Here’s a handy scale to locate your position on the agw topic:

In the realm of climate science, as in most topics, there exists a range of ideas as to what is going on, and what it means for the future. At the risk of generalizing, the gamut looks something like this:

Ultra-alarmists think that human greenhouse-gas-producing activities will vastly change the face of the planet and make the earth inhospitable for humans; they therefore demand large and immediate action to curtail greenhouse gas emissions.

Alarmists understand that human activities are changing the earth’s climate and think that the potential changes are sufficient to warrant some pre-emptive action to try to mitigate them.

Skeptics think that humans activities are changing the earth’s climate but, by and large, they think that the changes are not likely to be terribly disruptive (and even could be, in net, positive) and that drastic action to curtail greenhouse gas emissions is unnecessary, difficult, and ineffective.

Ultra-skeptics think that human greenhouse gas-producing activities are impacting the earth’s climate in no way whatsoever.

Most of my energy tends to be directed at countering alarmist claims about impending climate catastrophe, but the scientist in me gets just as bent out of shape about some of the contentions made by the ultra-skeptics, which are simply unsupported by virtually any scientific evidence. Primary among these claims is that human activities are not responsible for the observed build-up of atmospheric carbon dioxide. This is just plain wrong.http://masterresource.org
