When leading climate scientists are asked anonymously or off-the-record what they actually expect we will have to endure in the decades ahead, you'll find they are not very optimistic.
In 2021, the journal Nature conducted an anonymous survey of IPCC authors and received responses from 92 scientists. Their answers suggest strong skepticism that governments will significantly slow the pace of global heating, despite all those fancy promises we've heard ("blah-blah-blah").
Six in ten of the survey respondents expect the world to warm by at least 3°C by the end of the century. Some think 4°C or even 5°C is where we're headed. Fewer than 5% of these scientists believe we will stay under 1.5°C, which is the optimistic — and totally unrealistic — outcome that politicians and the major media want you to swallow.
