So you dont have a model that shows temperature rising since 1998. And I was pulling for you to win the nobel in 2013.
Take a guess at what would happen to your chart above if instead of using the average temp from 1900-99 we used the average temp for 1950-99 or 1910-2010 or 1912-2012. That is right, the hot areas would flatten out and the cold areas would look more extreme.
