The checks and balances on the political behavior of scientists need to be provided by scientists through their professional organizations and their education of the next generation of scientists. After all, scientists have the most to lose if the integrity of their profession is reduce to the level of politicians and lawyers. If that happened, would the public continue their generous funding of science?
Climate science is a relatively new science without a long history of tradition or mistakes that have be exposed. With the massive increase in funding around 1990, climate science is populated by many activists who were “looking to make the world a better place” in their formative years. Under these circumstances, climate science is unlike to impose effective checks and balances on themselves.
For non-activists, Steven Schneider’s infamous quote about “telling scary stories” and “telling the truth, the whole truth, and nothing but the truth – which means that we must include all the doubts, the caveats, the ifs, ands, and buts” perfectly describes the difference between science and policy advocacy. Policymakers, citizens, and the press deserve to know whether a scientist talking to them is speaking as a scientist or a policy advocate. Scientific societies should emphasize the difference between these two roles and recommended that scientists always explain whether they are speaking as scientists or policy advocates. Every citizen has the right to advocate for public policy and scientists are highly qualified advocates. Unfortunately, they demean my profession when they audience thinks their “scary stories” are “the truth” with all of the caveats. The Climategate emails show that highly vocal policy advocates have have difficulty keeping policy considerations out of their science.
When the IPCC insists on reporting a “scientific consensus’, rather than the range of scientific opinion and “all of the doubts…”, they are admitting that they are functioning as policy advocates, not scientists.
