atmosphere.
As greenhouse gas levels rose, so did Earth's temperature, the scientists reported.

Earth has not endlessly warmed up, though, because these natural solar cycles ended, letting the planet cool down and prompting a corresponding drop in greenhouse gas emissions, the scientists reported.

It means the warming is happening faster, each decade is actually warming faster than it would have," Torn said in a telephone interview. "It's the pace of change that will be one of the big problems. It's how humans adapt and the cost that will depend on the rate of change of climate

The European team estimated that global warming in the next century may be 15 percent to 78 percent higher than current estimates because these predictions fail to take into account the feedback mechanism involving carbon dioxide emissions

WHOAH what a could be 15-78% thats a pretty wide spread there???
