Wolfgang Lucht"We conclude that the RCB (Remaining Carbon Budget) for a 50% chance of keeping warming to 1.5 °C is around 250 GtCO2 as of Jan 2023, equal to around six years of current CO2 emissions. For a 50% chance of 2 °C the RCB is around 1,200 GtCO2."
An update to the IPCC's CO2 budgets, which are several years old, in terms of newer data and updated methods. NOT good news.
Follows a previous paper in ESSD by Forster et al. (2023) with comparable findings.
