Antarctica turned into a blood red, New Zealand mussels were burned to death by seawater-humans may lose the earth!

Hawking once predicted:”If global warming continues to intensify, mankind will not be able to survive on the earth.”

This prediction may become a reality, and we may lose our planet. Earlier this year, a creepy scene appeared on Galinz Island, near the northernmost peninsula of Antarctica:

A blood-red stripe covered the snow in Antarctic ice, like a watermelon juice. Or strawberry juice, like the blood stains left after the extreme fighting, the Antarctic continent was stained with blood.

First, the”Blood” continent

Antarctica has become a”Blood” continent, the originator is a kind of snow algae, Also known as watermelon snow, the color is reddish or pink and smells like fresh watermelon. This kind of algae is warm and hidden in the snow and mountains around the world. It hibernates in the snow and ice in winter. When the temperature increases in summer, the algae will bloom and spread red flower-like spores.

However, The spread of this algae in the Antarctic is more like an early warning, and it is also a microcosm of the global crisis caused by global warming in recent years.

Snow algae are deep red, less reflected sunlight, the heat absorbed increases, and the surrounding ice melts quickly because of the heat. The more ice melts, the faster the algae will spread. In turn, the increase in algae will cause more ice to melt and more algae to bloom, which is a vicious circle.

Second, warming Antarctica

Future Five issued by the World Meteorological Organization The Annual Global Temperature Prediction Assessment shows that The past five years have been the hottest five years on record, and the probability of becoming the hottest year in history is as high as 74.67%in 2020. In January 2020, Antarctica experienced the highest temperature ever recorded at 20.75 degrees Celsius. In the past three decades in Antarctica, the rate of warming has been more than three times the average rate of the rest of the world.

Eagle Island near Antarctica, in just 9 days, more than 20%of the snow melted. Because of the increase in temperature, the thermophilic polar snow algae spread on the Antarctic continent, staining the Antarctic with blood red.

Over the past 5 years, Antarctica’s melting ice cap has exceeded 1.5 trillion cubic meters, krill Become a victim of climate warming and die a lot, which will affect krill-eating animals, such as Adelie penguins, hat belt Penguins and humpback whales. A large number of penguins have died due to food shortages, and have lost their breeding habitats due to the disappearance of sea ice, the retreat of glaciers and the rupture of ice shelves.

Third, the warming Arctic

On June 20, 2020, the The town of Vrhoyansk also showed the highest temperature ever-38 degrees Celsius. In the first half of 2020, the Arctic has experienced several high temperatures above 30 degrees, and this time the high temperature of 38 degrees directly refreshed the limits of the Arctic.

The Arctic is an important ice area on the earth. As long as the temperature is above zero, the ice will melt. But now there is a rare 38-degree high temperature, an additional 38 minutes of high-temperature, will trigger the melting of hundreds of millions of tons of ice in the entire Arctic.

If the Arctic sea ice and the Greenland ice shelf melt further, the Arctic will lose its role as the earth’s “coolant” and the earth’s temperature will rise further. The melting of glaciers will also destroy the walrus habitat and cause some fish to migrate to the colder north.

Four, white coral

In the past 100 years, human activities have induced The rapid global warming has pushed the ocean temperature up by 0.68 degrees Celsius. Although this number looks small, it is enough to harm corals and zooxanthellae.

The color of the coral comes from tiny zooxanthellae. This organism not only makes the coral look beautiful, but also provides nutrients to the coral. Therefore, there is a symbiotic relationship between coral and seaweed.

In 2020, overheated seawater in eastern Australia flooded into the Great Barrier Reef, and the seawater temperature reached the highest point in history, killing zooxanthellae in corals, and corals were forced to coexist with the body. The algae separated, revealing white bones. If the corals cannot recover and eventually die, about 9,000 species of fish, mollusks, whales and other creatures may lose their homes.

Five,”scalded” mussels

In 2014, the sea in the western United States The water temperature rises by 3°C, which poses a deadly threat to the living creatures in the surrounding waters, causing the death of a large number of seals, seabirds and other animals. Today, this similar warming has occurred in New Zealand.

In 2020, New Zealand’s North Island experienced a severe drought, with many regions experiencing no rain for more than 40 consecutive days. The impact of the drought is very serious, and the wingless birds die while looking for water. During the day when the sun is at its strongest, the coastal waters of New Zealand are unusually warming, causing 500,000 mussels to be “burned to death” alive.

Marine scientist Andrew Jeffs said that as sea water heats up, mollusks in the waters around New Zealand are facing threats and even appear to be on the verge of extinction. There are some fishes and other creatures that can quickly”flee” to other seas, and those that can’t escape, may suffer from extinction. Scientists even predict that as temperatures continue to rise, mollusks will soon disappear completely from New Zealand.

The massive burning of fossil fuels makes the climate too hot, too humid or too dry, making certain species unable to survive Go on. Nearly half of the world’s terrestrial mammals (excluding bats) and nearly a quarter of bird habitats have been severely affected by global warming.

If the trend of climate warming does not decrease, more organisms will become extinct in the future, and the earth may become a”fireball”. As Hawking predicted, the earth will become like Venus, and the surface temperature will be as high as 460°C, and humans can no longer survive.
