This map is from Hansen’s 2001 paper, which has been deleted from the NASA web site.
It shows that US rural stations cooled -.05C from 1900 to 1999, and that urban stations were 0.31C warmer. The obvious conclusion being that the US is cooling, and needs to be cooled further to account for UHI.
So what does NASA and NOAA do? They adjust the other direction – by about 0.8C, to create a fake warming trend.
