Animals of the Antarctica, particularly penguins, could become easy prey for polar bears. It wouldn’t take long for the polar bears to wipe out all of the penguins and the seals. Left with no food, the polar bears would not survive either.

In total, only about 4 million people live in the Arctic worldwide, and in most countries indigenous people make up a minority of the Arctic population. The Inuit in Canada and Greenland, and the Yu’pik, Iñupiat, and Athabascan in Alaska, are just a few of the groups that are native to the Arctic.

Polar bears live in the Arctic, but not Antarctica. Down south in Antarctica you’ll find penguins, seals, whales and all kinds of seabirds, but never polar bears. Even though the north and south polar regions both have lots of snow and ice, polar bears stick to the north.

These species, which are frequently found in shallow water, would struggle crossing the deep ocean surrounding the southernmost continent. Thus, no sharks in Antarctica… yet. Closer to home, the Atlantic White Shark Conservancy has been witnessing what happens when sharks get too cold.

If polar bears were to go extinct, the population of walruses, seals, whales, reindeer, rodents and birds would increase and get out of control. Since seals create breathing holes, in about 100 to 200 years this will break up the ice and split the arctic circle.

Food Preferences & Resources When other food is unavailable, polar bears will eat just about any animal they can get, including reindeer, small rodents, seabirds, waterfowl, fish, eggs, vegetation (including kelp), berries, and human garbage.

Sadly for polar bears, loss of sea ice today means starvation. By Jeremy Torr. Washington, 12 March 2019. Most researchers suggest that the correlation is because polar bears need sea ice to help them hunt seals, their main food source.

Polar bears are listed as vulnerable to extinction by the International Union for Conservation of Nature (IUCN), with climate change a key factor in their decline. Studies show that declining sea ice is likely to decrease polar bear numbers, perhaps substantially.

According to Liodden, between 1963 and 2016, an average of 991 bears were hunted worldwide every year, totaling about 53,500 bears. He calls that number “crazy high,” given how many polar bears are believed to be left and how slow they are to reproduce.

With Arctic sea ice in a spiraling decline—2020 was recently declared the second-lowest ice year in the satellite record—it’s an axiom of climate change that polar bears are in peril. …

With an estimated 22,000 to 31,000 polar bears left around the world, the survival of these majestic creatures is critical. “Polar bears are not going to be extinct in the next few years, as many people say,” said Laforest. “The current estimate is by 2050, there’ll be a one-third decline in the population.”

Key Findings. Results of three new polar bear population surveys were published in 2020 and all were found to be either stable or increasing. Southern Beaufort polar bear numbers were found to have been stable since 2010, not reduced as assumed and the official estimate remains about 907.

By the end of November 2020, much of the meltwater on the ice had refrozen. Last year, unusually warm air and water led to record-breaking melting across the Larsen C Ice Shelf. It is the largest remaining ice shelf along the Antarctic Peninsula, even though it lost a Delaware-sized iceberg in 2017.

If all the ice covering Antarctica , Greenland, and in mountain glaciers around the world were to melt, sea level would rise about 70 meters (230 feet). The ocean would cover all the coastal cities. And land area would shrink significantly. Ice actually flows down valleys like rivers of water .

Climate change Some of Antarctica has been warming up; particularly strong warming has been noted on the Antarctic Peninsula. A study by Eric Steig published in 2009 noted for the first time that the continent-wide average surface temperature trend of Antarctica was slightly positive from 1957 to 2006.

Sediment analysis from a layer deep within the Earth revealed that the dirt had first formed on land, not the ocean. A new paper reveals that the frozen continent of Antarctica was once a temperate rainforest.

For most of the past 100 million years, the south pole was a tropical paradise, it transpires. “It was a green beautiful place,” said Prof Jane Francis, of Leeds University’s School of Earth and Environment. “Lots of furry mammals including possums and beavers lived there. The weather was tropical.

The maximum body temperature a human can survive is 108.14°F. At higher temperatures the body turns into scrambled eggs: proteins are denatured and the brain gets damaged irreparably. Cold water draws out body heat. In a 39.2°F cold lake a human can survive a maximum of 30 minutes.
