Polar bears fight for survival as sea ice melts Subscribe to the Guardian HERE: http://bitly.com/UvkFpD As winter approaches, polar bears in sub-arctic Canada begin to migrate off the tundra and head out onto the ice for the winter, where they can hunt for seals. However, climate change is delaying freeze-up, keeping the bears out on the tundra for longer away from their main food source.

Polar bears in danger: Global warming will wipe one third of polar bears out by 2050 - TomoNews
 
01:09
GLAND, SWITZERLAND — Polar bear numbers could drop by a third over the next 35 years because of global warming. The warning comes in a study by the International Union for the Conservation of Nature (IUCN), phys.org reported. The global polar bear population is estimated to stand at 26,000. The study suggests there is a 70 percent chance that figure will drop 30 percent by 2050. Melting sea ice caused by global warming is the main threat to the survival of polar bears. Polar bears depend on sea ice as a floating platform to hunt seals, which can outswim them in the water. The presence of manmade chemicals in the food chain is another major threat to polar bear numbers. The IUCN monitors endangered species on its Red List. The organisation classifies polar bears as “vulnerable,” meaning the species faces a high risk of extinction in the wild. ----------------------------------------­--------------------- Welcome to TomoNews, where we animate the most entertaining news on the internets.

Wild Polar Bear - Predator of Arctic Ocean | Ice Bears (2018 Documentary)
 
48:19
The polar bear is a carnivorous bear whose native range lies largely within the Arctic Circle encompassing the Arctic Ocean its surrounding seas and surrounding land masses. Polar Bear The Polar Bear is the largest carnivorous mammal on land and must hunt regularly to ensure that it is well-fed and maintains its insulating layer of fat to keep it warm. The skins and blubber of Ringed Seals make up the bulk of the Polar Bears' diet as they often leave the remaining meat which provides an important sources of food for other animals such as Arctic Foxes. Although Seals are their primary source of food Polar Bears also eat birds berries fish and Reindeer (particularly during the trickier summer months) along with the occasional Walrus. The carcasses from large marine mammals including Seals Walruses and even Whales also provide a regular food source for Polar Bears that are said to have such a good sense of smell that they are able to sniff them out from a considerable distance away. Polar Bears are also known to break into underground Seal dens to hunt the pups inside them

Wide bear looks at boat from shore LEAD IN : Polar bears have become an important emblem of climate change. The huge mammals are threatened with extinction in many areas of the Arctic because of the melting of their sea ice habitat. The WWF says that in order to save the charismatic species, immediate action must be taken to halt global warming. STORYLINE: The United Nations Environment Programme says the world's ice and snow is shrinking - and it's mainly due to global warming. 15 percent of the earth is covered by ice and snow, glaciers, permafrost and frozen lakes. Now the summer ice cap is about 20 percent smaller today than in 1978 (UN climate panel reported February 2007). Summer sea ice in the Arctic shrank to a record low last year to nearly 40 percent less than the long-term average between 1979 and 2000. If this trend is not reversed, the affects on Arctic wildlife may be catastrophic, according to Dr Neil Hamilton, Director of WWF's Arctic Programme. The birdlife on the archipelago is rich and impressive, with three million pairs of seabirds breeding in the region.

The polar bear (Ursus maritimus) is a carnivorous bear whose native range lies largely within the Arctic Circle, encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. It is a large bear, approximately the same size as the omnivorous Kodiak bear (Ursus arctos middendorffi).[3] A boar (adult male) weighs around 350–700 kg (772–1,543 lb),[4] while a sow (adult female) is about half that size. Although it is the sister species of the brown bear,[5] it has evolved to occupy a narrower ecological niche, with many body characteristics adapted for cold temperatures, for moving across snow, ice, and open water, and for hunting seals, which make up most of its diet.[6] Although most polar bears are born on land, they spend most of their time on the sea ice. Their scientific name means "maritime bear", and derives from this fact. Polar bears hunt their preferred food of seals from the edge of sea ice, often living off fat reserves when no sea ice is present. Because of their dependence on the sea ice, polar bears are classified as marine mammals.[7] Because of expected habitat loss caused by climate change, the polar bear is classified as a vulnerable species, and at least three of the nineteen polar bear subpopulations are currently in decline.[8] For decades, large-scale hunting raised international concern for the future of the species, but populations rebounded after controls and quotas began to take effect.[9] For thousands of years, the polar bear has been a key figure in the material, spiritual, and cultural life of circumpolar peoples, and polar bears remain important in their cultures.

