Now it is often argued that the policy-makers pressure the scientists. Without entering into that debate, what would you [MGW] do to reduce that pressure, while still permitting the original goals of the IPCC to be met?
Vaughn, I did not respond to that comment because its premise is debatable and because I am not comfortable with the topic. My interests are parochial and I have usually avoided IPCC matters.
I do not mean debatable in that I contest the premise, but instead ask myself why initiate a string of comments where inevitably someone will contest that premise—in earnest or for sport? I am tired of that and so I will comment more generally.
Pressures are a fact of life and would exist regardless of how things are shuffled. It is important to note that pressures in various forms also may go the other way—-from the scientists directed at the policy makers. There has been plenty of discussion on aspects of that, e.g., advocacy. It might be of value to address the pressures from both sides at the same time. I also would be a good idea to revisit the role of the IPCC. More people are aware of issues than 20 or 30 years ago [assumption]. Besides any long term program should be periodically thoroughly re-assessed.
From my point-of view handling pressures begins to get at the extent of and how one might perceive science being re-scientized and policy being re-politicized. Further I think that the norm suggested by von Storch is a starting point. The details there are reasonable to me but paramount is the idea of agreement on a norm of interaction including agreement on handling disputes before the public. All of this would be in light of what has been learned—if anything—over the past couple of decades.
But all of this is opinion intended for the sake of discussion and it will not buy a can of beans. Also the reality is that in the bigger decision-making realm time is a factor.
