Here is one from the blog "junkscience." Malloy doesn't think much of this report. Note the comment from the IPCC at the end where it is admitted that climate models are tricky, and are not well understood. It astonishes me that politicians are willing to enact draconian laws that will adversely affect the lives of poor people based on models that have such poor reliability.

We're sure everyone knows this has been published: Scientific Assessment of the Effects of Global Change on the United States - A Report of the Committee on Environment and Natural Resources National Science and Technology Council

I've been back on deck since Saturday and trying to read through this since. Unfortunately it is a seriously painful collection of weasel words and outright horseshit. Why anyone would bother to publish it is a mystery to me because it contains exactly zero useful information and a great deal of blatant misinformation. The modeling exercises are complete rubbish and it even throws in the old ozone chestnut (in case you don't know stratospheric ozone is largely irrelevant due to Earth's 20% oxygen atmosphere limiting UV penetration to ground level and the tropics receive as much irradiation on any given day as allegedly 'depleted' regions receive throughout the year -- guess where life thrives?).

I get the impression it is the result of a committee effort with members from Greenpeace, Sierra, NRDC, UCS and other misanthropic Gaia nuts. Excellent example of exactly what is wrong with what currently passes for 'climate science'.

Key point: even the IPCC admits "The climate system is particularly challenging since it is known that components in the system are inherently chaotic; there are feedbacks that could potentially switch sign, and there are central processes that affect the system in a complicated, non-linear manner. These complex, chaotic, non-linear dynamics are an inherent aspect of the climate system. ... We simply do not fully understand the causes of climate drift in coupled models."
