global mean temperature  increase relative to an 1850-1900 baseline. For each data point, the study-specific GMT increase was calculated to show effectiveness at 1.5℃, 2ºC, 3°C and 4°C. Based on the ability of an implemented option to return the system to its baseline state, the effectiveness is classified based on the share of risk the option can reduce: large ; moderate ; small ; insufficient . Where the system state is improved relative to baseline, co-benefits are identified. Residual impacts show the share of remaining impacts after adaptation has been implemented: negligible ; small ; moderate ; large . Where risks increase after adaptation, data points are shown as maladaptation. All underlying data is provided in Table SM4.6.
