Antarctic Sea Ice Rebounds Toward Average in 2026
Antarctic sea ice coverage has rebounded in 2026, nearing long‑term summer averages after four years of extreme lows driven by storms and warming seas.
Scientists at the National Snow and Ice Data Center report that Antarctic sea ice likely reached its annual summer minimum around late February 2026, at about 2.58 million square kilometers, the 16th smallest on record since 1979. This extent is still below the 1981–2010 average but significantly above the record low set in 2023. The partial recovery follows several years of unusually low ice cover linked to strong Southern Ocean storms and warm subsurface waters that eroded a protective cold layer beneath the ice. In early 2026, persistent southward winds in the Weddell Sea pushed ice outward, slowing its summer melt and helping preserve more area than in recent years. Researchers caution that year‑to‑year variability remains high and continued warming could rapidly reverse the trend.
