Bern Model when emissions stabilised at 2013 levels

The Bern model has been used by IPCC for emission scenarios since SAR in 1995. We will now use it to extrapolate CO2 levels 500 years into the future with annual emissions fixed at 2013 levels (~10 GT C/year). All values are expressed … Continue reading

A realistic CO2 stabilisation scenario

This is a guest post by “Frank” based on his comment to  Stabilising Climate. He argues that CO2 levels will stabilise at ~520 ppm, which agrees with an estimate given by Ferdinand  Engelbeen here quoted below: My rough estimate is that with the current emissions … Continue reading

Simple Model for rebalancing stable CO2 emissions

As requested by @richardbetts and @edhawkins here is a simple model to back up the arguments from the previous post – Stabilising Climate. Simple Model CO2 levels rise when the rate of change of the sources – S exceeds the rate … Continue reading
