Conspiracy theories that promote climate-change skepticism and denial spread rapidly across the internet ahead of the United Nation's ongoing COP26 Climate Change summit in Glasgow, Scotland.

The technology firm's platform uses machine-learning algorithms to scan millions of posts across mainstream social networks — including Twitter, Telegram, fringe sites and others — and, aided by human analysts, identified four major climate denial trends targeting U.S. and European climate-change policy.
