Thawing Permafrost Turns Alaska's Rivers Orange, Raising Environmental Concerns

Scientists link the unusual coloration to the release of metals from thawing permafrost, posing risks to drinking water and aquatic life.

Researchers have identified 75 locations in Alaska's Brooks Range where rivers and streams are turning orange due to thawing permafrost.
The phenomenon is linked to the release of minerals and metals like iron, zinc, and copper, causing increased water acidity.
The color change, visible from space, has significant implications for drinking water and fisheries in Arctic watersheds.
The issue has been documented since 2008 and is expected to worsen with continued climate warming.
Scientists are conducting a three-year study to understand the full impact and potential recovery of these water systems.
