[Hans von Storch posted this very thoughtful comment on the thread from last week on the recent partnership of leading climate scientists and the National Association of Evangelicals to advocate for political action on climate change. We think that Hans' comments deserve a bit more prominence so have reproduced them here. -RP]
I remember that there was a few years ago a web page in UK, which made public a statement of a religious group about climate change; a very concerned statement. It was signed by, among others Sir John Houghton (who signed in his capacity of former IPCC chair), Bob Watson and other brass of the IPCC guild [The UK statement referred to can be found here. -RP]. Thus, the disclosure of the encroachment of religion into top climate science levels is nothing new. It would have been better if this group had been open about this fact earlier.
We all are bound by certain culturally constructed values; religion is just one, and it has been particularly barbarian in times. In other times rather humanitarian. For a scientist the problem is that these values interfere with our analytical skills; not in the sense that we would execute statistical tests in a biased manner or that we would fail in our maths. But in the way we ask; in our preparedness to accept certain answers or to remain skeptical to certain answers. And finally, it may lead us to misuse our scientific authority to push for conclusions, which are beyond the realm of science.
None of us is free of this interference: this group is to be applauded for being explicit and honest. But they should also accept that claims of independence have to be given up when speaking about the social implications of anthropogenic climate change. They are, and likely have been, issue advocates. They are certainly still scientists, but they are advocates as well. In a sense they are publicly paid NGOs. NGOs play an important and welcomed role in the public discussion and decision process, like most other lobbying groups – but everybody knows what their agenda is.
Those of us who want to try to limit the influence of our values on our scientific analyses, should try to analyze these values and their potential influence on our professional performance. We should see our present activity in a historical context and reflect upon our cultural and social conditioning. We may be able to limit the degree of subjectivity of our work to some, maybe just a very minor, extent.
