We are in the grip of climate-change catastrophism

Movement's catchphrase is that the science is settled, but science is never settled and good policy takes that into account
For example, the end of the Little Ice Age is invariably the starting point for calculating a global temperature increase — which is like a government calculating its effects on economic growth by starting at the trough of the last recession. Confirmation bias is provided by influencers, including uniquely unqualified Hollywood stars, who propagate the doctrine of the faith. Fear is employed as a powerful motivator and is inculcated from childhood. Apocalyptic doom is preordained for collective disobedience and salvation promised for devotees and repentants who comply with onerous strictures, many of which have no practical utility.
