There are (at least) two camps in the global warming skeptics camp
No, there's at least five.
1. those who deny it is happening
As you say. But there's hardly any of those.
2. Those who deny it's unprecedented.
That the remains of 11th C. Viking settlements in Greenland have beech trees frozen in their permafrost is an example of the kind of evidence that people in this camp find compelling.
3. Those who deny the "anthropogenic" part but agree that recent decades are at least unusual, because of the sun or cosmic rays or ocean currents or whatever.
4. those like me who know it's happening but don't think it's worth changing our entire civilization
Indeed, under any even remotely plausible set of assumptions adaption to warmth is a far superior idea to going back to the hunter-gatherer societies which are the only ones carbon neutral.
5. Those of us who think that even if you take all the worst alarmist propaganda at face value, global warming is a FANTASTIC idea and we should be doing EVERYTHING WE CAN to speed it on its way!
Logic here being, I believe the worst possible generally accepted scenario is AGW topping out at around 6C up from now and about 1.4 billion deaths. Bad, that, you think?
Well, from geology we know that ever since C02 dropped below 500 ppm we've been having these Ice Age thingys, and we're pretty much at the peak temperature for recorded interglacials, and their depths are -- coincidentally enough -- just about 6C colder than now. And the estimates of the total human population worldwide that could feed themselves in a full on Ice Age vary wildly, but I haven't seen an estimate over 600 million and they go as low as 20 million. Either way, we're talking seven billion plus people dead at the very least.
The alternative that through AGW we shift that curve up so that world temperatures cycle between 6C warmer than now to current temperatures; hey, that sounds awesome! Let's DO IT!
