The Arctic is Full of Toxic Mercury, and Climate Change is Going To Release it (washingtonpost.com)

We already knew that thawing Arctic permafrost would release powerful greenhouse gases. On Monday, scientists revealed it could also release massive amounts of mercury -- a potent neurotoxin and serious threat to human health. From a report: Permafrost, the Arctic's frozen soil, acts as a massive ice trap that keeps carbon stuck in the ground and out of the atmosphere -- where, if released as carbon dioxide, the greenhouse gas would drive global warming. But as humans warm the climate, they risk thawing that permafrost and releasing that carbon, with microbial organisms becoming more active and breaking down the ancient plant life that had previously been preserved in the frozen earth. That would further worsen global warming, further thawing the Arctic -- and so on. That cycle would be scary enough, but U.S. government scientists on Monday revealed that the permafrost also contains large volumes of mercury, a toxic element humans have already been pumping into the air by burning coal. There are 32 million gallons worth of mercury, or the equivalent of 50 Olympic swimming pools, trapped in the permafrost, the scientists wrote in a study published in the journal Geophysical Research Letters. For context, that's "twice as much mercury as the rest of all soils, the atmosphere, and ocean combined," they wrote.

  1. And how did it get there? by bickerdyke · · Score: 1, Troll

    OK, 50 olympic pools of mercury sounds pretty dangerous. If someone dropped 50 pools of mercury somewhere, this definitly would be dangerous. But then again: How did it get there? Why concentrated in the arctic? I'm pretty sure no one disposed the worlds obsolete mercury thermometers there, so... coal burning? How many coal was burned in the arctic? Probably not much compared to past and modern industrial centers.

    So I'm setting up this hypothesis: If coal burning is the main source of mercury, the arctic received much less of mercury than any other part of the world. Only due to the climatic situation there, it was trapped in the ice. But then, even tose 50 pools can only be a fraction of mercury pollution compared to the rest of the world.

    Panic and crises are whole industries in and of themselves, pretty easy to see why.

    They lost me right there. Which may well mean they don't care about enlightening anyone, WaPo seems to write primarily to rile their base of paying supporters. It's a good business model and it lets them vent their desires for spiteful revenge so how could they resist it.

    I'll wait for another source.

    The world does not only consist of misinformed, Faux News watching, American Trump worshippers.

    Have some sympathy for the rest of us.
