Despite what some climate-change deniers have claimed of late, polar bears are struggling to survive, as the planet warms.

An LA Times ran article on Saturday, reporting on a recent study that showed populations of polar bears in Alaska and western Canada fell by 40 percent, from 2001 to 2010. The research was conducted by scientists from a number of organizations, including the U.S. Geological Survey and Environment Canada.

As the report notes, hunting for food is much more difficult for the animals now. As the Arctic ice continues to dramatically melt, they are forced to swim greater distances between ice fields.

But some in the anti-science crowd continue to claim the ice is not melting and polar bears are healthy and happy. Just saying something that is not true over and over and over again doesn’t turn it into a fact.

It’s so sad to see entire species of majestic creatures slip into extinction, while the root causes are too largely ignored. Sometimes, as is the case with climate change, it is greed that drives the movement to ignore these issues.
