>>Yay! Now all greenhouse emissions are eligible for massive regulation. How long until they start regulating the steam coming from my ears.

>You can debate the cause but it is a fact that the polar ice cap is melting, and that does represent a threat to polar bears. Hence being declared an endangered species.

There is no fixed ice cap in the Arctic, unlike the Antarctic, it is a sea that has ice on it, which changes dramatically throughout the year. The mechanisms behind those ice flows are numerous and not well understood. The goal in achieving the listing is to regulate carbon emissions, which means everything involving CO2, including our exhaled breath, is subject. There are multiple divergent studies regarding polar bear populations, nothing definitive. Finally they weren't listed "endangered" mearly "threatened", however, the resulting lawsuits will hardly care about the distinction.
