Arctic Sea Ice Hits Record Low in July
Polar bears encountered more open water than usual this July, with less ice available as seal-hunting grounds. According to a new report by the National Snow and Ice Data Center (NSIDC), Arctic sea ice coverage reached the lowest July extent since satellite-data records began, 21.6% below average.
The center also reported a greater loss of older, thicker sea ice, with a loss of 14% from March through July. The sea ice extent remained below normal everywhere in the Arctic except East Greenland.
