New global warming worry – DDT

DDT and other toxins have accumulated for decades in the icecaps of Greenland and Antarctica. And global warming is new releasing some of this stew. Adélie penguins are being exposed, so far in trace amounts, in the Antarctic. Polar bears and other animals have already been exposed in Greenland, and Canada’s northernmost islands. So far, no worries there, either, but it is something to monitor, given the other threats to polar bear survival.
