Fun question: Is there irrefutable proof by every scientist that global warming is occuring and is directly caused by man made by-products?

Is there irrefutable proof by every scientist about anything? There are scientists who insist evolution didn't occur. There are scientists who insist that tobacco doesn't cause lung cancer. There are scientists who insist that certain races/cultures are inferior than others.

Of all the weak arguments you have made, that is the weakest. Pure piffle. You let your contempt for Gore influence your ability to reason.
