Fiabilidade científica nas alterações climáticas

UN climate change panel based claims on student dissertation and magazine article: The United Nations' expert panel on climate change based claims about ice disappearing from the world's mountain tops on a student's dissertation and an article in a mountaineering magazine. [...]

In its most recent report, [Intergovernmental Panel on Climate Change] stated that observed reductions in mountain ice in the Andes, Alps and Africa was being caused by global warming, citing two papers as the source of the information.

However, it can be revealed that one of the sources quoted was a feature article published in a popular magazine for climbers which was based on anecdotal evidence from mountaineers about the changes they were witnessing on the mountainsides around them.

The other was a dissertation written by a geography student, studying for the equivalent of a master's degree, at the University of Berne in Switzerland that quoted interviews with mountain guides in the Alps.

The revelations, uncovered by The Sunday Telegraph, have raised fresh questions about the quality of the information contained in the report, which was published in 2007. [...]

The IPCC failed to respond to questions about the inclusion of unreliable sources in its report but it has insisted over the past week that despite minor errors, the findings of the report are still robust and consistent with the underlying science.