Scientists say the world has only 20,000 polar bears. A movie called "To the Arctic" is part of an effort to save the animals and their home. MERYL STREEP: "Feasting on rich seal meat has made these the largest bears in the world. But now the Arctic is warming, and the sea ice is melting away." The film follows a polar bear mother and her two cubs. MERYL STREEP: "This is a cold stark world, but to polar bear mothers and cubs, it's paradise." Nature photographer Florian Schulz made a book about the Arctic. FLORIAN SCHULZ: "The polar bears won't be able to survive without the ice, and, right now, scientists are predicting that by 2040 or 2050, somewhere in between then, the sea ice in the summer will completely go away." The movie producers had difficulty working in below zero temperatures, and with animals afraid of humans. "Next year we're coming back with stronger cases." The movie and book are part of a larger project to protect polar bears and the Arctic, says Suzanne Apple of the World Wildlife Fund. SUZANNE APPLE: "This area that, that we are focused on called the last ice area in northern Canada, Greenland and Denmark is our research shows that this is the ice that will persist the longest, so we are hoping to protect and preserve that."

When ice melts, polar bears use 5x more energy to swim instead of walk
 
01:41
Climate change and shrinking sea ice is impacting polar bear populations and their ability to forage for food and to produce healthy cubs. BYU biology professor Blaine Griffen analyzed polar bear data from the U.S. Geological Survey and calculated the metabolic rate of polar bears for different activities. He found that it takes five times as much energy for a polar bear to swim than it does for a bear to walk. Since bears are being forced to swim to forage for food since they can't walk across sea ice, this is having a negative impact on the health of the bears and species survival. Special thanks to The U.S. Geological Survey, John Patrick Whiteman, George Durner, and Paul Laustsen for providing images and assistance. Additional video provided by Shutterstock. News Release from Brigham Young University (Author: Todd Hollingshead) One result of melting Arctic ice is that polar bears are forced to swim more often and further than ever to forage for food. New research by BYU biologist Blaine Griffen finds the increase in swimming could permanently affect polar bear populations, leading to smaller bears, reduced reproduction rates and even increased risk of death for the bears. “Bears can more than double their body weight during the springtime foraging season when they hunt seals on the ice,” Griffen said. “As the sea ice melts earlier and earlier, polar bears are forced to swim more and more, both in frequency and distance, to reach seal populations. The time they have to forage is getting cut short and this has huge energetic costs.” According to Griffen’s research, recently published in Polar Biology, it costs polar bears five times as much energy to swim as it does to walk the same distance. That cost became enormous in one case Griffen studied, where a female bear swam 687 kilometers over nine days: the bear lost 22 percent of its body weight and, worse, lost the nursing cub that had started the journey with her. “Their entire world is driven by energy,” Griffen said. “Anything that places that extra energetic strain on the bear will affect its ability to survive.” To determine how much energy polar bears use to swim, Griffen used previously recorded data on the core body temperature and the surrounding water temperature of a bear to estimate the total heat it would have to produce as it swims. Using additional data of a polar bear walking, Griffen was then able to use the relationship between heat production and metabolic rate to determine the metabolic rate of the swimming bear. “I basically confirmed what everyone thought: they’re good swimmers but they’re not very efficient swimmers,” he said. That increased energy output is already showing worrisome effects for two of the 19 polar bear populations observed in the Arctic: western Hudson Bay and southern Beaufort Sea. There, the body size of individual bears is getting smaller — they’re not growing as much because they have less energy — and the number of cubs being produced in litters is beginning to decrease. The end result is decreasing survival rates and smaller polar bear populations. The research is a stark reminder of how climate change can affect the life cycle of specific animal species. This is Griffen’s first publication on polar bears, but it has opened up a new collaboration with Salt Lake City’s Hogle Zoo, where Griffen hopes to work with Hope and Nora, the two new polar bears that arrived this year.

Polar Bears & Their World Of Ice
 
08:11
This is a short video documentary on the magnificent animal the polar bear, and its icy home the North Pole, which is tragically under threat from accelerated human disturbances. I wish to point out that the footage of penguins in this video is false, as they do not inhabit the arctic shelf, only the Southern Hemisphere. The creator of this video may have added them for a more dramatic effect to the video, but either way their presence in the video is wrong as they only inhabit the Southern Hemisphere. Polar bears are actually considered marine mammals by marine scientists, since they have characteristics and features that were adapted for them to have a marine lifestyle. Such as their ability to swim, and a layer of blubber which insulates them from the extreme sub freezing temperatures of the Arctic seas. It is estimated there is around 21000- 28000 polar bears left in the wild, polar bears are a threatened species and are being considered for a place on the endangered species list. Polar bears are almost entirely dependent on sea ice for their ability to survive, a decrease of sea ice in the arctic regions threaten the survival of the polar bear and will continue to, which puts them at risk at becoming endangered as a result of this. Drastic changes to their icy home will change the polar bears behavioral patterns and decrease their numbers, a fact we have already witnessed with polar bear mothers giving birth to their cubs inside of snow dens on the land. The polar bear is an incredible and very powerful animal which inhabits arctic coastlines, and its fate is very much dependent on the nations who control the land on which they live, such as Canada, The United States, Norway and Greenland. It fills my heart with great sadness that this animal could be gone from us one day, which is why it is very important we keep pressure on these nations to help protect and conserve the polar bear and it's incredible world of ice for which it has been absolutely and perfectly designed for and which is essential for it's needs. If you don't appreciate the natural world or consider it irrelevant, then you just simply haven't been there to experience just how awesome and unbelievable this thing is, and why it's so important we all band together to protect and conserve it for ourselves and the benefit of our future generations, and for the animals as well who are essential to the sustainably of life on this planet. Our world is absolutely amazing and we can't lose these miracles of nature and their equally amazing natural environments. Do whatever you can, and help play a part in the conservation of these incredible arctic animals. Thank You

