The Thawing Of Permafrost Due To Climate Change Has Caused Dozens Of Rivers In Alaska To Suddenly Turn Orange, Threatening Local Wildlife Populations

For instance, at a tributary of the Akillik River, researchers documented the loss of two fish species, Dolly Varden and Slimy Sculpin.

The metals in the river can accumulate in fish gills, livers, and muscle tissue, which inhibits growth and damages DNA.

Humans living in Alaska may also feel the harmful effects of the orange rivers. Rural communities have the potential of losing access to sources of drinking water as the permafrost continues to melt.

The researchers hope this study will lead to response efforts to address the issue before more wildlife is lost.
