Phil Willis MP, Committee Chair, said:
"Climate science is a matter of global importance. On the basis of the science, governments across the world will be spending trillions of pounds on climate change mitigation. The quality of the science therefore has to be irreproachable.
"What this inquiry revealed was that climate scientists need to take steps to make available all the data that support their work and full methodological workings, including their computer codes. Had both been available, many of the problems at CRU could have been avoided."
Climatic Research Unit
The focus on Professor Jones and CRU has been largely misplaced. On the accusations relating to Professor Jones’s refusal to share raw data and computer codes, the Committee considers that his actions were in line with common practice in the climate science community but that those practices need to change.
On the much cited phrases in the leaked emails - "trick" and "hiding the decline" - the Committee considers that they were colloquial terms used in private emails and the balance of evidence is that they were not part of a systematic attempt to mislead.
Insofar as the Committee was able to consider accusations of dishonesty against CRU, the Committee considers that there is no case to answer.
The Committee found no reason in this inquiry to challenge the scientific consensus as expressed by Professor Beddington, the Government Chief Scientific Adviser, that "global warming is happening [and] that it is induced by human activity".
But this was not an inquiry into the science produced by CRU and it will be for the Scientific Appraisal Panel, announced by the University on 22 March, to determine whether the work of CRU has been soundly built.
Freedom of Information requests
On the mishandling of Freedom of Information (FoI) requests, the Committee considers that much of the responsibility should lie with the University, not CRU. The leaked emails appear to show a culture of non-disclosure at CRU and instances where information may have been deleted to avoid disclosure, particularly to climate change sceptics.
The failure of the University to grasp fully the potential damage this could do and did was regrettable. The University needs to re-assess how it can support academics whose expertise in FoI requests is limited.