But sea ice is decreasing by 14% each decade due to global warming. This means bears must travel further and further to find seals. Researchers placed point-of-view cameras on the bears to track them in their dire search for food. As the sea ice continues to fragment the bears' ratio of energy expenditure to consumption will grow.

As climate change melts the Arctic, polar bears have nowhere to turn
 
02:20
Climate change continues to make its presence felt on our planet. One area that's warmed-up more than other parts of the globe is the Arctic. That warming has caused ice in the region to thin, leaving polar bears nowhere to turn. CGTN's Hendrik Sybrandy reports. Merav Ben-David, a professor at the University of Wyoming, has been studying polar bears for years now. From Russia to Alaska, their arctic habitats are melting under their feet. They hunt on sea ice. Ocean currents and the wind push that ice to the west, away from landmasses like Alaska. “They always had to walk against the drift to remain in Alaska,” she said. That thinning ice doesn’t weigh as much. According to Ben-David, that means that the polar bears have to walk more, or faster, because the ice drifts faster. It’s like walking down an up escalator. It’s not a normal action. You expend a lot more effort than if you were going in the opposite direction and you don’t get very far. It’s a real challenge for female polar bears with cubs.

In late July, 2015, they were traveling through Hinlopen Strait, west of the largest island, Spitsbergen—an impossible route some summers, when pack ice blocks passage. But that summer, ice was especially sparse, making hunting harder for polar bears. These apex predators favor waiting at the sea ice’s edge, striking seals as they approach. A few days earlier, the Wilkinson family had been farther north, near the ice. There, bears looked healthy. But the scene just after midnight on July 23 was desperate. Mother and cub were struggling, skin hanging loose. According to Jon Aars, of the Norwegian Polar Institute, the cub, seven or eight months old, was likely to die if its mother didn’t eat soon. She probably wasn’t lactating. Wilkinson saw the bear sniff the air, picking up something of interest. This thin female couldn’t attack a healthy, full-grown walrus. A carcass would solve their problem. If the walrus were weak or sick, predation might be an option. But that walrus was alive and well. The situation was unworkable. The search for food went on.

