Regional winds can temporarily mask the global thinning of Arctic sea ice
While Arctic sea ice is steadily declining due to rising temperatures, shifting weather patterns and cold northerly winds can create temporary increases in local ice coverage that disguise the broader trend of global thinning.
Arctic sea ice reached a seasonal maximum of 13,757,000 square kilometers in March 2026, continuing a 12 percent decline in average annual extent since the late 1970s. Despite this overall loss, regional wind patterns can create deceptive local anomalies. In the Bering Sea, cold northerly winds pushed ice levels to their highest point since 2013, even as the Sea of Okhotsk hit record lows due to persistent high-pressure systems.
