Arctic rivers began to "rust":
"The waters of the Arctic rivers have begun to turn a bright orange hue, a phenomenon observed throughout the region - in Alaska, Canada and Siberia. Scientists are "amazed" by the scale of the changes and claim that humanity is currently unable to stop them. Water gets colored due to interaction with iron, usually it happens with wastewater in mines. However, in the Arctic, rivers are turning red due to global warming."