Polar Bears Play and Wrestle as they wait for Sea Ice: Nature Relaxation Therapy
 
01:03:36
Polar Bears like to play and wrestle as they wait for the sea ice to form near Churchill, Canada. It looks like a violent fight and a human would certainly not stand a chance, but for the bears it's a way to kill time and boredom and maybe test their skills for when it's time to compete for a mate. They have no legitimate food source on land other than the occasional stranded seal or dead caribou so they are bored and the males will spar or practice fight. It's a truly amazing site to behold and with the tours, you can often get very close to them safely and without disturbing them. They look so fluffy and cuddly but they would happily eat you if you were down on their level. Please enjoy this truly spectacular behavior and I hope it brings you calm, relaxation, and healing meditative peace. I've tried to pick music that will help in your relaxation and meditative practices and provide a peaceful background to help you find balance and stress relief in the new year. I'm a nature cinematographer and I've collected a large library of footage over the years. I've decided to share them with you. Most of these clips can be licensed as stock footage through Pond5 or directly through me. https://www.pond5.com/artist/hhuntington2#1/2063 If you are curious why there is little ambient sound, it is because I often did not capture it which is standard in the industry. On some, I used files that had the sound removed for stock footage purposes. #relaxation #naturevideo #animals The basics from Wikipedia: The polar bear (Ursus maritimus) is a hypercarnivorous bear whose native range lies largely within the Arctic Circle, encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. It is a large bear, approximately the same size as the omnivorous Kodiak bear (Ursus arctos middendorffi). A boar (adult male) weighs around 350–700 kg (772–1,543 lb), while a sow (adult female) is about half that size. Although it is the sister species of the brown bear, it has evolved to occupy a narrower ecological niche, with many body characteristics adapted for cold temperatures, for moving across snow, ice and open water, and for hunting seals, which make up most of its diet. Although most polar bears are born on land, they spend most of their time on the sea ice. Their scientific name means "maritime bear" and derives from this fact. Polar bears hunt their preferred food of seals from the edge of sea ice, often living off fat reserves when no sea ice is present. Because of their dependence on the sea ice, polar bears are classified as marine mammals. Because of expected habitat loss caused by climate change, the polar bear is classified as a vulnerable species. For decades, large-scale hunting raised international concern for the future of the species, but populations rebounded after controls and quotas began to take effect. For thousands of years, the polar bear has been a key figure in the material, spiritual, and cultural life of circumpolar peoples, and polar bears remain important in their cultures. Historically, the polar bear has also been known as the white bear. The polar bear is a marine mammal because it spends many months of the year at sea. However, it is the only living marine mammal with powerful, large limbs and feet that allow them to cover miles on foot and run on land. Its preferred habitat is the annual sea ice covering the waters over the continental shelf and the Arctic inter-island archipelagos. These areas, known as the "Arctic ring of life", have high biological productivity in comparison to the deep waters of the high Arctic. The polar bear tends to frequent areas where sea ice meets water, such as polynyas and leads (temporary stretches of open water in Arctic ice), to hunt the seals that make up most of its diet. Freshwater is limited in these environments because it is either locked up in snow or saline. Polar bears are able to produce water through the metabolism of fats found in seal blubber.Polar bears are therefore found primarily along the perimeter of the polar ice pack, rather than in the Polar Basin close to the North Pole where the density of seals is low. Annual ice contains areas of water that appear and disappear throughout the year as the weather changes. Seals migrate in response to these changes, and polar bears must follow their prey. In Hudson Bay, James Bay, and some other areas, the ice melts completely each summer (an event often referred to as "ice-floe breakup"), forcing polar bears to go onto land and wait through the months until the next freeze-up. In the Chukchi and Beaufort seas, polar bears retreat each summer to the ice further north that remains frozen year-round.

Starved polar bear in victim of warming Global due to record sea ice melt looked like a Rug
 
02:14
The polar bear's emaciated body looked more like "a rug" than one of the world's most powerful predators. For all its hunting prowess, the giant animal appears to have starved to death as it made a desperate journey north on the Arctic island of Svalbard in search of seals. Experts fear polar bears will increasingly suffer a similar fate as global warming melts the sea ice that allows them to hunt for their main source of food. Ian Stirling, who has studied polar bears for nearly 40 years, told The Guardian newspaper that he found the animal on Svalbard in July. "From his lying position in death the bear appears to simply have starved and died where he dropped," Stirling said. "He had no external suggestion of any remaining fat, having been reduced to little more than skin and bone." The bear was examined by Norwegian scientists in April about 150 miles south and seemed to be healthy at that time. "Most of the fjords and inter-island channels in Svalbard did not freeze normally last winter and so many potential areas known to that bear for hunting seals in spring do not appear to have been as productive as in a normal winter," said Stirling, of conservation group Polar Bears International. "As a result the bear likely went looking for food in another area but appears to have been unsuccessful." The bear is thought to have been heading north in a desperate search for sea ice that would allow it to hunt for seals. Scientists believe the Arctic could be essentially free of sea ice in September by 2054. A study published in July found that the Arctic could be essentially free of sea ice in September as early as 2054. Polar Bears International says on its website that the bears evolved for a life on sea ice, "which they rely on for reaching their seal prey." The loss of sea ice has meant an increase in drownings and cannibalism, and a general decline in population. Ashley Cooper, the photographer who took the picture, said the sight of the dead polar bear was "desperately sad." "There was just no fat on it. It was just completely shrunken and shriveled, a very, very skinny specimen of a polar bear," he said in a telephone interview. "It looked basically like a rug because there was just no weight on it at all." Cooper said scavengers had not eaten parts of the body and there were no signs of decomposition, which happens slowly in the low temperatures of the Arctic. He said he saw five live polar bears during a 12-day trip to Svalbard in July. Three looked "quite thin and not in great condition" and the only one that looked healthy was hunting on sea ice barely strong enough to support its weight about 550 miles from the North Pole. Cooper said the fate of the bear was "what [all] polar bears have got to look forward to over the next 10 to 20 years." "There isn't a future for them unless we can very rapidly get on top of climate change," he said. Jeff Flocken, at the International Fund for Animal Welfare, told The Guardian it was difficult to blame climate change for a single death. But he added "it couldn't be clearer that drastic and long-term changes in their Arctic habitat threaten the survival of the polar bear." "The threat of habitat loss from climate change, exacerbated by unsustainable killing for commercial trade in Canada, could lead to the demise of one of the world's most iconic animals, and this would be a true tragedy."
