Despite 97 per cent of scientists agreeing on anthropogenic global warming, the remaining 3 per cent play a critical role in keeping the debate about climate consensus alive. Analysis of climate change contrarians from multi-signatory documents reveals 3 per cent of signees to be climate experts, while the remaining 97 per cent do not meet expert criteria and are also involved with organizations and industries who make up the climate change countermovement. The data also reveal most contrarians to be aged sixty-five or older. As a result, we explore other factors (for example, collective memories and ideological views) that may have also contributed to expert and non-expert views.
