&#62; you look at the '30 year bands' he's chosen they are cherry picked.<p>Even if it's true, that's the standard that the mainstream  climate scientists have set for this debate - look at hundred of tree ring records, pick just those that support the narrative; use thermometer readings up until the 1990s, but when they start to show a temperature decline switch to satellite data and drop the thermometers; use data from weather stations that are surrounded by black-top and waste heat exchangers (building air conditioners), and - when challenged - deal with the GIGO problem by merely AVERAGING the bogus heat increase into surrounding weather stations.
