The warmers keep denying that the temperature changes we are experiencing happened in recent times. They deny the Medievil Warming Period, they deny that where we have Alaskan glaciers not, just "recently" there were enormous dense forests, just 3,000 years ago.
They want to keep the public ignorant, and they are doing quite a good job of it. Of course, when Questioned, and faced with absolute evidence, they just say, this time is different, this time we know it is CO2 that is causing the warming. Even though the warming is very, very slight.
And we know they are completely insane, because even if the AGW "theory" is completely true, they actually think that they passing a few laws or putting up a thousands of millions of windmills, that they can actually do something to have man stop emitting CO2. (actually I mean slow down CO2 emissions). They actually believe that by passing laws in the US that somehow they are going to affect world CO2 emissions. that is a completely insane theory. Of course, most of them, just care about the piece of the pie that is theirs by continuing this charade, their kickbacks in so many forms, but there are actually stupid people that think they can actually stop CO2 emissions from rising. I drove 4 hrs yesterday in heavily populated NJ/Pa and didn't see one electric car, but saw thousands of trucks and SUV's. The general population is stupid and easily led, but that only goes so far.

But the projections depend on amplification by positive feedbacks and those feedbacks are independent of the cause of the initial warming. Therefore, if you expect a catastrophe due to feedbacks resulting from GHG warming, then you need to explain why a catastrophe did not arise during earlier Holocene warming. Can you provide such an explanation?
