who needs peer review? not the ipcc

The BBC has this article (although if you can find it anywhere near the front page you've got better eyes than me) describing scientific method in action.

The UN panel on climate change warning that Himalayan glaciers could melt to a fifth of current levels by 2035 is wildly inaccurate, an academic says. J Graham Cogley, a professor at Ontario Trent University, says he believes the UN authors got the date from an earlier report wrong by more than 300 years. He is astonished they "misread 2350 as 2035".

The article goes on to allege that many of the papers the IPCC use for their predictions are not peer-reviewed.

When asked how this "error" could have happened, RK Pachauri, the Indian scientist who heads the IPCC, said: "I don't have anything to add on glaciers."

The IPCC relied on three documents to arrive at 2035 as the "outer year" for shrinkage of glaciers. They are: a 2005 World Wide Fund for Nature report on glaciers; a 1996 Unesco document on hydrology; and a 1999 news report in New Scientist.

Incidentally, none of these documents have been reviewed by peer professionals, which is what the IPCC is mandated to be doing.

Which is then confirmed to be correct

Murari Lal, a climate expert who was one of the leading authors of the 2007 IPCC report, denied it had its facts wrong about melting Himalayan glaciers. But he admitted the report relied on non-peer reviewed - or 'unpublished' - documents when assessing the status of the glaciers.

The science is settled? Pull the other one.
