I've been at the Climatic Research Unit and Hadley Centre and can actually confirm that there is a lot of debate going on about AGW, and although there is indeed a consensus that humans are probably at least partly to blame, the science, indeed, is not as settled as various media sources would have us believe (one way or the other!) The question of perception is an interesting one, as highlighted recently on wunderground. Polls in the US showed that 42% of Americans believe that - "there is a lot of disagreement among climate scientists about whether human activities are a major cause" of global warming". When the question was asked of the weather underground community, a group like here which one might expect to be more aware of the issues and have a fair share of 'meteo geeks', the percentage was higher at 56%. However, 82% of all scientists questioned, and fully 97% of the climate scientists who regularly publish on climate change agreed with the statement, "human activity is a significant contributing factor in changing mean global temperatures". http://www.wunderground.com/blog/JeffMaste...l?entrynum=1184 Thus it appears La Bise has a fair point and the most vociferous and possibly entrenched and ill-informed arguments are taking place on forums such as this.
