Climate change is turning northern lakes brown and starving them of key nutrients

A new analysis of northern lakes reveals that rising temperatures and shifting precipitation are darkening waters, depleting nutrients, and creating nitrogen shortages—changes that threaten both freshwater ecosystems and the fish stocks and water supplies that depend on them. The findings suggest policymakers need to rethink water management strategies across Arctic and subarctic regions.
