ICYMI: In an Arctic reshaped by the climate crisis, less ice really means more as countries face risks in push for more ships
For millennia, a mass of sea ice in the high Arctic has changed with the seasons, casting off its outer layer in summer and expanding in winter as it spins between Russia, Canada and Alaska. Known as the Beaufort Gyre, this fluke of geography and oceanography was once a proving ground for ice to “mature” into thick sheets.
