It is the passion and emotional investment that betrays their dishonesty. They don't want to debate and don't want to hear opposing views. Their ideology tells them AGW should be true, therefore the matter is settled.
Like medicine (Obamacare), politics should not influence science.
LOL! The pro agw crowd never wants to hear the facts because “the science is settled”. Kind of like a 3 day old buritto settling in your gut. Ends up a load of crap.
