New study: Data reveals CO2 residence time is 3-7 years. 90% of human emissions since 1750 have thus already been removed, precluding a human-CO2-driven climate. But the UN IPCC uses model assumptions to claim CO2 residence time is over 100 years

New study:

Per empirical data CO2 residence time is 3-7 years. 90% of human emissions since 1750 have thus already been removed, precluding a human-CO2-driven climate.

The IPCC consequently uses model assumptions to claim residence time is >100 years. https://t.co/Cle5jtz1rf pic.twitter.com/KuUkeq737g
