Scientists and actuaries deal in the same stuff: probability. Never certainty. However, ALL the world's major scientific academies, and 98% of the world's climatologists, agree that it's almost certain that we have caused this warming, and that it will grow much worse. Exactly how much worse is open to debate.<quoted text>
It's not "settled science" until the Academy of Sciences can report without using terms such as "much" and "very likely." Neither are very scientific.
It will be settled science once they can state that "XX percent of this warming has been conclusively proven as due to human activities"
After all it is man-caused global warming that we're worried about, right?
I wish it were otherwise.
