Suppose a planet exists with the same atmospheric composition as the Earth. On that planet, atmospheric CO₂ concentration rose from 200 to 600 ppm over 100 years, then net emissions fell to  less than  zero  (and turned into a strong net sink) . What would that planet's atmosphere?

Accepted Answer

It will take centuries for the CO 2  levels to stabilise on that planet

Answer

The planet’s surface got 30 °C warmer than before

Answer

CO 2  levels stabilise as soon as emissions stop

Answer
