This is looking more and more like a farce:
This is to be found in Chapter 13 of the Working Group II report, the same part of the IPCC fourth assessment report in which the “Glaciergate” claims are made. There, is the startling claim that:
“Up to 40% of the Amazonian forests could react drastically to even a slight reduction in precipitation; this means that the tropical vegetation, hydrology and climate system in South America could change very rapidly to another steady state, not necessarily producing gradual changes between the current and the future situation (Rowell and Moore, 2000). It is more probable that forests will be replaced by ecosystems that have more resistance to multiple stresses caused by temperature increase, droughts and fires, such as tropical savannas.”
At first sight, the reference looks kosher enough but, following it through, one sees:
Rowell, A. and P.F. Moore, 2000: Global Review of Forest Fires. WWF/IUCN,
Gland, Switzerland, 66 pp. http://www.iucn.org/themes/fcp/publications
This, then appears to be another WWF report, carried out in conjunction with the IUCN – The International Union for Conservation of Nature. The link given is no longer active, but the report is on the IUCN website here. Furthermore, the IUCN along with WWF is another advocacy group and the report is not peer-reviewed. According to IPCC rules, it should not have been used as a primary source.
