Rivers in the Arctic are exhibiting a striking orange hue due to the thawing of permafrost in regions like the Brooks Range. This phenomenon, known as 'rusting rivers,' occurs as melting permafrost releases iron and other metals into waterways, causing discoloration and raising concerns about ecological impacts. Climate change is a significant driver, accelerating the release of metal-laden sediments and altering water chemistry, which affects aquatic life and the broader environment.
