  • Projections assume zero additional emissions after emissions end dates listed, except for the historical + EIEI scenario. EIEI is the expected future emissions implied by existing energy infrastructure, as estimated in ref. 23. The years shown relate to emissions and associated commitments, not to the timing of ensuing warming or SLR. Levels of committed warming and SLR associated with each scenario are shown in Table S1. US totals include only the listed states and the District of Columbia.
