Leaked IPCC report: Global warming models overestimating warming...

If a climate model is off this much over such a short term, it is useless for long-term forecasting…

Via 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.
