Three Things You Absolutely Must Know About Climategate

This may seem obscure, but the science involved is being used to justify the diversion of literally trillions of dollars of the world’s wealth in order to reduce greenhouse gas emissions by phasing out fossil fuels. The CRU is the Pentagon of global warming science, and these documents are its Pentagon Papers. Here are three things everyone should know about the Climategate Papers. Links are provided so that the full context of every quote can be seen by anyone interested. First, the scientists discuss manipulating data to get their preferred results. The most prominently featured scientists are paleoclimatologists, who reconstruct historical temperatures and who were responsible for a series of reconstructions that seemed to show a sharp rise in temperatures well above historical variation in recent decades. In 1999, Phil Jones, the head of CRU, wrote to activist scientist Michael “Mike” Mann that he has just “completed Mike’s Nature trick of adding in the real temps … to hide the decline”(0942777075). This refers to a decline in temperatures in recent years revealed by the data he had been reconstructing that conflicted with the observed temperature record. The inconvenient data was therefore hidden under a completely different set of data. Some “trick.” Mann later (2003) announced that “it would be nice to try to ‘contain’ the putative ‘MWP,’ even if we don’t yet have a hemispheric mean reconstruction available that far back” (1054736277). The MWP is the Medieval Warm Period, when temperatures may have been higher than today. Mann’s desire to “contain” this phenomenon even in the absence of any data suggesting that this is possible is a clear indication of a desire to manipulate the science. There are other examples of putting political/presentational considerations before the science throughout the collection...read more
