1. The scientific method is not based on consensus, so using an appeal to authority based upon it is a bogus argument - a point of "quite universal" agreement among scientists can still be 100% wrong.
2. One can accept that the scientific consensus about CO2 warming is correct, and yet still argue that climate variation due to natural and/or cyclical causes is a bigger driver in any climate change.
3. One can accept that man-made climate change is real, and still argue that it's more cost-effective to mitigate rather than precipitously impose massive changes in our economies to reduce CO2 emissions; or that the funds would be better used for other purposes (reducing hunger, etc).
see, these are the relevant arguments, I think.
Consensus among all national organizations, including the AAAS and NSA among other international boards, is that CO2 is the leading factor in climate change, and that human contributions are very significant, if not the most significant source.
The debate, as you suggest, really concerns what to do about it. What can we do about it and can we do anything about it? Where should we place our attention and how should we expend our resources? Very relevant questions.
But creating lies that there is no consensus among the people charged with providing this data is ridiculous and frankly, infuriating.
I agree that appeal to authority is it's own fallacy, but I'd rather appeal to the primary source--authority; the mouths of those who produce the data--rather than the talking heads that filter this data through their own uninformed biases and agendas.
Why is one willing to trust Glenn Beck or Rush over the NSA and all other international institutions that remain 100% agreed on the issue?
it makes no fucking sense. Then again, these are the same people willing to exchange their savings for gold.
Rejection of legitimate authority is not somehow more valid than appeal to authority, is it?

I mean, look at the type of ridiculous arguments that the deniars try to make. It's hilarious--call the climate scientists "fear mongerers" while dispensing their own form of distrustful fear-mongering!

oh shit, the horse's mouth. don't expect deniers and those without any climate science, let alone science background to dare come near this stuff.
