Adjusting Measurements to Match the Models – Part 1: Surface Air Temperatures

Energy Matters:



In his recent Data Adjustment Bureau post Euan Mearns added a footnote in which he asked for “more examples of climate data being adjusted to make it match the theory.” In previous posts we have addressed a number of such examples individually, and compiling them into a group of posts (there are too many to deal with in just one) struck me as a good idea. So here is Post number 1, which analyzes the adjustments applied to the surface air temperature (SAT) records over the land areas that make up 30% of the Earth’s surface. The conclusions? In previous posts and comments I had said that adjustments had added only about 0.2°C of spurious warming to the global SAT record over the last 100 years or so – not enough to make much difference. But after further review it now appears that they may have added as much as 0.4°C.
