Institute of Physics damns the Climategaters' "science"

I certainly think that those people who think that this genie can just be put back into its bottle are mistaken. Too much has now come out for a return to the previous orthodox status quo.

The Institute of Physics, representing 36,000 members, submits a devastating assessment of Climategate to the British parliamentary inquiry into the scandal:
2. The CRU e-mails as published on the internet provide prima facie evidence of determined and co-ordinated refusals to comply with honourable scientific traditions and freedom of information law. The principle that scientists should be willing to expose their ideas and results to independent testing and replication by others, which requires the open exchange of data, procedures and materials, is vital…

3. It is important to recognise that there are two completely different categories of data set that are involved in the CRU e-mail exchanges:

· those compiled from direct instrumental measurements of land and ocean surface temperatures such as the CRU, GISS and NOAA data sets; and

· historic temperature reconstructions from measurements of ‘proxies’, for example, tree-rings.

4. The second category relating to proxy reconstructions are the basis for the conclusion that 20th century warming is unprecedented. Published reconstructions may represent only a part of the raw data available and may be sensitive to the choices made and the statistical techniques used. Different choices, omissions or statistical processes may lead to different conclusions. This possibility was evidently the reason behind some of the (rejected) requests for further information.

5. The e-mails reveal doubts as to the reliability of some of the reconstructions and raise questions as to the way in which they have been represented; for example, the apparent suppression, in graphics widely used by the IPCC, of proxy results for recent decades that do not agree with contemporary instrumental temperature measurements.

6. There is also reason for concern at the intolerance to challenge displayed in the e-mails. This impedes the process of scientific ‘self correction’, which is vital to the integrity of the scientific process as a whole, and not just to the research itself. In that context, those CRU e-mails relating to the peer-review process suggest a need for a review of its adequacy and objectivity as practised in this field and its potential vulnerability to bias or manipulation.

7. Fundamentally, we consider it should be inappropriate for the verification of the integrity of the scientific process to depend on appeals to Freedom of Information legislation. Nevertheless, the right to such appeals has been shown to be necessary. The e-mails illustrate the possibility of networks of like-minded researchers effectively excluding newcomers...
This submission in effect warns that this recent warming may not be unprecedented, after all, and those that claim it is may have been blinded by bias or simply fiddled their results and suppressed dissent.

I’ll repeat: Climategate reveals the greatest scientific scandal of our lifetime.

Hmm.. I've thought about this very much..... it sure raises a few questions..

To be a upright benign being is to have a kind of openness to the far-out, an skill to trusteeship undeterminable things beyond your own restrain, that can govern you to be shattered in uncommonly exceptionally circumstances on which you were not to blame. That says something very weighty about the prerequisite of the principled autobiography: that it is based on a trust in the fitful and on a willingness to be exposed; it's based on being more like a spy than like a jewel, something somewhat tenuous, but whose extremely item attractiveness is inseparable from that fragility.
