Doomism

There are people and organisations that reject the scientific consensus on climate change and global heating. These are often referred to as climate denialists, contrarians, dismissives, or sceptics/skeptics (incorrectly, since true scepticism is critical thinking, not dogmatic belief).

There are also some who accept the reality of climate change but reject the science on its likely consequences. One group is those who claim effects will be far less severe than the scientific consensus predicts; these are sometimes known as "luke-warmists" or "climate complacents".

There is another faction who claim that effects will be far worse than consensus predictions, with consequences ranging up to extinction of humanity itself within a short period. These talk of "Deep Adaptation" or "Near-Term Human Extinction" and are sometimes referred to as "doomists" or "catastrophists".

In a guest article on RealClimate, "Denial and Alarmism in the Near-Term Extinction and Collapse Debate", Alastair McIntosh, honorary professor in the College of Social Sciences at the University of Glasgow in Scotland, discusses climate change dismissives, and doomists.
