Although Australia is in the Southern Hemisphere, it is still covered by a news story-the Arctic Circle is warmer than 32 degrees, the Arctic glaciers are melting at their fastest rate in 1500 years, and global warming is in a vicious circle. Polar bears are extinct this year.
This is a set of real pictures taken in the Arctic Circle as a polar bear struggles to swim forward in a thin ice floe.
It tried to lie on one of them, but the floes were too small to bear its weight.
It has been swimming for many days, 232 hours (9 days), 687 kilometers away, it has finally found a piece of ice that can bear its weight, fortunately, it can lie down on the ice for a breath.
In today's Arctic, tundra in high latitudes turns green ahead of time, precocious eggs, and migratory birds miss their foraging time. Polar animals face drowning.
Arctic summer sea ice has fallen by nearly half over the past 40 years, according to NASA. Only about 3.5 million square kilometers remain.
Jennifer, an Arctic meteorologist, predicts that one summer before 2040, the ice in the Arctic Ocean could disappear altogether, 60 years earlier than the countdown predicted more than a decade ago.
"the consequences of an ice-free Arctic may be unbearable for mankind."
The melting of polar ice affects not only animals, it also causes global ice to melt, and global warming enters the vicious cycle of acceleration.
Why would you say that?
Because when ice melts, the blue parts of the poles (sea water) are more than the white ones (ice cubes), and dark colors are more endothermic.
In addition, scientists worry that if the Antarctic permafrost also begins to thaw, then carbon dioxide, methane, such as Greenhouse Effect gas that was frozen in the soil, will be released, then global warming will be more difficult to contain.

If green plants grow in the frozen soil, it will absorb more heat than white snow and ice in the past, accelerating global warming.
The melting of polar ice can also have another serious impact: disrupting ocean currents. If the Arctic ice melts abnormally, it slows down the meridional flipping circulation of the Atlantic, and ultimately affects the climate in all regions, Narctic said.
Of course, the polar ice melts, and the world knows: sea-level rise.
It's a nightmare for all coastal countries, and the Maldives will disappear in decades, everyone knows, but what you don't know is that Australia will also be affected.
As a country in the Southern Hemisphere, the accelerated melting of the North Pole aggravates Greenhouse Effect, and the South Pole also speeds up the melting.
By 2100, sea levels could rise by 2 to 2.7m, according to the (NOAA) study by the National Oceanic and Atmospheric Administration.
Australia's major cities are coastal, in other words, parts of Sydney, Melbourne, Brisbane and the Gold Coast will be submerged.
According to the new computer model, according to the Herald Sun, if climate change does not abate, cities such as Albert Park,Docklands and St Kilda in Melbourne will be flooded by rising sea levels.
If sea levels do rise 74 centimeters by the end of the century, popular beaches such as Bells,Brighton and Ocean Grove will be washed away.
These attractions will no longer exist.
Recently, on the Coastal Risk Australia website, people can view the impact of climate change on their regions. Nathan Eaton, the site's co-founder, says it's hard to see what the rising sea level means to their homes, communities, and their favorite places in decades.
"our main goal is to raise awareness of the dangers of sea-level rise, and it will help all Australians prepare for these changes," he said. We expect the site to be applied at all levels of government, policy, heritage conservation and community participation. "

Eaton and his partner Nathan Quadros used Google technology and local tidal data to map the effects of rising sea levels on cities, towns and beaches in three different scenarios (sea level rise of 44 cm, 54 cm, and 74 cm, respectively). Another website, ClimateValuation, will also offer owners a valuation of the impact of climate change on their home insurance and property value.
Besides Melbourne, Keynes, Byron Bay and Gold Coast will be swallowed up by the sea. Brisbane Airport and Sydney Airport are also in threat.

Australian researchers have compared the coverage of Antarctic mainland sea ice from the 1960s to the present. Take the Antarctic glacier Thwaites, for example, which has been warmed by the sea in threat over the past few decades. The glacier has been receding at a rate of about 400 meters a year, and will even fall apart in the next 500 to 1000 years.
By then, the sea level will rise by 2 meters!
The speed of sea-level rise can not be controlled, where will human beings go …
The global average sea level has risen by about 3.4mm a year since 1993, about twice the average growth rate of the 20th century, according to (NOAA), the national ocean and atmospheric administration.
The heat has brought not only the melting of the North and South poles, but also a series of disastrous data: a new study by the Global Daily showed that the suicide rate rose 2.1% for every temperature rise in the United States by one degree. Four people were killed and 11 injured as a result of a tsunami in Greenland due to rising sea levels;
Kiribati, the Pacific island nation, will not be able to stop rising water levels once and for all, and Britain is even considering a "climate refugee visa"; the global underground cable could be destroyed in half by global warming in 2033; Global warming in 2100 is expected to create 2 billion "climate refugees" homeless, which will cause a series of socio-political and economic problems;
However, after this data, human beings do not feel the crisis, still wanton to exert enormous pressure on the natural environment …
If mankind still treats Mother Earth in this way, retribution may soon come!
