A new report released today says leading scientists confirm global warming has begun, is "very likely" caused by man, and will be unstoppable for centuries. Global Warming Man-Made, Will Continue
Climate Scientists Say Global Warming Is 'Unequivocal,' and Its Cause Is Man-Made

PARIS - International scientists and officials hailed a report Friday saying that global warming is "very likely" caused by man, and that hotter temperatures and rises in sea level "would continue for centuries" no matter how much humans control their pollution.
The head of the Intergovernmental Panel on Climate Change, Rajendra Pachauri, called it a "very impressive document that goes several steps beyond previous research."
A top U.S. government scientist, Susan Solomon, said "there can be no question that the increase in greenhouse gases are dominated by human activities."
The 21-page summary of the panel's findings released Friday represents the most authoritative science on global warming. The panel comprises hundreds of scientists and representatives of 113 governments.
The scientists said the changes are "very likely" caused by human activity, a phrase that translates to a more than 90 percent certainty that global warming is caused by man's burning of fossil fuels. That was the strongest conclusion to date, making it nearly impossible to say natural forces are to blame.
The report said no matter how much civilization slows or reduces its greenhouse gas emissions, global warming and sea level rise will continue on for centuries.
"This is just not something you can stop. We're just going to have to live with it," co-author Kevin Trenberth, director of climate analysis for the National Center for Atmospheric Research in Boulder, Colo., told ...full text
