Patty Kearon: My comment came across in the wrong way. I apologize for the apparent insult. 

What I meant was that the scientific method produces facts, or as close to a fact as can logically be attained. There is overwhelming evidence that the climate is changing/warming; and 2) that anthropogenic causes are mostly to blame.

There's your facts. Now comes the politics. Pro fossil fuel entities scoff or deny (though, documents reveal that Exxon new about the possibility decades ago) as do those distrustful of science in general, an attitude born of ignorance and fear of smart people.

And change. Change is scary. Denial is easy (typically my approach to health problems BTW).

But the facts are there. Just like a thermometer.
