Newsbytes: Polar Bear Population Growing Despite Declining Sea Ice

Great News! But Where Is The News Coverage?

polarbear_billboard

From The GWPF and Dr. Benny Peiser

Exciting news about polar bears in eastern Canada: a new the peer-reviewed paper concludes that despite sea ice having declined since the 1970s, polar bear numbers in Davis Strait have not only increased to a greater density than other seasonal-ice subpopulations, but it may now have reached its ‘carrying capacity.’ This is great news. But where is the shouting from the roof-tops? This peer-reviewed paper was published February 19, 2013. No press release was issued that I could find and consequently, there was no news coverage. Funny, that. –Susan Crockford, Polar Bear Science, 10 June 2013

 

One of the interesting aspects of the current temperature standstill is that it persists despite several El Ninos and La Ninas. Since 2006 the influence of these events has been more pronounced in satellite data; El Ninos in 2007 and 2009-10, La Ninas in 2008, 2010–2012. These events have increased the ‘noise’ of the global temperature data in recent years. Removing this noise is tricky, but without it there is a hint, just a hint, that sans El Nino/La Nina effects and volcanic dips, the global temperature might be reducing. As usual, five more years of data will be fascinating to analyse. –David Whitehouse, The Global Warming Policy Foundation, 11 June 2013

Prof. Murry Salby, climate scientist at Macquarie University of Sydney, made a presentation in Hamburg on April 18th as part of a European tour. Prof. Salby is author of the textbook Physics of the Atmosphere and Climate (Cambridge University Press) and Fundamentals of Atmospheric Physics (Academic Press) and is renowned worldwide as an astrophysicist. He recently caused excitement with new findings on the relationship of the 12C- and 13C isotopes and the development of CO2-concentration. From the findings he concluded that the anthropogenic emissions only had a slight impact on the global CO2-concentrations. They are mainly a consequence of temperature changes. This relationship is known up to now only from the warming phases after the last ice ages. Prof. Salby extends this relationship to our current climate development. —Die kalte Sonne, 8 June 2013

I did a quick post yesterday on the May numbers on RSS [satellite data], which fell sharply to 0.139C. The RSS figures are anomalies from the 1979-98 baseline, and I pointed out that, against a baseline of 1981-2010, current temperatures are now only 0.039C higher. I also mentioned that the 1981-2010 average had been artificially depressed by the two eruptions, El Chichon in 1982 and Pinatubo in 1991. Take the two volcanoes out of the equation, and it is clear that there is nothing unusual about current temperatures. –Paul Homewood, Not a Lot Of People Know That, 8 June 2013

When the Little Ice Age caused widespread crop failures, mass starvation, and disease in populated Europe some centuries ago, the enlightened ones blamed the climate-related misery and misfortune on the black magic of sorcerers and witches – who were promptly tried and burned at the stake. In other cultures, people performed rain-dances, human sacrifices, or other bizarre rituals, all in a futile attempt to appease the weather gods. Of course the victims of these rituals were often political opponents. Today nothing has changed apparently, as Der Spiegel poignantly demonstrates with its latest online round of hysterics titled Flood Drama in Germany: We’re to Blame! by Jakob Augstein. According to Augstein, today’s German flooding is a result of man’s sins against the climate. Climate deniers are mostly to blame for the “Katastrophe“.Pierre Goselin, No Tricks Zone, 11 June 2013

“Data please.”  
Data that sea ice is a factor in polar bear carrying capacity? Do you really doubt something so obviously true?

Or is it the decline in sea ice that we doubt here? It’s so hard to keep track.

——————–
My request was for Eustace to provide data for his claim that others are not providing data to support their claims which, oddly, he forgot to do.
Since you brought up an curious Straw man argument that I might doubt that, ” sea ice is a factor in polar bear carrying capacity? Do you really doubt something so obviously true?”, I’ll point out that there doesn’t appear to be a published optimum Sea ice amount for the optimum success rate for Polar Bears in harsh climates, such as the Arctic.
Could there be too much Ice, as perhaps there is in such places as Antarctica?
Polar Bears seems to have the highest life expectancy in warm zoos with little or no ice.

Should history repeat itself with a new mini ice age the media and public are also sure to repeat the cycle as well ? discus.
what is the casue ? well there is all the pollution ! now thats a theme thats running even now .
And who is to blame for that pollution? well we all know how the media loves pitch black steam pollution from cooling towers and this is in the good times !
So the answer is quite simple, industry will be blamed, the bigger, the more so, and with even better photoshops. Even if they have cleaned up their act the dwell time/delay curve will be used by the media as a sharp stick to poke them with as a way of expressing the populations pent up frustration, because “someone has to be blamed”, it does not make a good story if its just a natural change in the weather.
The best form of defence is then surely attack, and with the science we now have through WUWT and all the other brilliant contributors to the game its time to turn the blame to the wamists for wasting so much time and effort that could otherwise have been spent preparing for the new minimum.

@Lyan;
Currently sea ice is at the baseline average, higher than the last several years. Maybe it’ll crash again this summer, forcing the Dear Polies to survive on berries and goslings, again.

Actually, these are mythical polar bears, the real ones having gone extinct during one of the many previous warmer-than-now periods, especially during the Eemian interglacial, some 110-130k years ago.

