Summer sea ice loss is finally ramping up: first year is disappearing, as it has done every year since ice came to the Arctic millions of years ago.

SEA ICE BACKGROUND: EXTENT OVER THE LAST YEAR
Summer sea ice minimum 2018 (from NSIDC):
Winter sea ice maximum 2019:
Sea ice at 7 July 2019: early summer extent
Despite the fact that 2019 had the 2nd lowest extent for the month of June since 1979, by early July, there was still ice adjacent to all major polar bear denning areas across the Arctic. In many regions, pregnant females that give birth on land in December come ashore in summer and stay until their newborn cubs are old enough to return with them to the ice the following spring.
