From: No compromise in efficiency from the co-application of a marine and a terrestrial CDR method

(Top) For every Carbon Dioxide Removal (CDR) scenario the lineplots show the timeseries of the intermodel average difference in globally averaged 2 m temperature (°C) compared to the mean temperature under REF. The shading around the mean shows the minimum-maximum range across both models and all ensemble members. To aid interpretation, the boxplots on the right show yearly values of globally averaged temperature between 2090 and 2099 pooled from both models and all ensemble members. The whiskers show the 5th–95th percentiles of pooled values. The model-specific 2090–2099 averages are shown with the colored circles, and the intermodel average with the horizontal black lines. (Bottom) The maps show the intermodel average difference in average 2090–2099 2 m temperature (°C) between each CDR and the REF scenario. Stippling highlights statistical insignificant differences. Statistical significance is declared over gridcells where: (a) the two models agree on the sign of the change, and (b) at least one model shows a statistically significant difference at the 10% significance level based on a two-tailed Student’s t test adjusted to account for temporal lag-1 autocorrelation67. For each gridcell and model, the test is applied over the yearly data pooled together from all ensemble members for the given period.
