I was going to do a little more with this, but it is getting stale, and I am not the one to be arguing the various merits of the case.
As I have noted in the past, climate change is one of the favorite scenarios for left leaning preppers (though they don't call themselves that) and almost unnoticed by the libertarian-right prepper groups. IMO this is primarily a cultural-political divide, not one based on the merits of the case.
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):
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.
