Less than a week after UN Secretary General Ban Ki-moon urged developing nations to commit billions of dollars to fight the effects of climate change, the U.N.’s Intergovernmental Panel on Climate Change (IPCC) released a well-timed preliminary report that basically said its climate models were fairly useless at the moment. In the process, they also threw out basic scientific principles by stating that extreme weather events would become more common, and that its climate models didn't have practical predictability.
If it sounds like the IPCC wants its cake without it melting first, you'd be correct. Keep in mind that the next official release from the IPCC (and its myriad working groups) isn't until 2014, but that hasn't stopped the bureaucrats who run the IPCC from issuing a report that backs up the claims made by the UN Secretary General.
So how did the IPCC come to these conclusions? The following admission by Chris Fields, a co-author of this recent report, comes from a Reuters news article:
Sceptics have questioned the models the IPCC uses to make its climate predictions, but Fields defended the science: “There are many cases in which just from observations, we’ve seen a change,” he said.
“Climate models are only some of the tools used to make future projections. Some … are based on projecting historical data forward or what we know about the physics of the system. Lots of observations are built in for us to test how they work.”
