Bread and CircusesMost climate scientists, when asked privately or off the record, now admit they expect a global temperature rise of 3°C to 4°C, or even higher, before the end of this century. (See https://climatejustice.social/@breadandcircuses/109642315870697356) And nearly all scientists agree that once levels that high are reached, additional tipping points and cascading effects will continue to make temperatures climb, probably for centuries more.
A few observers can still be found assuring us that while a “temporary overshoot” beyond 1.5°C might occur, it won’t last because, um, because magic will happen!
Although that's not quite what they say, it's almost as bad since they’re asking us to depend on carbon dioxide removal (CDR), a hopeful fantasy that we can someday cheaply and effectively remove gigantic amounts of carbon from the atmosphere and then put it *back* in the ground. Instead of, you know, just doing what we should have done in the first place — leave it *in* the ground!
David Ho, professor of oceanography at the University of Hawaii, published an essay this week in Nature that basically says what I just said, expect he backs it up with scientifically sound explanations and a very strong analogy.
TITLE & SUBTITLE: "Carbon dioxide removal is not a current climate solution. Drastically reduce emissions first, or carbon dioxide removal will be next to useless."

Attached: 1 image 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. #ClimateCrisis https://www.nature.com/articles/d41586-021-02990-w
