“Allocating a 2° C cumulative carbon budget to countries”: Gignac and Matthews
Abstract Recent estimates of the global carbon budget, or allowable cumulative CO2 emissions consistent with a given level of climate warming, have the potential to inform climate mitigation policy discussions aimed at maintaining global temperatures below 2° C. This raises … Continue reading
