David Attenborough and his cronies at Netflix devoted an entire documentary last year (‘Breaking Boundaries‘) on the nonsense notion that the world is facing a dire ‘tipping point’ where calamity is inevitable, with the Arctic being ‘Ground Zero’ for these effects. However, their sea ice model has already been falsified by the last seven years of data.

All predictions of disaster aside, in fact the polar bear is no closer to extinction than it was in 2005 as Arctic sea ice again steadfastly resists slipping past a catastrophic ‘tipping point’ — or the ‘death spiral’, as some chicken-littles continue to call it.
In fact, the summer sea ice trend has been pretty much flat since 2007, with ice covering about 42% less area than it had done in 1979, yet polar bears in many regions are doing better now than they were in 2005, especially in Davis Strait, the Barents and Chukchi Seas and the Canadian Arctic Archipelago.

This year near the end of May the distribution of thickest sea ice (3.5-5m/11.5-16.4 ft – or more) is a bit surprising, given that the WMO has suggested we may be only five years away from a “dangerous tipping point” in global temperatures. There is the usual and expected band of thick ice in the Arctic Ocean across northern Greenland and Canada’s most northern islands but there are also some patches in the peripheral seas (especially north of Svalbard, southeast Greenland, Foxe Basin, Hudson Strait, Chukchi Sea, Laptev Sea). This is plenty of sea ice for polar bear hunting at this time of year (mating season is pretty much over) and that thick ice will provide summer habitat for bears that choose to stay on the ice during the low-ice season: not even close to an emergency for polar bears.
