A new look at the Arctic sea ice record reveals that the current ice cover is younger and thinner than at any time in the last 60 years. About 70 percent of Arctic sea ice is now seasonal, forming and melting within one single year. This thinner, younger ice is more susceptible to breakup and warmer temperatures. The record combines data from satellites and declassified submarine sonar measurements and stretches back to 1958. Since that time, Arctic sea ice cover has lost about two-thirds of its

Arctic sea ice appears to have hit its annual minimum extent on Sept. 16, at 4.72 million square kilometers (1.82 million square miles). This year's extent is the 12th lowest in the satellite record, according to scientists at NASA - National Aeronautics and Space Administration and National Snow and Ice Data Center: https://climate.nasa.gov/news/3114/nasa-finds-2021-arctic-summer-sea-ice-12th-lowest-on-record/ 🎥: NASA's Scientific Visualization Studio | NASA Climate Change

ICYMI: Earth’s sea ice reached a new low in 2025. 🌊🧊 Every year, sea ice cover in the Arctic grows in the dark and cold of the Northern Hemisphere winter, reaching its annual peak. Arctic sea ice hit its peak on March 22, 2025 at 5.53 million square miles (14.33 million square kilometers), making it the lowest annual peak on record. In the Antarctic, sea ice melts during the Southern Hemisphere summer to its annual minimum extent. This year, Antarctic sea ice retreated to 764,000 square miles

Sea ice update 🌊🧊 Global sea ice hit a record low this winter, NASA and the National Snow and Ice Data Center report. This year was the lowest Arctic sea ice maximum and the second-lowest Antarctic sea ice minimum. Sea ice forms and spreads across Arctic seas every winter. But in recent years, less new ice has been forming, and less multi-year ice has accumulated. Winter sea ice cover in the Arctic was the lowest it’s ever been at its annual peak on March 22, 2025, continuing a downward trend

Did you know that sea ice has an age? In this dataset, colors show the age of sea ice floating in the Arctic Ocean. The darkest blue areas on the map show seasonal or first-year ice, which formed during the most recent winter. White areas show where ice is more than four years old. Since the late 1900s, Arctic sea ice has thinned, and less sea ice has persisted in the Arctic over multiple melt seasons. The trend toward younger, thinner sea ice over time reflects warming temperatures in the Arcti
