Politics & Pseudo-Science
I agree with all the negative criticisms made here so far. I believe what we have here is some major bias coming from Sperling's Best Places (a source of the "data analysis"), its owner Fast Forward Inc., and that company's president Bert Sperling. Where are all three located? Why, of course in Portland, Oregon, on the west coast. I'm sure it's not all Sperling et al., that others influencing or even controlling them are behind it as well. Are we surprised that the west coast is all green? This pretends to be scientific, but it is not. It is partially pseudo-scientific, but mostly politics. You can see this right away where the three individual tornado, hurricane and earthquake maps have scientific references, but the main map is sourced with Sperling, a social website and company.
