Scientist Beloved by Climate Deniers Pulls Rug Out from Their Argument

You don't have to be a Berkeley PhD to see that Muller's data (black line) tracks pretty well with the three established data sets. This is just an initial sampling of Muller's data—just 2 percent of the 1.6 billion records he's working with—but these early findings are incredibly consistent with the previous findings. In his testimony, Muller made these points (emphasis mine):

The Berkeley Earth Surface Temperature project was created to make the best possible estimate of global temperature change using as complete a record of measurements as possible and by applying novel methods for the estimation and elimination of systematic biases.

We see a global warming trend that is very similar to that previously reported by the other groups.

The world temperature data has sufficient integrity to be used to determine global temperature trends.

Despite potential biases in the data, methods of analysis can be used to reduce bias effects well enough to enable us to measure long-term Earth temperature changes. Data integrity is adequate. Based on our initial work at Berkeley Earth, I believe that some of the most worrisome biases are less of a problem than I had previously thought.

For the many climate deniers who hang their arguments on Muller's "doubts," this is a severe blow. Of course, when the hard scientific truths are inconvenient, climate denying House leaders can always call a lawyer, a marketing professor, and an economist into the scientific hearing.
