Gerbrand Komen, who was the longtime head of the Dutch government delegation at climate-panel plenary meetings(荷兰政府代表团的负责人参加专家组的全体大会) and is a former director of climate research at the Royal Netherlands Meteorological Institute(荷兰皇家气象学院), said that the climate panel is, in essence, presenting mixed messages and assuming mixed roles.
“I like to distinguish people trying to understand the world and people trying to change the world,” Dr. Komen said in an email. “I.P.C.C. (’policy relevant, but not policy prescriptive’(政策相关但不引导政策制定)) is in between. In all three groups [the climate panel's working groups on the science(科学问题组), impacts and adaptive response(气候变化影响和适应性应对组) and mitigation of human-caused warming(人为原因导致气候变暖应对组)] there are people that ignore uncertainty bands, and emphasize extremes, for various reasons: be it curiosity or the wish to influence policy. Modelers sometimes tend to forget that their models are only models.”
Discussions of climate science and policy have seen endless fights over the appropriate role of scientists. Should they limit themselves to laying out the evidence, uncertainties and all, and let society respond however it may? Or should they be as free as any citizen to dive into the policy debate, as James Hansen of NASA and Dr. Pachauri (who is an engineer and economist) have done?
