What's wrong with using tree ring data to created a climate record? The CRU researchers assumed that a tree grows faster when it's warmer. But rainfall has a stronger influence on tree growth than temperature does. Temperature is coorelated to tree growth only in the sense that it tends to rain more in warm eras. Critics call the CRU's approach the "tree-o-meter" theory.<ref>"[http://tomnelson.blogspot.jp/2012/02/email-3826-feb-2001-in-email-copied-to.html Email 3826, Feb 2001]," Tom Nelson, Feb. 04, 2012. "In one go, they tossed aside dozens of studies which confirmed the existence of the MWE [Medieval Warm Era] and LIA [Little Ice Age] as global events, and all on the basis of tree rings - a proxy which has all the deficiencies I have stated above."</ref>

In another Climategate email, Jones enthusiastically demands that the IPCC review process be rigged: "I can't see either of these papers being in the next IPCC report. Kevin and I will keep them out somehow - even if we have to redefine what the peer-review literature is!" Jones also admitted that the reason he claims the Earth is warming is political: "The scientific community would come down on me in no uncertain terms if I said the world had cooled from 1998. Okay it has but it is only seven years of data and it isn't statistically significant."<ref name=steyn14>Steyn, Mark, "[http://www.steynonline.com/2697/how-the-science-got-settled How the Science Got Settled]", December 6, 2014.</ref> Jones is ignoring the fact that 1998 was an unusually warm year due to an El Niño event. All the same, it's clear that he runs the CRU to produce made-to-order results rather than as a scientist.
