I'm saying that it lines up pretty well. In NYC for example, there has been a large population for many years (3.3 million+ in 1900). In Phoenix, not that long ago the population wasn't very much. In 1950, it was only 106,000. Now it is 4.5 million. That is a huge increase in 70 years with tons and tons of development and significant changes in the areas landscape. I think it might play a role with daytime highs as well along with AGW.
