Atmosphere may be more sensitive to greenhouse gasses when it is warmer. Makes sense to me. Possible 7C temperature rise by 2100. Which would bring 20m or so sea level rise with it. If we don’t stop air-dumping carbon now.

“In a paper in the journal Science Advances, they said the actual range could be between 4.78C to 7.36C by 2100, based on one set of calculations.”
