"Only few times I have seen beautifully fat mothers with beautifully fat young. Many times I have seen horribly thin bears, and those were exclusively females — like this one here," Langenberger writes in the caption of her photo.
In the Arctic, polar bears face a grim scenario due to climate change. Rising temperatures have caused sea ice to melt. This sea ice is where polar bears hunt seals. Without it, the bears have turned to other, less abundant food sources on land such as snow geese and caribou.


Polar bears are a keystone species. This is where the world is headed. Its also what parts of the world are suffering with now.
 
if'n I ever run into that poor SON OF A BEAR he gets a few 45.70 hardcasts to the head out of a Marlin lever Guide Gun from me Luddley !! Most likely photo shop or similar though .
 
OMG obviously a vast rightwing conspiracy to sink polar bears. Having fun are we Luddly, trying to play make believe with your lefty friends, lol! Hey, did you EVER find those debates I was asking about, lolol Typical degrowther, phoney baloney, good time rock-n-roller.
 
" Biologist Mitchell Taylor has studied polar bears and advised governments for more than thirty years, living in the high Arctic for much of that time.

“They’ve certainly been around through the last interglacial period,” says Taylor. “During that interglacial it was warmer than it is now: we had pine trees on Baffin Island, deciduous forests north of the Arctic Circle. Polar bears had to have survived that or we wouldn’t be seeing polar bears now,” he says."

Polar bears: Threatened species or political pawn?
 
Left wing enviro whackos just can't let the truth be known about polar bears. They raise too much money having the beautiful beasts as their poster children for climate change.
 
Only a true C-Fag dodo would link to a site called 'The Dodo'.........:laugh:. (That polar bear has cancer......).

B. Kidd

Do you know WHY it refers to the Dodo? Do you know what the Dodo was?

No, of course you don't.

Grow up and stop thinking that saving and passing our planet on to our children makes one a "C-Fag". Its what responsible adults do.

Brains and discernment work better than compassion David !! The 'op' looks like 'bs' to me .
 
"Survived" doesn't mean "didn't suffer"

If you look into this -- you'll find that at the bottom of the polar bear's woes is really the question of whether Eskimos should retain access to hunt them and raise cash by selling the permits to non-native hunters for large exorbitant guide fees.. If they were TRULY in crisis -- this practice would be severely limited or curtailed outright.
So like so many enviro causes -- instead of hitting this issue head on --- they go 'bout it sideaways by making the Global Warming excuse and photoshopping pictures.

Natives want the best dressing put on the Polar Bear problem -- enviros want it to painted bleak. For the Eskimos it's a major source of income.. Fact is --- the NATIVES know better than the scientists what the situation is.. And if their livelihood was threatened -- they'd be backing off the hunt..

Sad story -- but true.. Money and politics...
 
Bah, this is to easy. You have to do better than that shill! Global warming fraud: Iconic polar bear on melting ice cap a hoax


Nope. The photo in the OP is real and true.

You're thinking of this one and even that one is not a "hoax".

Follow the links in the OP for more about that photographer.

Melting-ice-polar-bear_thumb.jpg

Already did that Luddly. Years ago. The photog was hired by a big building full of lawyers pretending to be defenders of nature. Lots of them ya know. Like NRDC, WWF, etc. I don't recall which one. The photo was commissioned for a calendar in preparation for a large GWarming conference so that their booth would attract more attention..

Light and shadows not right at all. Bear is lit from the right.. but shadow of the "berg" goes off into the foreground and that source would be very low in the sky.. Even if it WAS real. That bear is no where danger. Plenty of pics of bears on bergs..
 
