World Scientists: No Doubt Global Warming is Man Made

The evidence is overwhelming:

The world's leading climate scientists, in their most powerful language ever used on the issue, said global warming is "very likely" man-made, according to a new report obtained Friday by The Associated Press.

The report provides what may be cold comfort in slightly reduced projections on rising temperatures and sea levels by the year 2100. But it is tempered by a flat pronouncement that global warming is essentially a runaway train that cannot be stopped for centuries.

Who are these people:

The report by a group of hundreds of scientists and representatives of 113 governments contains the most authoritative science on the issue. It was due for official release later Friday morning in Paris.
