Polar bear habitat update: Labrador sea ice highest in 20 years

Sea ice off the southern Labrador coast hasn’t been this high for this date in 20 years: that’s great news for the harp and hooded seals that will give birth at the Front in another few weeks – for a while anyway, because a bumper crop of baby seals is also good news for the polar bears who gather there to eat them.

So brutal, but true. The polar bear must gorge over the short Arctic spring and early summer to survive the rest of the year.

Today (day 56, 2016), the NSIDC MAISE ice chart shows 15.0 mkm2 of sea ice.

Sea ice is low in the Barents Sea but it was almost as low for this date back in 2012 but a 2015 survey showed Svalbard polar bears not only survived, they were in good condition and their numbers had grown by 42% over the count done in 2004.
