The global warmers seem to believe that the natural state of earth surface temperatures is stability, so that IF it can be shown that 2007 is warmer (or colder) than 1807 that we have a crisis on our hands, a) caused by us and b) subject to our control if c) we place political power in their hands.
In fact, any perusal of the temperature record, at any point in the last 450kY, would predict exactly what is observed, i.e., that 2007 is different than 1807 and 1907.
What's the problem?
The Holocene has been an interglacial with an abnormally stable warm climate.
