Climate change is NOT to blame for polar bears breeding with grizzly bears

Climate change is NOT to blame for polar bears breeding with grizzly bears

One of the many damaging effects of climate change put forward by scientists is that shrinking habitats are causing polar and grizzly bears to mate more.

This hybridisation could dilute polar bears’ DNA which will further drive down the animals’ already dwindling numbers, experts suggest.

But a new study reveals that this inter-breeding is natural and is in fact not a consequence of global warming.

One of the many damaging effects of climate change put forward by scientists is that shrinking habitats are causing polar and grizzly bears to mate more. Pizzly, grolars or 'cappuccino bears' are common names of grizzly/polar hybrids (pictured)

It had previously been assumed climate change causes grizzlies or ‘brown bears’ to invade northern regions while polar bears are pushed onto the sea ice later than usual.

The new results show however that an abundant flow of genes among different bear species occurred plenty of times in the past.

Polar Bears Are Fine – Except For the Hunting

Polar Bears are fine. Except for the ones shot by hunters and turned into pelts for rich Chinese.

… there are about 15,000 polar bears across Canada’s Arctic. “That’s likely the highest [population level] there has ever been.”

There’s much at stake in the debate. Population figures are used to calculate quotas for hunting, a lucrative industry for many northern communities. Hunting polar bears is highly regulated but Inuit communities can sell their quota to sport hunters, who must hunt with Inuit guides. A polar-bear hunting trip can cost up to $50,000. Demand for polar-bear fur is also soaring in places like China and Russia and prices for some pelts have doubled in the past couple of years, reaching as high as $15,000.

The Nunavut hunting quota in the western Hudson Bay area fell to 8 from 56 after the 2004 report from Environment Canada. The Nunavut government increased it slightly last year but faced a storm of protest. Over all, about 450 polar bears are killed annually across Nunavut. Mr. Gissing said a new quota is expected to be announced in June.

Polar Bears Are Morons (Maybe Not)

A study claims Polar Bears are swimming longer, tiring them out and that maybe cause them problems.

The Polar Bear Science Blog points out the obvious:

So, despite what may be implied during media moments, Beaufort Sea polar bears were  not frantically trying to reach the sea ice from land so that they could attempt to keep feeding over the summer – most of their swimming was done during breakup in July and August from one bit of pack ice to another and they showed no evidence of harm from doing so.

What do you think? Do you think they swim like this (avoiding all ice floes):

Or like this (jumping on ice floes for a rest when they need it):

Polar Bears in Southern Hudson Bay Losing Body Weight – Or Just Dying?

Capture A new “study” blames climate change for making Polar Bears in the southern Hudson Bay population lose weight .

The world’s southernmost population of polar bears has already lost significant amounts of body weight after decades of shrinking sea ice with breeding females suffering the most, says new research from the Ontario government.

“They’re in poorer condition now than they were in the 1980s,” said Martyn Obbard, of the province’s natural resources department, one of the co-authors of the paper published by the National Research Council.

Maybe it isn’t climate change. Maybe the biggest polar bears are being shot.

Northern wildlife officials will meet in Quebec’s arctic region Wednesday to discuss quotas on the world’s last unregulated polar bear hunt.

Hunters who kill bears from the south Hudson Bay population, which includes Quebec, Ontario and Nunavut, have a voluntary limit of 60 bears a year.

But scientists say climate change is starting to affect the population’s health and that the region’s first official quotas should be lower.

None of the various aboriginal communities that hunt those bears say they’re willing to reduce their take.

According to the first report, there are “roughly 900 bears” in the southern Hudson Bay population. If you kill at least 60 (it is after all a voluntary quota) out of 900 and if you are selling those pelts you want the biggest and healthiest bears.

Maybe the survivors (after the biggest are killed for their pelts) are smaller.

Bids for what ended up being the dearest skin, a spotless white specimen that was also over 10 feet in length, started at $7,000 and didn’t stop until they’d reached $12,400—$1,400 more than last year’s top seller, a previous record. It went to Anna and Steve Gao, whose Mississauga, Ont.-based business, Canadian Intertrade JJ Ltd., ships furs to China and elsewhere.

Early this year, word spread that hunters from the northern Quebec community of Inukjuak had killed as many as 70 polar bears last season—an enormous jump over past years and an unsustainable harvest rate for the southern Hudson Bay polar bear population

The spike in kills around Inukjuak is thought to have begun when a buyer arrived in the region and announced he’d pay big money in advance for furs.

If you look at Canada as a whole 500 polar bears are being shot:

Each year, Aboriginal hunters and foreign sportsmen pursuing the animals alongside Aboriginal guides kill some 500 polar bears (there is no federal cap, and that number depends on shifts in geographic harvest quotas and on First Nations treaties). Many of the resulting polar bear skins find their way to market.

 

IPCC admits: No evidence climate change has led to even a single species becoming extinct

Finally!!! Everytime I argue with members of the AGW Cult they claim we are in the midst of a “great extinction”. I ask them to name 10 species. When they can’t name any, I ask for 5. They usually come up with one animal that has been hunted to extinction (which is horrible, but not AGW)

Old Prediction:

“Global warming is said to be threatening thousands of animal and plant species with extinction. That, at least, is what the Intergovernmental Panel on Climate Change (IPCC) has been predicting for years.”

New Confession:

 IPCC admits that there is no evidence climate change has led to even a single species becoming extinct thus far.”

Polar Bears Are Doing Fine:

“At most, the draft report says, climate change may have played a role in the disappearance of a few amphibians, fresh water fish and mollusks. Yet even the icons of catastrophic global warming, the polar bears, are doing surprisingly well. Their population has remained stable despite the shrinking of the Arctic ice cap.”

Models Suck:

“”There is very little confidence that models currently predict extinction risk accurately,” the report notes. Very low extinction rates despite considerable climate variability during past hundreds of thousands of years have led to concern that “forecasts for very high extinction rates due entirely to climate change may be overestimated.””
