Abstract
This paper addresses the representation of scientific uncertainty about global warming and climate change in the U.S. popular press. An examination of popular press articles about global warming from 1986 to 1995 reveals that scientific uncertainty was a salient theme. The paper describes several forms of uncertainty construction and means through which it was managed. I argue that scientific uncertainty was used to help construct an exclusionary boundary between “the public” and climate change scientists. This rhetorical boundary delegitimated lay knowledge by suggesting that the public did not hold appropriate reverence for scientific uncertainty and the need for more research.
