A review of the Intergovernmental Panel on Climate Change's (IPCC) report on the impact of global warming has concluded that, despite errors, the main conclusions of the report are valid.

Released in 2007, the report details the negative impact that climate change will have on the world. It has come under criticism for a number of inaccuracies.

The Dutch government called for the review of the report, which was conducted by the Netherlands Environmental Assessment Agency (PBL).

While a number of minor mistakes were identified, the PBL concluded that there were "no errors that would undermine the main conclusions".

However, the PBL said that the IPCC had focused on the "worst-case scenarios" in many instances.

One of the most significant mistakes made was the prediction that the glaciers in the Himalayas would disappear by the year 2035, which the IPCC admits is unlikely.

The suggestion in the report's summary that 75 million to 250 million Africans could be facing a lack of water by 2020 was also inaccurate, according to the PBL, which estimates the figure instead to be in the region of 90 million to 220 million.

Recently, the IPCC selected the authors who will contribute to its fifth assessment report, which will be released in 2013 or 2014.
