At least from a birds eye view. Conditions on the surface might differ slightly.
Arctic sea ice
The northeast passage along Russia's northern coast is probably also soon to open.
For context, such openings never happened in human history before about 2001, and very likely had not happened for 9,000 years prior to that. Fossil and genetic evidence for migration of species between the Pacific and Atlantic via the Arctic indicates that such openings have been very rare for the past 800,000 years or so. Now it seems to be the new normal, happening sooner every year.
Some ships did manage to traverse it prior to 2001, but only with the assistance of ice-breakers, or by sailing partway over the ice, or by taking multiple years to complete a single passage. Now it's becoming possible for simple sailboats to breeze through in a few weeks.
For additional context, Arctic sea ice volume continues its death spiral towards zero ice: Arctic sea ice volume (yearly spiral)
