Since Lewis and Curry 2014 was published the fans of Cowtan and Way's satellite kriging revision to the Hadley Centers HADCRUT4.something is constantly mentioned as a L&C spoiler. C&W does run warmer than the older HADCRUT4.somethingless. I haven't used much of the C&W new and improved version since I like to check regions using the Climate Explorer mask capability. Well, now C&W are on Climate Explorer.
So there is a brief intro to HADCRUT4.something with new and improved smearing. Not meaning to be a cut down of C&W, it serves a purpose, but increase smearing reduces the relationship between temperature and the energy it is supposed to represent. Now if C&W had the "skepticism" required they would compile a "Global" energy anomaly reconstruction which would illustrate just how much error using temperature anomaly for temperature ranges from -80C to 50C can produce. Then they would focus on the "other" forces that effect climate rather than just the CO2 done it all meme. Since Way is Inuit, I am sure he knows about yellow snow and the variety of other than pristine white varieties. It would be nice to see him focusing on the whole picture instead of trying to be a good CO2 band member.
