Do you have any idea HOW scientists have concluded that humans have played a role in the warming observed over the last 150 years? Before you decide whether or not they can actually do that, you need to learn what it is they're actually doing. It is most assuredly not based on "faith".The climate can warm. Or it can get colder or it can change. I deny none of any part of those things.
What I deny (up to a point) is the notion that scientists can validly deduce that human-kind plays much of a role in any of that. It’s the “A” in “AGW” that is suspect.
When the AGW FAITH BASED cadre speaks about anyone who deviates in any way from swallowing their orthodox beliefs, they falsely label them “Deniers.” The question is: Deniers of what?
I’m more of a skeptic. But I will accept the term “denier” for a little bit. Absent better evidence and non-fudged data, I’ll deny your claims about the role of a tiny bit more of a very trace amount of CO2 in our atmosphere as constituting a greenhouse gas caused catastrophe. Especially when it is conjoined with demands for some world wide socialist new order and one world government.
