New research shows that permafrost soils hold massive quantities of mercury — nearly twice as much as is held in all other soils in the world, plus the mercury in the oceans and the atmosphere —
Just what exactly is permafrost? And what is happening now that it's warming up? To find out, we enter the Arctic Circle's secret world of ice and frozen history.
