Satellites have provided a reliable tool for continuously monitoring changes in the Arctic ice since 1979. Every summer, the Arctic ice cap melts to what scientists call its "minimum" before colder weather begins to make ice cover increase.
This visualization shows the expanse of the annual minimum Arctic sea ice for each year from 1979 through 2022, with a graph overlay.
In 2022, Arctic minimum sea ice coverage tied for 10th-lowest on record, extending a long-term downward trend.
