Figure

Observed and projected decline in Arctic sea-ice area

This figure combines two data sources. The left part shows the observed change in Arctic sea ice are (individual observations and trend lines) over the period 1979 to 2021 for March (maximum ice cover) and September (minimum ice cover). The right part shows projections of Arctic sea ice area in March and September from CMIP6 simulations for three emissions scenarios. The thick lines denote the multimodel ensemble mean (24-27 models, depending on the scenario), and the shading shows the likely uncertainty interval (one standard deviation around the multimodel mean). The dashed line indicates a threshold for near ice-free conditions."
