The main findings of the Independent Climate Change E-mails Review (―the Review‖) are set out in Section 1.3 below, and the main recommendations in Section 1.4. We comment in Section 1.5 on some of the more general issues raised by the Review that we think are important about the context in which scientists operate and in which science contributes to public policy. 1.1 Introduction 2. In November 2009, approximately 1000 e-mails from the Climatic Research Unit (CRU) of the University of East Anglia (UEA) were made public without authorisation. 3. CRU is a small research unit which over the last 30 years has played an important role in the development of climate science, in particular in their work on developing global temperature trends. 4. The e-mails fuelled challenges to the work of CRU, to the reliability of climate science generally, and to the conclusions of the Intergovernmental Panel on Climate Change (IPCC). All this happened shortly before the Copenhagen Summit, and was extensively referred to there. 5. In response, the UEA commissioned two inquiries. The first led by Lord Oxburgh, into the science being undertaken at CRU, has already reported. This document is the report of the second inquiry – The Independent Climate Change E-mails Review – which examines the conduct of the scientists involved and makes recommendations to the University of East Anglia. Our inquiry addresses a number of important allegations that were made following the e-mail release. 6. The allegations relate to aspects of the behaviour of the CRU scientists, such as their handling and release of data, their approach to peer review, and their role in the public presentation of results. 7. The allegations also include the assertion that actions were taken to promote a particular view of climate change by improperly influencing the process of advising policy makers. Therefore we have sought to understand the significance of the roles played by those involved from CRU and of the influence they had on the relevant outcomes. 8. The Review examines the honesty, rigour and openness with which the CRU scientists have acted. It is important to note that we offer no opinion on the validity of their scientific work. Such an outcome could only come through the normal processes of scientific debate and not from the examination of e-mails or from a series of interviews about conduct. 10 CHAPTER 1: EXECUTIVE SUMMARY 1.2 The Review Process 9. The approach taken by the Review was to identify and investigate the allegations to which the e-mails gave rise. This reflected our reading of the emails and the comments made on them. An online consultation was undertaken to ensure that the Team‘s initial analysis of the allegations and concerns was sound.
