Fallout from humanity’s nuclear legacy is locked in glaciers around the world, and now scientists are worrying that it may seep into the environment as climate change causes Arctic ice to melt.

This apocalyptic scenario was explored by an international team of scientists who looked at the spread of radioactive contaminants in Arctic glaciers throughout Sweden, Iceland, Greenland, the Norwegian archipelago Svalbard, the European Alps, the Caucasus, British Columbia, and Antarctica. The researchers shared their results at the 2019 General Assembly of the European Geosciences Union (EGU) in Vienna last week.
