The Guardian view on the Arctic: threatened by Putin’s war | Editorial

Geopolitical fallout from the conflict in Ukraine is threatening an environmentally crucial region

As the cold war thawed in the 1980s, the frozen high north of the planet was a leading beneficiary of more conciliatory times. Speaking in Murmansk in 1987, Mikhail Gorbachev called for an end to military competition in the Arctic, and a new focus on preserving its unique ecosystem. The community and interrelationship of the interests of our entire world," said the Soviet leader, is felt in the northern part of the globe, in the Arctic, perhaps more than anywhere else."

Mr Gorbachev's words paved the way for a cross-state consensus around the idea of Arctic exceptionalism" - an agreement that in an environmentally crucial region, where Europe, North America and Asia meet, geopolitical rivalries should be put to one side. Since 1996, the Arctic Council, comprising the eight Arctic states including Russia, has embodied that spirit of cooperation. It is yet another disastrous consequence of Vladimir Putin's war in Ukraine that it is now at risk.
