A new study by Canadian scientists once again debunks the notion polar bears are currently being harmed by global warming. Researchers with Canada’s Lakehead University found “no evidence” polar bears are currently threatened by warming.
“We see reason for concern, but find no reliable evidence to support the contention that polar bears are currently experiencing a climate crisis,” Canadian scientists wrote in their study, published in the journal Ecology and Evolution.
Scientists looked at 13 polar bear subpopulations and found “much of the scientific evidence indicating that some polar bear subpopulations are declining due to climate change-mediated sea ice reductions is likely flawed by poor mark–recapture sampling.” This means researchers aren’t able to put together accurate “demographic parameters.”
