This figure combines two data sources. The left part of the figure (black lines) shows the observed change in Arctic sea ice over the period 1979 to 2022 for March (maximum ice cover) and September (minimum ice cover) based on the EUMETSAT OSI SAF Sea Ice Index v2.1 dataset. The right part shows projections of the Arctic sea ice area in March and September from CMIP6 simulations for three emissions scenarios. The thick lines denote the multi-model ensemble mean (24-27 models, depending on the scenario), and the shading shows the likely uncertainty interval (one standard deviation around the multi-model mean). The dashed black line indicates a threshold for near ice-free conditions.
