“The public discourse on global warming has little in common with the standards of scientific discourse. Rather, it is part of political discourse where comments are made to secure the political base and frighten the opposition rather than to illuminate issues. In political discourse, information is to be 'spun' to reinforce pre-existing beliefs, and to discourage opposition.”
