Yet another credibility issue has arrived for the Inter-governmental Panel on Climate Change (IPCC), as now the UN climate change body has been blamed to pass a faulty report on disappearing Amazon forests.

The claims say that the reports based on a report by environmental activists while that on disappearing ice from the world's mountain peaks is based on a doctoral student's essay and an article in a mountaineering magazine.

The report by IPCC describes global warming as a major reason for reductions in mountain ice in the Andes, Alps and Africa. The report considered two scientific papers as its primary source of information. But on the other hand, the UK's Sunday Telegraph claimed that the two sources were actually an article published in a magazine for mountaineers and a geography student's master's dissertation. It says further that unreliable evidence about the changes, which were witnessed during climbs by the authors, were considered for writing the article, published in the mountaineering magazine - Climbing News. On the other hand, reports are that the dissertation by a student from the University of Bern in Switzerland quoted interviews with mountain guides in the Alps.

The IPCC has noted a report by the environment group WWF in order to strengthen its claims that the large tracts of Amazonian forests will disappear because of diminishing rainfall. However, the IPCC's decision to quote a WWF report to support its claim that 40% of Amazon forests could vanish due to diminishing rainfall and even be replaced by tropical savannah, has been questioned by the Sunday Telegraph.

As per UK's secretary of state for energy and climate change Ed Miliband, it will be completely irresponsible to permit recent controversies over scientific data to undermine the fight against climate change.

IPCC as of now is being pressurized to improve its procedures.
