Alaskan rivers turning orange due to climate change, study finds

As frozen ground below the surface melts, exposed minerals such as iron are giving streams a rusty color that pose a risk to wildlife

Dozens of rivers and streams in Alaska are turning rusty orange, a likely consequence of thawing permafrost, a new study finds.

The Arctic is the fastest-warming region in the globe, and as the frozen ground below the surface melts, minerals once locked away in that soil are now seeping into waterways.
