In early December, a video of a dying, emaciated polar bear, foraging for food on an iceless land, went viral on social media. The video garnered millions of views on Facebook and YouTube. For most, it was a vivid signal of the future in store for us all due to human-caused (anthropogenic) global warming ― rising temperatures due to increased carbon dioxide, methane and other greenhouse gases. For those who deny or minimize the existence of anthropogenic global warming it wasn’t a polar bear, but a red herring (“Propaganda,” one YouTube viewer called it) — no one knows why it was dying, much less if it can be connected to global warming.
That’s true, but also a bit beside the point.
