Global warming, like many other environmental controversies, mixes pervasive uncertainty with the certainties of expert (but contradictory) opinion. How can we know who is right about global warming, if the only things we have to work with are the scientists’ competing scenarios, the truth‐value of which has yet to be established? One approach is to rely on narrative policy analysis to identify the non‐scientific, but policy‐relevant role played by the global warming controversy. This approach shows that the controversy signals a (...) wider “analytic tip” taking place in the examination of major public policy problems, a tip toward the notion that issues which can still be effectively dealt with locally, regionally or nationally must now first be addressed globally. The policy implications of analytic tip and the narrative features of the global warming scenario are profound for both environmentalists and their ideological opponents. (shrink)
