This is the logic of deniers (sorry, "sceptics"):
First premise: If AGW is true, then "we must give unlimited power and unlimited funds to the climate change hysteria profiteers in government, academia and business" and "we also have to drastically downscale our lifestyles."
Second premise: We don't want to do those things.
Conclusion: Therefore, AGW is a hoax and we shouldn't take it seriously.

Now, if you'll excuse me, I'm off in my black helicopter to David Suzuki's private landing strip, where I'll board his taxpayer-funded Learjet and fly with him to a lavish seven-day party on Tahiti with assorted supermodels, rockstars, IPCC scientists, and French-speaking lesbian UN officials, presided over by Al Gore, where -- when we're sober enough to talk -- we will plot how to establish a world socialist government, take away your guns, force better health care on you, and make you memorize long passages from books by Naomi Klein.

It's a tough job, but someone's gotta do it.
