What will happen to humans when Antarctic glaciers melt and prehistoric viruses break out?

We all know that the earth has a history of 4.6 billion years since its birth. In this long development process, the earth's environment has also undergone earth-shaking changes. With the constant change of the environment, many creatures have gone extinct because they are difficult to adapt to the new environment of the earth. The so-called natural selection, survival of the fittest, is exactly the case. However, with the Maya predicting the end of the world in 20 12, disasters will break out all over the world by 2020, and people are more concerned about the fate and future of the earth than ever before.

Looking back at the soul-stirring and devastating disasters in the 4.6 billion-year history of the earth, we are grateful and cherish the present earth even more. At the same time, we can't help thinking: how many lives are left on the earth for human beings to squander? What will happen to mankind once the earth systematically collapses? This problem is extremely worrying. As we all know, with the development of science and technology, the quality of our life is constantly improving, but the natural and man-made disasters suffered every year are also increasing year by year, and the language that the earth is about to be destroyed is circulating on the Internet from time to time. However, these rumors are not groundless, and mankind is indeed facing challenges from nature and the test of fate.

Since human society stepped into the process of industrialization, the word climate change has been related to human beings, and it is getting out of control. In 20 18, the American magazine Scientific Man published an article pointing out that since continuous atmospheric monitoring began in 1960s and 1950s, the atmospheric carbon dioxide concentration has increased faster in the last decade than in any other decade. At present, the concentration of carbon dioxide is about 35% higher than that before the industrial revolution. The concentration of nitric oxide is about 20% higher than that before the industrial revolution. The content of methane is about 2.5 times that before the industrial revolution, although many countries in the world are trying to reduce greenhouse gas emissions. But the concentration of carbon dioxide in the atmosphere is still at a new high.

In the past two years, some human scientists have found that the global climate has undergone disturbing changes. The content of carbon dioxide in the earth's atmosphere has reached the highest point since the birth of mankind. According to the data measured by the measuring station on Mauna Loa Island, Hawaii, USA, the atmospheric carbon dioxide concentration has reached 4 15 ppm, that is, there are 4 1 5 units of carbon dioxide in every110,000 units. This data has exceeded the highest record retrieved from Arctic glacier records in Earth's history. As we all know, the excessive emission of carbon dioxide will directly lead to the increase of the earth's temperature, and we will feel that winter is getting warmer every year. In summer, as netizens said, there is only a handful of cumin in the roast mutton in the nest, which shows how spicy it is.

However, this is only the tip of the iceberg caused by bad weather. The melting speed of polar ice sheets is six times that of 1990 s published by the British newspaper The Guardian in March this year. It is pointed out that 89 scientists from 50 international organizations around the world have found that the melting rate of ice sheets in the polar regions of the earth has exceeded six times that in the 1990s. This is by far the most complete scientific analysis. The conclusion is that if this continues, at least 400 million people will struggle in the flood disaster every year. Many coastal areas will face the disaster of being submerged because the sea level continues to rise. What is even more surprising is that in such an extremely cold area as the Arctic, there has been a high temperature of more than 20 degrees. Scientists predict that in 2050, the global14 glaciers will disappear from the earth.

As for the South Pole, almost all the ice has melted, and animals living in the North and South Poles are most directly affected. According to the statistics of biologists, if the global warming trend is not improved, the number of penguins will decrease by more than 85% in the future, which is a very terrible number. In the future, these penguins will be unable to find their original homes because of melting glaciers, and even stay in fewer and fewer places. Food in the ocean has become toxic and inedible due to a large amount of sewage and plastic waste discharged by human beings. Just after the baby penguin was born, she was poisoned by her mother's milk before she opened her eyes to see the world.

In recent years, due to the continuous disappearance of glaciers, some creatures in the Arctic can't find enough food to fill their stomachs. From the photos taken by some photographers, we can see that the disappearance of glaciers has seriously affected the survival of polar bears, and they can't find enough food. Polar bears have even reduced to collecting human garbage for a living, but the most terrible thing is yet to come.

