The UN's about-face?

While political activists are noisily trying to silence scientists (see below), the new UN report has quietly done some interesting backtracking, says the WSJ:
Take rising sea levels. In its 2001 report, the U.N.'s best high-end estimate of the rise in sea levels by 2100 was three feet. Lord Monckton notes that the upcoming report's high-end best estimate is 17 inches, or half the previous prediction. Similarly, the new report shows that the 2001 assessment had overestimated the human influence on climate change since the Industrial Revolution by at least one-third.

.... We're told that the upcoming report is also missing any reference to the infamous "hockey stick," a study by Michael Mann that purported to show 900 years of minor fluctuations in temperature, followed by a dramatic spike over the past century. The IPCC featured the graph in 2001, but it has since been widely rebutted.

At present, the UN report is only in draft form, so any of the above can change before publication.
