The Hubert Lamb Building, University of East Anglia, where the Climatic Research Unit is based

The Climatic Research Unit (CRU) is a component of the University of East Anglia and is one of the leading institutions concerned with the study of natural and anthropogenic climate change.[1]

With a staff of some thirty research scientists and students, the CRU has contributed to the development of a number of the data sets widely used in

global temperature records used to monitor the state of the climate system,[2][3] as well as statistical software packages and climate models.[4]

History

The CRU was founded in 1972 as part of the university's School of

Royal Dutch Shell.[6] The Rockefeller Foundation was another early benefactor, and the Wolfson Foundation gave the Unit its current building in 1986.[5] Since the second half of the 1970s the Unit has also received funding through a series of contracts with the United States Department of Energy to support the work of those involved in climate reconstruction and analysis of the effects on climate of greenhouse gas emissions.[7] The UK Government (Margaret Thatcher) became a strong supporter of climate research in the mid-1980s.[8]

The first director of the unit was Professor

climatological community had for years argued that the climate system was in fact highly variable on timescales of decades to centuries and longer. The establishment of the CRU enabled Lamb and his colleagues to focus on this issue and eventually to win the argument decisively.[5]

Hubert Lamb retired in 1978. His successors were

Tim Osborn (from January 2017);[8][10] Peter Liss was acting director during investigations between December 2009[11] and July 2010.[12] In 1984, the unit moved to a new cylindrical building designed by Rick Mather.[13] In 2006, this was named the Hubert Lamb Building in honour of the first director.[14]

Activities

At the time of its establishment the CRU set out four key aims, which still remain valid:

CRU produces a range of climate datasets, covering temperature,

temperature record.[17] First compiled in the early 1980s, the record documents global temperature fluctuations since the 1850s. The CRU compiles the land component of the record and the Hadley Centre provides the marine component. The merged record is used by the Intergovernmental Panel on Climate Change in all its publications.[7]

Other products include the CRU TS high resolution gridded land surface dataset of multiple factors including precipitation, vapour pressure and cloud cover as well as temperatures.[18] This type of dataset can be used to monitor drought conditions, for example.

CRU is also involved in a study of Eurasian climate over the last 10,000 years based upon

National Meteorological Organisations that originated the data; CRU retains most but not all of the raw data, which continues to be held by the originating services.[20]

It published a quarterly journal, Climate Monitor.[19] This ceased publication in 1998, being replaced by an online version, Climate Monitor Online.[21]

Release of raw meteorological data

Main article: Freedom of Information requests to the Climatic Research Unit

The CRU collates data from many sources around the world. In August 2009 its director, Phil Jones, told the science journal

Stephen McIntyre and people affiliated with his Climate Audit blog requesting access to raw climate data or information about their use.[22]

In early 2011 a large amount of raw weather station data had been released by the Met Office and the US Global Historical Climatology Network, but around two-thirds of the data owners did not respond to the CRU requests for agreement, and both Poland and Trinidad and Tobago declined. Two FOIA requests for data shared with another researcher were refused by the university, and the requestors appealed this to the Information Commissioner's Office (ICO). In its decision released on 23 June 2011, the ICO required CRU to release the remaining raw data irrespective of the wishes of the meteorological organisations which owned the data. This decision included data from Trinidad and Tobago but did not cover Poland. The raw data release was completed by 27 July 2011.[23]

CRU email controversy

Main article: Climatic Research Unit email controversy

In November 2009,

global warming conspiracy theory that scientists had allegedly conspired to manipulate data[26][27][28] and to keep scientists who have contrary views out of peer-review literature.[29][30] This controversy was dubbed "Climategate".[31][32]

A series of independent public investigations of the allegations found no evidence of fraud or scientific misconduct.[33] The Muir Russell report exonerated the scientists, but found "a consistent pattern of failing to display the proper degree of openness, both on the part of CRU scientists and on the part of the UEA".[34][35] The scientific consensus that global warming is occurring as a result of human activity remained unchanged.[36]

In 2011, a new analysis of temperature data by the independent

Berkeley Earth Surface Temperature group, many of whom had stated publicly that they thought it was possible that the CRU had manipulated data, concluded that "these studies were done carefully and that potential biases identified by climate change sceptics did not seriously affect their conclusions".[37]
