Melting permafrost is releasing sulfide minerals into rivers, causing a chemical reaction that turns the water orange.
These changes threaten aquatic health and could impact rural communities dependent on subsistence fishing.
Researchers identified 75 affected rivers, noting high metal content and acidity in the water.
Key quote:
“It’s really disturbing to see this kind of rapid change associated with climate change. It’s a call to action for the entire state.”

Why this matters:
The phenomenon highlights the broader impacts of climate change on vital natural resources. This could disrupt the livelihoods of rural Alaskan communities and the state's significant fishing industry, heightening the urgency for climate action.
The U.S. Bureau of Indian Affairs will grant three tribes $25 million each to relocate homes, schools, and critical infrastructure. These are the first grants distributed under a program aimed at helping tribes cope with climate change.
