Candid images of fat, healthy bears taken over the last two years by unbiased photographers across the Arctic are representative of the state of polar bears in a world that’s warmer than it was in 1980.

It may seem counter-intuitive but it’s true: polar bears are thriving with less summer sea ice and there are more bears now than there were in 2005 (not a statistically significant amount more, but more nevertheless).

Starvation due to natural causes is the leading cause of death for polar bears and loss of body condition (getting thinner) is therefore the first symptom of impending death for virtually all polar bears that die naturally. However, polar bear specialist Andrew Derocher claims that loss of body condition is also the first symptom of climate change for polar bears.
But how do you tell the difference between polar bears made thin by man-made climate change and those who are thin due to natural causes?
You can’t. Even a necropsy will not be conclusive because there are so many natural reasons for a bear to lose weight — and even starve to death — that’s it’s virtually impossible to say that any thin bear is skinny due to a lack of sea ice.
Emaciated polar bears like the one above from Somerset Island in the Canadian Arctic,1 captured on camera in August 2017, are being used to promote the idea that polar bears are already dying of starvation due to climate change. That’s a big white lie, as the headline above suggests: seven months later, National Geographic has admitted as much. Here I show why it could not have been true in the first place (with references from the scientific literature).
