I am reading and quoting your very words.
> The polar bear population has steadily been increasing since the 1960s. Basically double what it was.
Then:
> You will find that the population has been stable globally.
Can you resolve the apparent conflict between these two statements?
Read the words before the second part:
"""
Go look at the data yourself: [link]
You will find that the population has been stable globally [...]
"""
I am summarizing their own analysis. If you go look in the data, you will see that the global population is on the rise.
