Rivers in Alaska are turning orange. It's an ‘unexpected consequence of climate change'

Rivers and streams in Alaska are changing color due to toxic metals released by thawing permafrost, according to a new study. The researchers conducted tests at various locations in Alaska’s Brooks Range and found that the waterways appeared rusty and cloudy over the past five to 10 years. Metals such as iron, zinc, copper, nickel, and lead were responsible for the discoloration and cloudiness, posing a threat to river and stream ecosystems. The accelerated thawing of permafrost in the Arctic, caused by climate change, is behind this unexpected consequence. The phenomenon has also been observed in other regions, including the Rocky Mountains in Colorado. The impact on aquatic and human life, as well as fishing and drinking water sources, is a growing concern. Further studies will be conducted to determine the sources of the metals and minerals and their effects on the environment.
