It is not possible to know everything about everything, and to research and validate every possible topic that comes up. Even if the human brain had the capacity to do all this, I can't imagine why anyone would want to. You learn about the stuff that is compelling and interests you, not the other stuff.

Sorry scientists, none of you have presented a case compelling enough to make me want to research on my own whether the world is warming or cooling, and the significance of that (is it a normal cycle or are humans the cause of it?) I'm not going to jump on the bandwagon one way or the other at this point. I'm pretty neutral until I start hearing more concrete cause/effect/outcome/significance from you experts. What you're presenting now comes off as more political than scientific to me, and I despise politics.