With the disappearance of glaciers and ice sheets covering polar continents, creatures living in the Atlantic and Pacific oceans began to merge. Before the glaciers melted, Arctic creatures living in the Pacific Ocean and the Atlantic Ocean were blocked by thick ice sheets, forming relatively independent genetic systems, each lacking antibodies against the other's diseases. The disappearance of glaciers makes these marine creatures living in different areas encounter different diseases, which directly leads to the spread of some deadly diseases. Recent research shows that the melting speed of Arctic glaciers is accelerating due to climate change, and a deadly virus has begun to spread wildly among animals. This virus is killing seals and sea lions.

In fact, the virus appeared as early as 2002, when thousands of seals were killed. Scientists call this virus seal fever virus, referred to as PDV virus. After 2003, seals in the North Atlantic began to migrate because glaciers melted and disappeared. They crossed the ice to the North Pacific, which led to the spread of PDV virus in the North Pacific. Viruses are no less lethal than any natural disaster. It can cause a large number of animal deaths in a short time and affect animals for decades. You should know that animals themselves will produce special antibodies to some local viruses in the process of evolution. However, when foreign viruses invade, local animals often die because they have no antibodies.

With the melting of glaciers, PDV virus broke out again. A large number of seals died in the Arctic. According to biologists' research, the emergence and spread of PDV virus is directly proportional to global warming, which means that it is global warming that leads to the large-scale spread of PDV virus, resulting in the death of tens of thousands of seals. It is understood that PDV virus has not yet started a large-scale outbreak, but biologists have failed to think of corresponding remedial measures, and glaciers are intensifying melting. Tao Tao mentioned earlier that the sea level is rising rapidly as glaciers melt. According to the data obtained by 1 1 satellite, more than half of the ice in Greenland is losing at an alarming rate, and all of it is lost to the ocean, from 1992 to 20 17. The Greenland ice sheet and the Antarctic ice sheet lost an astonishing 6.4 trillion tons of ice, of which Greenland accounted for more than half. If the polar glaciers melt, the sea level will rise by 66 meters. You know, the tsunami in Indonesia only rose by 10 meter, so which countries do you think will be submerged? Of course, the lower-lying countries are the first to suffer.

The impact of the ice sheet on climate warming is lagging behind, at least for 30 years, so even if we stop discharging now, the glaciers in the polar regions are still melting rapidly. We can only find ways to reduce carbon emissions, try our best to stop global warming, and maybe there is a chance, otherwise the future is unimaginable, and climate change and its series of harms are imminent. According to the report released by the Australian think tank National Climate Recovery Center, if we do nothing, human civilization may stop or even collapse around 2050. For 40 years, scientists have been communicating the upcoming climate crisis to the world, but it is still difficult to get widespread attention, and even gradually submerged in the rolling wave of climate conspiracy theories. Now, with the earth's climate in crisis, scientists have no choice but to try hard to wake up sleeping humans. They made a detailed record of the earth's environment and climate for 40 years. These factors include energy utilization, surface temperature, population, deforestation, polar ice content, population fertility rate and carbon emissions. According to these data records, they finally summed up only one sentence, the climate crisis is coming, and we are facing a climate emergency.

Today, the population of the earth is still soaring at the rate of 80 million per year, the deforestation rate of the Amazon rainforest continues to rise, and the meat production continues to increase. Everyone is on the same earth, feeling the changes of the four seasons and everything. Sadly, although countless people have been clamoring for the climate crisis for 40 years, the final results are few. Researchers believe that in order to avoid the disastrous consequences of the climate crisis, we must reverse the current climate development trend, bury all the remaining fossil fuels in the ground, and change the concept from gdp growth and pursuit of prosperity to giving priority to meeting the basic needs of maintaining climate and ecological stability, thus improving human well-being. Thankfully, in the past decade, the development of solar energy and wind energy has increased by more than 300%. The reduction of fossil fuels has exceeded $7 trillion. Although the situation is complicated and the prospect is pessimistic, it is not hopeless.

At present, the only thing we can do as ordinary citizens is to travel with low carbon, put an end to waste, reduce the use of plastics and prevent the global climate from reaching a catastrophic critical point. This is not only protecting the earth, but also protecting our home. What do you think of this? Welcome to leave a message below to discuss.
