An "oldie" (2019 paper) but a real baddie - the danger of #clouds, particularly #stratocumulus clouds in the #subtropics, disappearing (!), is real, and really frightening. According to the most accurate (and afaik only) modeling done about this, if #CO2 reaches 1200 ppm - which it is predicted to do by mainstream #climate models in 100 years - a #TippingPoint will be crossed, stratocumulus clouds will disappear, and average #temperatures will rise by 10C in the subtropics and 8C in the #tropics. In other words, #Earth, as a livable planet for most species. will be done and dusted.

Prof. Sabine Hossenfelder ( @skdh physics prof., science communicator) is discussing this (possibly this same paper) in a recent video and putting it into context. Eight minutes (that's minus the sponsored section at the end) worth your time if you are interested in this. She's offering an imho pretty realistic scientific evaluation and scenario of what this might mean for us.
