Tony Heller On US Temperatures
Tony Heller made the following mashup of two graphs intended to show that NASA lies about CONUS temperatures as part of a criminal conspiracy to fabricate global warming. It will be very easy to show that Tony Heller is the one lying. It took about 5 minutes for me to document why the bottom graph is an improvement over the top graph, and there's nothing "inexplicable" about it. The information needed to explain the changes comes a page on NASA's website that documents the developments and improvements to the GHCN station dataset over time. NASA isn't hiding anything.

Areas with missing data were filled in, meaning that the area-we...
