Legacy industrial contamination in the Arctic permafrost: When permafrost thaws, the Arctic could face massive problems from legacy industrial contamination and pollutants

A previously underestimated risk lurks in the frozen soil of the Arctic. When the ground thaws and becomes unstable in response to climate change, it can lead to the collapse of industrial infrastructure, and in turn to the increased release of pollutants. Moreover, contaminations already present will be able to more easily spread throughout ecosystems. According to new findings, there are at least 13,000 to 20,000 contaminated sites in the Arctic that could pose a serious risk in the future.
