Neutral advice from the IPCC?
By Richard Ingham (AFP) – 3 hours ago
PARIS — A leaden cloak of responsibility lies on the shoulders of UN scientists as they put the final touches to the first volume of a massive report that will give the world the most detailed picture yet of climate change.
Due to be unveiled in Stockholm on September 27, the document will be scrutinised word by word by green groups, fossil-fuel lobbies and governments to see if it will yank climate change out of prolonged political limbo.
The report will kick off the fifth assessment by the Intergovernmental Panel on Climate Change (IPCC), an expert body set up in 1988 to provide neutral advice on global warming and its impacts. http://www.google.com/hostednews/afp/article/ALeqM5hHmcL4DZjT-PZWhEHO3VDb5gjsrA?docId=CNG.db54bf0fa84dd93ad7cf71578fe1dcef.681
Regarding your “Trenberth’s IPCC claim” post, you may like to mention Green & Armstrong (2007) (available here) in which we addressed Trenberth’s IPCC-don’t-forecast line in some detail. As far as I’m aware, our subsequent paper (Green, Armstrong, & Soon 2009, here) provides the *only* forecast of global mean temperatures over the 21st Century. That is, we state that we are making a forecast (not a scenario or projection), the forecast is stated clearly (annual average temperatures will be within 0.5 C of the 2008 figure), and is unconditional (no matter what happens to CO2 emissions, etc). Unlike Trenberth et al., who try to have it both ways by calling for “action” but aren’t prepared to say they are making forecasts, we stand by our forecast and the clear implication that government climate policies are neither needed nor desirable.

Park Service personnel recently discovered evidence of a buried forest dating back to at least 1170 AD high in the Forelands near the current glacier’s edge…Exit Glacier advanced from the Harding Icefield during the Little Ice Age, burying this existing forest and advancing to a maximum marked by the terminal moraine dated to 1815…
Eastern US water supplies threatened by a legacy of acid rain
Noted ecologist Gene Likens, founding director of the Cary Institute of Ecosystem Studies and a co-discoverer of acid rain, was among the study’s authors. The extent of alkalinity change in streams and rivers exceeded his expectations: “This is another example of the widespread impact humans are having on natural systems. Policymakers and the public think that the acid rain problem has gone away, but it has not.”
Dr. Roy Spencer continues his greenhouse experiments:
In Part I of this series, I mentioned how Wood’s (1909) “greenhouse box” experiment, which he claimed suggested that a real greenhouse did not operate through “trapping” of infrared radiation, was probably not described well enough to conclude anything of substance. I provided Wood’s original published “Note”, which was only a few paragraphs, and in which he admitted that he covered the issue in only cursory detail.
Wood’s experiment was not described well enough to replicate. We have no idea how much sunlight was passed through his plate of rock salt-covered box versus the glass-covered box. We also don’t know exactly how he placed another glass window over the rock salt window, which if it was very close at all, invalidated the whole experiment.
New witch hunt: “Environmental Campaign Suggests Naming Vicious Storms After Climate-Change Deniers”
New York agency Barton F. Graf has turned its roguish attention to the issue of climate change, and is helping 350 Action, a climate change activist group, with the amusing video below. According to the YouTube description: “Since 1954, the World Meteorological Organization has been naming extreme storms after people. But we propose a new naming system. One that names extreme storms caused by climate change, after the policy makers who deny climate change and obstruct climate policy. If you agree, sign the petition at climatenamechange.org.” The snarky tone preaches to the choir, but it’s hard to resist lines like, “If you value your life, please seek shelter from Michele Bachmann.”
Satellite temps flat for 200 months now

If the global warming era started in June 1988 with Jim Hansen’s drama-queen congressional testimony, then atmospheric temps have been flat 67% of the time since.
