Assessing the size and uncertainty of remaining carbon budgets

Nature Climate Change, Published online: 30 October 2023; doi:10.1038/s41558-023-01848-5

The remaining carbon budget (RCB) is a critical estimate of the carbon that can be emitted while staying within a particular temperature threshold. This study provides an updated assessment of the RCB using recent data and robustness checks to increase confidence in the estimate.
