A social awareness poster for global warming. The polar bear has become a martyr of sorts for the global warming initiative. As such, impalement is an ideal representation of the torture and execution polar bears face both literally and figuratively. Impalement is a specific torture designed to bring extended suffering before death. Imagine a polar bear swimming until drowning because the distance is too great between glaciers due to melting. To deepen the symbolism, the polar bear is impaled by the "north pole" which doubles as a mercury thermometer; bursting as a result of the extreme temperature.
