...What Reid and President Obama can claim is an achievement that has eluded Democratic Presidents and lawmakers going back more than a half century. "The much-pilloried Harry Reid led an increasingly undemocratic and dysfunctional institution to a stunning victory for the majority party," the Brookings Institution's Tom Mann wrote in Politico. "He deserves an apology from any number of prominent Washingtonians." But if there's one thing Harry Reid has been in Washington long enough to know, it is this: He shouldn't hold his breath waiting...
According to PSU's Mann, that statistical "trick" that Jones refers to in one e-mail - which has been trumpeted by skeptics - simply referred to the replacing of proxy temperature data from tree rings in recent years with more accurate data from air temperatures. It's an analytical technique that has been openly discussed in scientific journals for over a decade - hardly the stuff of conspiracy...
Perhaps most damningly, in an e-mail from 1999, Jones refers to one of Mann's studies from the prominent journal Nature in a discussion of his own data: "I've just completed Mike's Nature trick of adding in the real temps to each series for the last 20 years (i.e. from 1981 onwards) and from 1961 for Keith's to hide the decline." (By the "decline," Jones is presumably referring to the fact that temperature data reconstructed from tree-ring density - a common way to estimate global temperatures before the widespread use of the thermometer - diverges somewhat from...
Many skeptics argue that the case for man-made global warming has been essentially undone, and that before the world goes any further in considering action to control greenhouse-gas emissions, all scientific evidence for warming must be reevaluated. Jones' e-mail about Mann's "trick" appears to indicate that climate researchers have been actively manipulating scientific data to better fit their models on climate change, while other e-mails seemingly confirm what skeptics had long suspected - that the globe in recent years wasn't warming as fast as theories on climate change had assumed. Most of all, the tone...
...Mann and Jones' apparent effort to punish the journal Climate Research, the paper that ignited his indignation is a 2003 study that turned out to be underwritten by the American Petroleum Institute. Eventually half the editorial board of the journal quit in protest. And even if CRU's climate data turns out to have some holes, the group is only one of four major agencies, including NASA, that contribute temperature data to major climate models - and CRU's data largely matches up with the others...
