Why on Earth do you think that the distance from nominal surface temperatures to 
freezing much less absolute 0 is the right scale to compare global warming 
changes against? You need to compare against the size of global mean temperature 
changes that would cause large amounts of human suffering, and that scale is on 
the order of a *few* degrees, not hundreds. A change of half a degree over a few 
decades with no signs of slowing down *should* be alarming.
