Polar bears became the poster child for the peril of climate change for obvious reasons: They hunt seals from the ice, and as fossil fuels warm the planet, the ice where these bears live is melting.

For more than three decades, scientists have been warning that climate change could drive polar bear populations extinct. That message infiltrated the public psyche, perhaps more than any other about the scourge of global warming.

But as scientists are continuing to learn, the reality for these iconic bears is more complicated.

In 2022, scientists published a study showing that polar bears in southeastern Greenland were able to use glacial ice instead of sea ice to hunt, sheltering them from some of the impacts of warming. And a study published late last year revealed some changes in polar bear DNA that may help them adapt to hotter weather.

“There’s variability in how bears are responding. This [research] adds to the variability story.”

Now, research in the journal Scientific Reports adds yet another wrinkle of hope for the species. The study, an analysis of hundreds of polar bears in the Norwegian archipelago of Svalbard, found that declining sea ice is not causing polar bears to starve. They actually appeared healthier in the last two decades of the analysis, from 2000 to 2019. The overall population, meanwhile, is either stable or growing, according to Jon Aars, the study’s lead author and a scientist at the Norwegian Polar........
