Heat sinking, temperatures rising in the US of A

By request, I'm closing a previous discussion, which turned into a discussion of the siting of weather stations among other things, and opening up this new thread for a continuation. The other thread was getting way to hard to load and it was almost impossible to follow the discussion.

To help kick off, if you want to repeat your latest comments from the old thread here, feel free to do so. 

Addendum: (I've added the following as a comment.)

If anyone is new to the reason for Evan's work, this article from ClimateProgress, together with Andy Revkin's piece and an article by Jeff Masters of Wunderground are as good as any. The comments at Climate Progress are useful as well.

And then there is this article, too, in which Anthony Watts more clearly explains his mindset.
