David Craig, on March 29th, 2013Here’s a photo of a polar bear apparently stranded on a tiny ice floe due to man-made global warming melting Arctic ice:
This is the kind of photo ecofascists tend to use to warn us about the destructive results of their supposed “man-made global warming”.
And here’s a table showing the frightening decline in polar bear numbers due to man-made global warming. Whoops, sorry. Polar bears are thriving. Their population has shot up from somewhere around 5,000 in the 1950s to above 25,000 by 2005. Some experts even think there may now be 32,000 polar bears
And here are 10 reasons not to worry about the survival of polar bears.

In fact, the most drastic declines in polar bear numbers have been due, not to melting ice, but during periods when there was too much ice preventing them reaching their main food source – seals. And some experts believe the biggest threat to polar bears now is that there are too many all competing for the same food resources.
If the ever-increasing number of polar bears knew that all the handwringing, bleeding heart, misguided ecofascist greenies were predicting their imminent disappearance, I imagine they’d be rather surprised.

This is rubbish! You need to look at the details to understand declines and increases.
In truth, Polar bears have an unnaturally low population throughout most of their range due to the actions of Man (not just global warming affecting ice cover but also hunting, pollution, food depletion, etc.). Yes, many of the ‘brown sandal brigade’ do go over the top on occasions but that shouldn’t blind anyone to the facts.
An example of ignoring the truth are the qoutes that Polar Bears are doing wonderfully well in the Davis Strait so surely the lack of ice cover isn’t a problem. Yes, there has been a big increase. However, I personally know this was the consequence of the EU banned the import of Harp Seal pup skins which lead to a decline in seal pup hunting. This lead to an increase in the seal population (which was unnaturally low) and subsequently an increase in their principle predator the Polar Bear (whose population was also unnaturally low). The population is now estimated to be over 2,000. The increase does NOT show that the Polar Bear does not need sea ice. Indeed, one could rightly ask the question, would the bear population be higher if the ice cover was normal?
Likewise, local declines may not be caused by the lateness of ice cover leading to bears starving because they can’t access their prey. There may be other factors involved such as over-hunting.
The truth is no-one really knows how the decrease in Arctic ice will affect the Polar Bear. What we do know is that many Polar Bear subpopulations require sea ice to get access to their principle (and most freely available) prey, the seal and there is a direct correlation between warm years and starving bears. The warm events are likely to continue and increase in number (indeed, 2014 is set to be the warmest year on record). For this reason the conservation status of the species was changed from ‘Least Concern’ to ‘Vulnerable’ by the IUCN in 2006.
To say the Polar Bear is safe from extinction is more mind-numbingly ignorant than saying that the species will be extinct by the end of the decade. The bear won’t become extinct by the end of the decade but it will be adversely affected!!
Here’s a link which gives a better balanced picture of the story. http://www.canadiangeographic.ca/magazine/dec12/polar_bears.asp
I agree with S Richards, One cannot only examine one piece of evidence and make an assumption. The truth is there was thought to be such a low amount of polar bears before is because the methods used to measure the amount was inefficient.
David Craig, you disgust me that you do not believe in something so blatantly obvious. Global warming is not a theory, it is a proven fact. The polar ice caps are projected to disappear completely which means there will literally be no more polar bears. Please get this through your ignorant head that there needs to be a change in our lifestyles.
