'AGW? I refute it THUS!': Central England Temperatures 1659 to 2009

The first characteristic of the graph to note is the green trend line. That line indicates an overall warming of 0.26°C per century rate since 1659. So, for some 350 years central England, and the world, have been warming. No big surprise there since Earth has been continuously warming since the end of the Little Ice Age; and, at the end of that 350 year trend line of warming is the first decade of the 21st century.

The second characteristic of the graph is that temperatures just seem to have this habit of going up and down, for extended periods. What’s really amazing is that they did this consistently before the large increase of human CO2 emissions, pre-1946. Okay, maybe that’s not so amazing since this is called temperature variability and represents the natural, dynamic nature of our climate….That variability, as displayed by the CET data in the graph, has experienced temperature changes as much as 2.5°C from one year to the next. A change of 2.5°C in a single year! Keep that figure in mind as we further analyze the dataset. Please note, the graph also reveals very similar temperature variability post-1946, after the huge atmospheric input of human CO2 emissions.

The information here seems at odds with the theory that CO2 levels are effecting the temperatures.
