Conservative thinktanks in the US engaging in climate change have increased their attacks on science in recent years, a study of 16,000 documents finds…”While conservative thinktanks were involved in denial from the outset – 1989 at least – we have argued they really moved to the forefront in the late 90s when BP and then other companies pulled out of the industry-led Global Climate Coalition that had arguably been the most powerful force in denial. In fact, the conservative thinktanks were upset that oil companies were ‘caving in’ to the IPCC, and decided to take the lead. This also really shifted the basis of denial from economic self-interest to ideological opposition – the commitment to neoliberalism’s distaste for all government regulations.
