This summer, Arctic sea ice decreased to a its minimum extent on September 11, 2024. According to the National Snow and Ice Data Center this is the 7th lowest in the satellite record). The decline continues the long-term trend of shrinking ice cover in the Arctic Ocean. Each year, Arctic sea ice melts and refreezes with seasonal changes.
For 46 years, satellites have been monitoring changes in Arctic sea ice. This long-term data has helped scientists understand how polar environments respond to rising temperatures and extended melting seasons. Meanwhile, Antarctic sea ice is approaching its maximum extent for the year, with some time still remaining in the growth season.
