The Northern Sea Route passes from the North Sea to the Pacific Ocean along the coast of Russia.
It is now blocked with 3+ meter (10 feet) thick sea ice, shown as yellow and red in the map below from the Danish Meteorological Institute (DMI.)

DMI has records for 15 years, going back to 2004. The only other year out of the last fifteen which had ice this thick blocking the Northern Passage was 2010. But 2010 was less problematic because the thick ice was at a lower latitude where the ice normally melts during the summer. The animation below shows all 15 years.
Russia is building three nuclear icebreakers to allow commerce through this ten-foot thick ice. Good luck with that!

So much for Global Warming/Climate Change looks like Al Bore is wrong again but too darn dumb to know that
