Global Warming Effect on Polar Bears

Now I've heard it all. Polar bear penis bones (sic) are shrinking in Eastern Greenland, according to the University of Aarhus in Denmark. It found that polar bears living in the Eastern Greenland are somewhat less well endowed than their cousins in Svalbard and the Canadian Arctic. They say this could be due to the high prevalence of pollutants such as PCBs and DDT in Eastern Greenland - pollutants which records show are less prevalent in Svalbard and the Canadian Arctic.

The study showed that carnivores living in snowy environments, close to the poles, tend to have longer penis bones to help them be more competitive. The group concludes that human pollution, combined with the difficulty of finding food in warming climates, may spell disaster for Eastern Greenland polar bears. Wonder how they get close enough to measure them.
