Naomi Oreskes, Professor of History and Science Studies at the University of California San Diego is about to release her book Merchants of Doubt.
She published a literature survey of peer-reviewed scientific papers on global climate change in the Science Journal, Dec 2004. From that she tells that she got a huge amount of hate mail and threats. Instead of being intimidated she, as a historian, instead took this as raw material and began investigating what's behind this wingnuttery. I do think the deniers now regret this.
Naomi Oreskes discusses her new book "Merchants Of Doubt" 4:00 minute youtube
If you haven't caught her before - or you would like a review of the history of science regarding climate change potential via CO2 - she does this in the first 1/2 of this video at the University of California TV (58 minutes, Dec2007) - the 2nd half being the manufacture of "scientific debate".
(Tim Lambert has a chapter list here and discussion of the video)
She now has a later video (1hour13min, Mar2010) discussing her book, also doing a quick review of the history. Watch the latter if you're time constrained but both are very good.
I'm looking forward to getting a copy of her book.
