That is a very different claim than your original.

You said it is steadily increasing and has doubled.

And, yes, I read the whole article.

"'Populations have not grown,' Steven Amstrup, chief scientist for Polar Bears International, said in an email. 'Rather our growing knowledge has shown there may be more bears in these areas than we previously thought.'"

"The areas with the best data show no increase, contrary to the post's claim. According to the 2021 report, three of the subpopulations have decreased over the past two generations. None of the subpopulations have increased over the past two generations."
