Michael Mann has stepped into a methane-emitting cowpile. Mann is the Penn State climatologist famous for inventing the "hockey stick" graph promoting the notion that planetary temperatures spiked in the 20th century after a Golden Age of stasis. This graph was misleading at a minimum, the product of what Phil Jones, director of the Climate Research Unit of East Anglia termed "Mike's Nature trick" to "hide the decline." What Mann did was splice two separate data sets together to create the illusion of spiking temperatures; the graph spliced data sets together without differentiation, hiding the global temperature "decline" shown by the Briffa reconstruction set. Mann would use a number of statistical tricks to do away with the Medieval Warming Period, an embarrassment to the warm-mongers. He would hide data that disagreed with a sudden spike in temperature. Mann was the lead author of the IPCC Third Assessment... (Read Full Article)
