IPCC Fifth Assessment Report (AR5)

27 September 2013

The main findings of Working Group 1 of the Intergovernmental Panel on Climate Change (IPCC) have been published today.

The first part of the Fifth Assessment Report, entitled 'Climate Change 2013: The Physical Science Basis', will be available in full on 30 September 2013. It presents a synthesis of current climate science research and an assessment of the extent to which the climate changes can be attributed to human activity. It builds on a series of earlier reports on this subject, the most recent of which was published in 2007. These reports are critical in informing the climate policies adopted by governments.

Based on the review and analysis of several thousand published scientific papers, the report has been written and edited by scientists, experts in their field, drawn from 39 countries. More than 10% of these authors are from the UK and many of them are NERC-funded.

NERC funds research on the whole Earth system that contributes to the evidence base from which IPCC draws its conclusions. The peer-reviewed papers of NERC-funded researchers in higher education institutions and in NERC's research centres have made a major contribution to the report in areas such as climate history, loss of ice from ice sheets and glaciers, ocean circulation and ocean warming, climate modelling, sea-ice cover and sea-level rise.
