The UN's climate science body needs "fundamental" reforms, including a shorter term for its chairperson, an international review has concluded.
The Intergovernmental Panel on Climate Change (IPCC) has faced mounting pressure over errors in its last major assessment of climate science in 2007.
The review commends the IPCC on the way it carried out previous assessments.
But the report recommends changes to the way the body is run and the way science is presented.
Critics have previously called on the UN panel's chair, Dr Rajendra Pachauri, to resign. Responding to the report at a news conference in New York, Dr Pachauri said he wanted to stay to implement changes at the organisation.
The IPCC has admitted it made a mistake in its 2007 climate assessment in asserting that Himalayan glaciers could disappear by 2035. But officials at the UN organisation said this error did not change the broad picture of man-made climate change. BBC News
