Another sign of anthropogenic #climatechange unravelling our ecosystems.
Iron & other heavy metals are leaching out of the melting permafrost in Alaska & elsewhere in the Arctic & high mountains as they warm.
This turns the rivers red, acidifies them, pollutes the water, & breaks the food chain.
Deposits of metals that have taken millions of years to form disperse into the environment – the process is irreversible on human timescales.
We’re so frakked.
