According to climate change enthusiasts, warming temperatures are melting the arctic ice, reducing the habitat of the polar bears and causing a decline in their numbers. There are only two problems with this claim: the arctic ice cap is growing, and so is the polar bear population.
According to Polar Bear International, a conservation group focusing on polar bears:
Polar bears have evolved for a life on the sea ice, which they rely on for reaching their seal prey. But the arctic sea ice is rapidly diminishing due to a warming earth, affecting the entire arctic ecosystem, from copepods to seals to walruses. For polar bears, sea ice losses mean;
- Reduced access to food
- Drop in body condition
- Lower cub survival rates
- Increase in drowning
- Increase in cannibalism
- Loss of access to denning areas
Scientists predict that as the Arctic continues to warm, two-thirds of the world's polar bears could disappear within this century.
If they checked out the science rather than listen to the idle warnings of the climate change community, Polar Bear International would feel much better about the future of their furry white friends.
Based on the graph below, dated 12/18/15 and published on the Real Science blog, but created by the Danish Meteorological Institute (which is run by the Danish Government), the Arctic sea ice extent (the area of the sea covered by ice) this year is larger than it's been since 2004.
Additionally, University of Alabama Huntsville satellite data for November (the latest of their monthly releases) reveal that temperatures in the northern hemisphere have shown a zero or negative trend (defined as from zero increase to an increase at a rate of less than .01 degrees centigrade in a century).
As for the claim of a polar bear-free world, it seems that no one checked with the bears - because their population is growing. The climate science website Watts Up With That reported growth in one particular region:
Results of this fall’s Barents Sea population survey have been released by the Norwegian Polar Institute and they are phenomenal: despite several years with poor ice conditions, there are more bears now (~975) than there were in 2004 (~685) around Svalbard (a 30% increase) and the bears were in good condition.

Oddly, in a September report right after the count, biologist Jon Aars reported them in “excellent” condition, with some of them “as fat as pigs.” I guess “good” is the same as “excellent.”
Bears in the Russian portion of the Barents Sea were not counted this year because the Russians would not allow it; the previous total count, from 2004, was 2,650 (range ~1900-3600) for the entire region.
Interestingly, tracking the world-wide population of polar bears has been difficult because the International Union for Conservation of Nature (IUC), which provides the "official numbers," changed their method of reporting in 2015 after years of increases. The change makes demonstrating a trend up or down impossible. The site Polar Bear Science, which has been reporting the IUC numbers, believes the reason for the methodology change was to hide increases in the polar bear population. Even so, based on the local data and what's been known through May of 2015, it looks as though the bear population is up.
Despite the fear tactics employed by the climate change community, the scientific evidence shows a rise in both the Arctic ice extent and the polar bear population. In other words, if polar bears could talk, they might very well echo the famous quote of Mark Twain:
"The reports of my death have been greatly exaggerated."
