A story prominently displayed on the Science News headlines at Yahoo! News on Friday came from LiveScience.com, which used this question as its headline: "Is Global Warming Driving Polar Bears to Cannibalism?" and later in the article, after asking the question "are polar bears more often resorting to cannibalism because of increased hunger and desperation, or are we simply more frequently observing a behavior that has always existed?" they proceeded to address the cannibalism side of the question without even considering the idea that this behavior might indeed be normal for polar bears.
After asking what was causing the polar bears' descent to cannibalism, the article proceeded to state that the answer to the question would "reveal whether or not the Svalbard polar bear population has started to feel the heat from climate change." In other words, the writer suggested the probability that young polar bear cubs being cannibalized by adult polar bears has been caused by people being unsafe with their car's emissions or overusing their barbecue pit.
