There are thousands of contaminated sites in the Arctic, and as permafrost thaws, increased pollutants from these areas could be released, says a recent study.

Temperatures are rising twice as fast in the Arctic region as in the rest of the world—a crisis that has rendered the area a laboratory for global cooperation and the transition to more sustainable practices.
In a new study, researchers at Dalhousie University have found that sea-level rise is causing permafrost along Arctic coastlines "to thaw and retreat," threatening northern ecosystems.
After a hard winter with a heavy COVID-19 toll in rural Alaska, health officials called for sweeping action to bring water and sanitation services to predominantly Native villages that have long lacked them.
