WestVirginiaRebel Posted January 29, 2013 Share Posted January 29, 2013 Fox News: A preliminary draft of a report by the U.N.’s Intergovernmental Panel on Climate Change was leaked to the public this month, and climate skeptics say it contains fresh evidence of 20 years of overstated global warming. The report -- which is not scheduled for publication until 2014 -- was leaked by someone involved in the IPCC’s review process, and is available for download online. Bloggers combing through the report discovered a chart comparing the four temperature models the group has published since 1990. Each has overstated the rise in temperature that Earth actually experienced. “Temperatures have not risen nearly as much as almost all of the climate models predicted,” Roy Spencer, a climatologist at the University of Alabama at Huntsville, told FoxNews.com. “Their predictions have largely failed, four times in a row... what that means is that it's time for them to re-evaluate,” Spencer said. The IPCC graph shows that the midpoints of the various models predicted that the world would warm by between about 0.5 degrees Fahrenheit and 0.9 degrees Fahrenheit between 1990 and 2012. Actual warming was much less than that: 0.28 F, according the data the IPCC cites. But that doesn’t mean the IPCC models are wrong, others argue. “It’s important to keep in mind that there are natural short-term variations in global temperature that happen right alongside human-induced warming,” Aaron Huertas, of the Union of Concerned Scientists, told FoxNews.com. “For instance, it would have been impossible for the IPCC to predict if a volcanic eruption might temporarily cool the Earth, as the Mount Pinatubo eruption did in 1991.” The IPCC’s climate report draft also notes that “the model projections ... do not fully account for natural variability.” ________ Propaganda is still propaganda...
