Is global warming irreversible???

Well, if it is, then we shouldn't reduce CO2 emissions....

Climate change is "largely irreversible" for the next 1,000 years even if carbon dioxide (CO2) emissions could be abruptly halted, according to a new study led by the US National Oceanic and Atmospheric Administration (NOAA).

The study's authors said there was "no going back" after the report showed that changes in surface temperature, rainfall and sea level are "largely irreversible for more than 1,000 years after CO2 emissions are completely stopped."

NOAA senior scientist Susan Solomon said the study, published in this week's Proceedings of the National Academy of Sciences journal, showed that current human choices on carbon dioxide emissions are set to "irreversibly change the planet."

I've asked this question for a while - we've been warned for so long about CO2 emissions - and they keep going up - that it's about time we wondered if it is indeed too late to do anything. Of course, being a skeptic, I've never been interested in reducing CO2 - but this is a question for believers...
