Watch the Arctic’s sea ice slowly disappear

and depicted above, , on average, by more than one-third from 1984 through 2018. Only in two portions of the last ice areaone patch immediately north of Greenland, and another swath centered more than 1300 kilometers to the west along Canadas northernmost islandsdoes near-total sea-ice coverage persist from year to year, the researchers say.

Unlike the rest of the Arctic Ocean, ice thicknesses in these two regions range up to a maximum of 4 meters or so. But the teams new analysis also reveals that ice loss there is occurring at twice the rate it is elsewhere in the Arctic Ocean. These two areas of persistent (for now) sea ice may be the final northern realms where wildlife largely dependent on sea ice for survival, such as polar bears, walrus, and narwhals, can hold out in a warming world, the scientists say.
