"For limiting warming to 2°C with 66% or 90% probability, the RCBs are estimated at 940 and 500 GtCO2, respectively. With 40 GtCO2 emitted in 2022, this is roughly equivalent to 23 and 12 years of current CO2 emissions for a 66% or 90% chance, respectively, of limiting warming to 2 °C and 6 years of emissions for a 50% chance of 1.5 °C."