We know that polar bears survived an ice free Arctic. Here are some reasons why they have proved to be so resilient over the past 10,000 years.
Alternative Foods

Abstract
Estimating the Energetic Contribution of Polar Bear (Ursus maritimus) Summer Diets to the Total Energy Budget
The analysis indicated that it is possible for polar bears to maintain their body mass while on shore by feeding on arctic charr and seal blubber. Polar bears of body masses up to 280 kg could gain sufficient energy from blueberries to match the daily energy loss.

Abstract
Food habits of polar bears on land during the ice-free period in western Hudson Bay were examined between 1986 and 1992. In contrast to previous studies, feeding on vegetation during the ice-free period was common……

Abstract
Analyses were made of 233 scats collected from islands in James Bay and 212 scats gathered on the southwest coast of Hudson Bay. Birds, primarily Anatidae, were the most commonly used summer and autumn food of bears in James Bay. Marine algae and grasses were the foods most often eaten by bears on the mainland….

Abstract
Bears which fed in the dump were significantly heavier than those which did not. There was no evidence that bears using the dump gained either reproductive or survival advantages….

Abstract
…During spring and summer, polar bears in some areas increased predation on migratory harp seals and beluga whales. In Western Hudson Bay, bearded seal consumption declined between 1995 and 2001 for both male and female bears and continued to decline among females up to the most recent sampling (2004)….Overall, our data indicate that polar bears are capable of opportunistically altering their foraging to take advantage of locally abundant prey…

Swimming Abilities

Abstract
Consequences of long-distance swimming and travel over deep-water pack ice for a female polar bear during a year of extreme sea ice retreat
….Between an initial capture in late August and a recapture in late October 2008, a radio-collared adult female polar bear in the Beaufort Sea made a continuous swim of 687 km over 9 days and then intermittently swam and walked on the sea ice surface an additional 1,800 km…..The extraordinary long distance swimming ability of polar bears, which we confirm here, may help them cope with reduced Arctic sea ice……

Abstract
Polar bear cubs may reduce chilling from icy water by sitting on mother’s back
…We describe an observation of a polar bear cub on its mother’s back while the mother was swimming among ice floes in Svalbard, Norwegian Arctic. Similar observations are to our knowledge not earlier described in the scientific literature. We point out that this behaviour minimize exposure to cold water and hence significantly may reduce chilling of the cub….

If sea ice was contracting, it would mean that the polar bears have to go less distance to get a decent feed of seal steak. Also the density of seal steaks on the edge of the sea ice would increase.
Feast time !! No more 200km trek to get a steak, Hog’s Breath is just round the corner.

Ryan, are you referring to “K” as “The Equilibrium Constant,” or as a “Strike Out?”
We need some polar bears down in New England, as the seals are becoming a royal pain. The only thing that eats seals now is Great White Sharks, which are becoming more common and also eat tourists. Therefore, if the bears ate a few tourists, it would be OK, because bears are much cuter. It’s a price we’ll have to pay to increase the stocks of codfish. (100,000 seals eating five codfish a day is 182.5 million codfish per year.) Seals aren’t so cute, when seafood is no longer affordable, and polar bears become cuter.

“Maybe not despite, but rather because of declining Sea Ice?”
I believe this to be true. Hunting seals on ice is a two dimensional problem. Hunting with no ice and you have linear shorelines as your hunting grounds – the seals need the ice, too, otherwise they would have to conduct their fishing and birthing activities on land.
I’m not sure what CAGW proponents think the polar bear did during much hotter times in the Holocene and in warmer interglacials. They didn’t magically appear during the little ice age, for example, but rather are 600,000yrs old – and were brown bears before that. Hate to break this news to the bulk of alarmists and even to “experts”.

Thanks JabbaTheCat. If anyone bothers to read the paper you find that polar bears appear to be ‘managed’. ‘Harvesting’ is allowed if populations are thought to require it for a variety of reasons.
God save the polar bears from conservationists.

Billy Liar
June 11, 2013 4:08 pm

Oh, I forgot, the conservationists also pull a tooth from every polar bear they capture. So if you hear a polar bear with a lisp it’s been ‘researched’by a conservationist.

To clarify my prior comment: Polar bears are cuter than Great White Sharks, (and also many tourists, but tourists have wallets.)

Well it’s a good thing polar bears reach maturity and reproduce in one quarter of a season…

More likely no HUNTING allowed. Humans are the main predators of Polar bears. Also bears are feeding at human dumps and even invading cabins/houses.

The quote from Dr Murry sadly still needs reflecting upon….”It doesn’t matter how beautiful your theory is, it doesn’t matter how smart you are. If it doesn’t agree with the data, it’s wrong!” Feynman
There are some who still don’t get it. Their imagination is greater and more supreme than truth.

I know someone posted this before.. but what the heck.
A daddy polar bear and a baby polar bear were walking across the ice and the baby polar bear said to the daddy polar bear, ”Dad, am I a polar bear?,
”Yes” said the daddy polar bear, “you are”.
After a while the baby polar bear asked again, “Dad am I really a polar bear?”
and the daddy polar bear said, “Yes, you really are a polar bear, why do you ask?”
and the baby polar bear said………..
