From 1989 to 2002, several large US companies, including the oil companies Exxon and the US subsidiaries of Shell and BP, sponsored a lobbying organisation called the Global ClimateCoalition (GCC), to counter the strengthening consensus that human carbon dioxide emissions posed a serious threat to the Earth’s climate. As has been documented by Hoggan and Littlemore and Oreskes and Conway, the GCC and its fellow travellers took a leaf out of the tobacco industry’s playbook and attempted to counter the message of peer-reviewed science by deliberately sowing doubt through emphasizing uncertainties and unknowns. The climatescientist Benjamin Santer accused the GCC of deliberately suppressing scientific information that supported the IPCC consensus.
