The consensus of US citizens that GW is not a big priority to them isn't an indication that they are right about having properly evaluated the situation. As George Carlin said, “Think of how stupid the average person is, and realize half of them are stupider than that.”
The hockey stick is fairly indisputable, though it is a condensed graph which narrows down to just a few degrees, making the spike look larger than if it were relative to absolute temperature. It should be easy to concede that relatively rapid changes in environment are more difficult to adapt to.
That said, there must be an appropriate course of action somewhere between the extremes of do nothing, and kill yourself.
