The IPCC came under fire after using the wrong date for Himalayan glacier melt
The UN's climate science body needs fundamental reforms to the way it is managed, 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
The review was overseen by the Inter-Academy Council, which brings together bodies such as the UK's Royal Society.
The IAC recommends that the IPCC appoint an executive director to handle day-to-day operations and speak on behalf of the body.It also said the current limit of two six-year terms for the chair of the organisation is too long.
The report says that the post of IPCC chair, currently occupied by Dr Rajendra Pachauri, and that of the executive director should be limited to the term of one climate science assessment.