From the Wikipedia article on Polar Bears

Climate change
The International Union for Conservation of Nature, Arctic Climate Impact Assessment, United States Geological Survey and many leading polar bear biologists have expressed grave concerns about the impact of climate change, including the belief that the current warming trend imperils the survival of the polar bear.[30][149][150][151][152][153]

The key danger posed by climate change is malnutrition or starvation due to habitat loss. Polar bears hunt seals from a platform of sea ice. Rising temperatures cause the sea ice to melt earlier in the year, driving the bears to shore before they have built sufficient fat reserves to survive the period of scarce food in the late summer and early fall.[111] Reduction in sea-ice cover also forces bears to swim longer distances, which further depletes their energy stores and occasionally leads to drowning.[154] Thinner sea ice tends to deform more easily, which appears to make it more difficult for polar bears to access seals.[68] Insufficient nourishment leads to lower reproductive rates in adult females and lower survival rates in cubs and juvenile bears, in addition to poorer body condition in bears of all ages.[30]


Mothers and cubs have high nutritional requirements, which are not met if the seal-hunting season is too short.
In addition to creating nutritional stress, a warming climate is expected to affect various other aspects of polar bear life: Changes in sea ice affect the ability of pregnant females to build suitable maternity dens.[27] As the distance increases between the pack ice and the coast, females must swim longer distances to reach favored denning areas on land.[30] Thawing of permafrost would affect the bears who traditionally den underground, and warm winters could result in den roofs collapsing or having reduced insulative value.[30] For the polar bears that currently den on multi-year ice, increased ice mobility may result in longer distances for mothers and young cubs to walk when they return to seal-hunting areas in the spring.[30] Disease-causing bacteria and parasites would flourish more readily in a warmer climate.[68]

Problematic interactions between polar bears and humans, such as foraging by bears in garbage dumps, have historically been more prevalent in years when ice-floe breakup occurred early and local polar bears were relatively thin.[149] Increased human-bear interactions, including fatal attacks on humans, are likely to increase as the sea ice shrinks and hungry bears try to find food on land.[149][155]


Swimming
The effects of climate change are most profound in the southern part of the polar bear's range, and this is indeed where significant degradation of local populations has been observed.[153] The Western Hudson Bay subpopulation, in a southern part of the range, also happens to be one of the best-studied polar bear subpopulations. This subpopulation feeds heavily on ringed seals in late spring, when newly weaned and easily hunted seal pups are abundant.[141] The late spring hunting season ends for polar bears when the ice begins to melt and break up, and they fast or eat little during the summer until the sea freezes again.[141]

Due to warming air temperatures, ice-floe breakup in western Hudson Bay is currently occurring three weeks earlier than it did 30 years ago, reducing the duration of the polar bear feeding season.[141] The body condition of polar bears has declined during this period; the average weight of lone (and likely pregnant) female polar bears was approximately 290 kg (640 lb) in 1980 and 230 kg (510 lb) in 2004.[141] Between 1987 and 2004, the Western Hudson Bay population declined by 22%.[156]

In Alaska, the effects of sea ice shrinkage have contributed to higher mortality rates in polar bear cubs, and have led to changes in the denning locations of pregnant females.[110][157] In recent years, polar bears in the Arctic have undertaken longer than usual swims to find prey, resulting in four recorded drownings in the unusually large ice pack regression of 2005.[154]

Jump up^ Mitchell Taylor, a former polar bear researcher for the Nunavut government, thinks that Arctic warming has been caused by natural phenomena and is not a long-term threat to the polar bear. After his retirement, he was not re-appointed to the international Polar Bear Specialist Group (PBSG), giving rise to speculation that he was excluded from the group because of his views on climate change. According to the PBSG chair, appointments to the PBSG are given to scientists who are currently active in polar bear research, and that as a retired researcher, Taylor did not qualify.

Oh Gawd............leave it to the OP to come up with the most absurd shit we see on the board. The polar bears have never been doing better. The whole polar bear ruse was yet another bogus fAiLed prediction postulated by the AGW k00ks about 20 years ago.

Of course, any suffering done by any animal is the fault of a Republican or George Bush!!! Who cant see that?:2up: If progressives were the only people that existed on earth, it'd be far more awesome for animals who would do no suffering.:rock:
 
Typical right wing compassion, they can make anything look like a "hoax."



s0n....the difference between conservative and progressives is that progressives get hysterical about EVERYTHING!!! Progressives also think that you can fix any and all problems if you just fix the institutions.............make ALL problems go away, which of course, the conservative knows is absurd.
