UN Secretary-General Ban Ki-moon has said that a group of national science academies will review UN climate science to restore trust after a 2007 global warming report was found to have errors.
The UN Intergovernmental Panel on Climate Change acknowledged in January its report had exaggerated the pace of Himalayan glaciers melting.
The IPCC last month said the report had also overstated how much of the Netherlands is below sea level.
'Let me be clear - the threat posed by climate change is real,' Mr Ban said alongside panel chairman Rajendra Pachauri.
'Nothing that has been alleged or revealed in the media recently alters the fundamental scientific consensus on climate change.'
Mr Ban acknowledged that were 'a very small number of errors' in what is known as the Fourth Assessment Report published in 2007, a document of more than 3,000 pages that cited over 10,000 scientific papers.
The next such report on climate change will be published in 2013 and 2014.
Despite the errors, Mr Pachauri said he stood by the 2007 report's principle message that global warming is real and is accelerating due to greenhouse gas emissions.
'We believe the conclusions of that report are really beyond any reasonable doubt,' said Mr Pachauri, who has been resisting calls from critics for his resignation.
Mr Ban said the InterAcademy Council, a grouping of the world's science academies, would lead the review, which he promised would be 'conducted completely independently of the United Nations'.
The IPCC shared the 2007 Nobel Peace Prize with former US Vice President Al Gore.
Its 2007 report wrongly said Himalayan glaciers could vanish by 2035, a prediction derived from articles that had not been reviewed by scientists before publication.
