Sabine Hossenfelder explains how the greenhouse effect actually works, given that infrared is mostly absorbed low in the atmosphere already. She walks through why more CO2 still warms the surface.

Recommended as an accessible, nuanced explanation of the mechanics of global warming, including the saturation puzzle.

For anyone who's curious, here's an explanation of how the greenhouse effect works -- it's not just that some infrared radiation escapes from earth to space, while some other infrared radiation gets trapped. ▶ this video

This is good news, somehow. Here is how the earth 'greenhouse effect' really works: ▶ this video This is why Co2 do not have any effect until it reaches the high troposphere. That takes 20 years. The average climate we have right now is caused by emissions from 2003. I'll repeat that in the comments of every climate article I read by the way, sorry for the repetition. M
