Arctic sea-ice extent has been decreasing steadily. During the last 30 years, satellites observing the Arctic have witnessed a halving of the minimum ice extent at the end of summer. Observations from space greatly assist in understanding and managing climate change. Measurements over long periods provide a reliable long-term record of Earth’s climate and improve our understanding of the changing planet.
