When only higher-confidence net-zero targets are included on top of current policies (case B), global warming is projected to increase to 2.4°C by 2100 (range due to emissions projection uncertainties: 1.7° to 3.0°C) - missing global climate goals by a long way. INSIGHTS Clobal climate policy is undergoing a rite of passage. Global warming projections mirror this uncertainty, with best-estimate emissions leading to a median temperature projection for the year 2100 of 2.6°C, with a range of 1.7° to 3.0°C, depending on how policies are assumed to continue after 2030 (see the figure) (table S6).
