Climate change pushes orcas to migrate further north | The Independent Barents Observer

Warmer Arctic waters with less sea ice cause orcas to impact the northern marine ecosystems as the impressive whales swim further and further north in search of food and cooler temperatures.

Orcas are efficient hunters. Ecosystems that have not included orcas are devastated by their presence as they prey on fish and sea mammals.

30–50% of critical northern infrastructure could be at high risk by 2050 due to warming, says study | The Independent Barents Observer

About 500 Arctic villages and cities are located in areas where permafrost is expected to thaw by the middle of this century”, Miska Luoto, a professor at the department of Geosciences and Geography at the University of Helsinki in Finland, and one of the study’s authors, said in a news release.

Then collapse of the Arctic affects not only Arctic industries and municipalities, but the rest of the globe. The loss of glacial ice means sea level rise and dilution of salinity. Loss of fauna affects ecosystems. Loss of sea life affects other fishing industries. Loss of habitat drives animals to extinction or to relocate into human inhabited areas.

I have said this for at least a decade. Native land keepers and guardians know much more about the rhythm of the environment because they have generations of knowledge and a need to reserve their resources. Western wildfires would have been controlled sooner if native groups had been consulted. Balances of forest and field would be maintained. The necessary types of wildlife and water life would be preserved.
