For decades, global temperatures continued to rise due to excessive greenhouse gas emissions caused by human activities, and greenhouse gases continued to affect the energy balance in the atmosphere until around 1860, when the rate of global warming far exceeded the scope of anthropogenic influence, and the global average temperature increased by 1.2°C year-on-year.
Climate change has become a common concern of all countries, and the United Nations has convened global climate change conferences on this issue many times to formulate various plans to reduce greenhouse gas emissions, but global warming has not stopped there, and even brought warnings of increasing extreme weather.
In 2021, the average continental temperature was nearly 1°C higher than normal, and the global greenhouse gas concentration also continued to rise, making the situation of mitigating the greenhouse effect more serious.
However, nature does not seem to agree to such a development trend, and a relatively powerful "carbon absorption zone" has emerged in the world.
The main factor of global warming
Global warming is one of the main factors of the earth's climate change, the earth is in an upward warming cycle, but at present, it seems that this warming trend seems to achieve no significant progress, especially in industry, especially after World War II, the rapid development of industry around the world, mainly by burning fossil fuels, emitting a large amount of carbon dioxide in a short period of time, of which carbon dioxide emissions account for a large proportion.
Before 1955, the global carbon dioxide emissions from human industrial activities and biocombustion were mainly in the Spanel and Inner Mongolia regions, and the amount of carbon dioxide greenhouse gases emitted was also low.
However, with the advent of the industrial age, the use of fossil fuels has become more and more widespread, and the annual carbon dioxide emissions are also rising year by year, and at the same time, the carbon emissions from biocombustion have also increased significantly due to large-scale reclamation of wasteland.
Due to excessive greenhouse gas emissions, the energy balance in the atmosphere is disrupted, after the solar radiation enters the earth's surface, the energy absorbed by the earth's surface will be converted into the surface temperature, the surface air temperature will rise, and then the heat energy will be released into the atmosphere, and the greenhouse gas density will increase, so that the temperature of the earth's surface will continue to rise, forming a greenhouse effect.
Scientists began to study the greenhouse effect, put forward the concept of greenhouse gases, and proved that the greenhouse effect caused by greenhouse gases such as carbon dioxide is the main factor, and the first thing to solve is to solve the problem of excessive greenhouse gas emissions, which is naturally to reduce the emission of greenhouse gases such as carbon dioxide.
It is precisely for this reason that the United Nations has formulated emission reduction plans to reduce greenhouse gas emissions many times, and has also convened global climate change conferences many times to discuss how to better reduce greenhouse gas emissions.
In addition, as the trend of global warming continues to increase, many countries are continuing to plant trees and reduce other greenhouse gas emissions as much as possible, and global warming has been going on for decades, and countries are also continuing to reduce emissions.
However, even with so many international actions, the trend of global warming has not been reversed or improved, and the threat of global warming continues, so we should continue to pay attention to the problem of global warming, and we should not lose attention to the problem of global warming because it has not been improved.
Carbon absorption occurs in the Southern Ocean
Thanks to the unremitting efforts of scientists around the world, a powerful "carbon absorption zone" has recently emerged on the earth, so that people around the world can see hope at once.
All this happened in the Southern Ocean, and it is reported that there is a very large "carbon absorption area" in the Southern Ocean, and the area of this carbon absorption area is very large, which is much larger than other carbon absorption areas.
Even 90% of the contribution comes from carbon absorption in the Southern Ocean, which has surprised scientists around the world, because many plants on the earth, such as trees, herbaceous plants, etc., can absorb carbon dioxide, but the total land area of the world is relatively limited, so sodium can play a very good role.
But the effect that can be played on land is still very limited, and there is a very good example on the mainland - Qilian Mountain.
Along this "green barrier", carbon dioxide is isolated by the Qilian Mountains and other major mountain systems, which also effectively improves the climate and environment of the continent, but if the plants on land alone absorb carbon dioxide, it will be a drop in the bucket.
About 1.3 billion tons of carbon are absorbed from the atmosphere into the sea every year, while the Southern Ocean releases about 770 million tons of carbon each year, which means that the Southern Ocean absorbs 530 million tons more carbon than it releases each year, and this huge number has shocked scientists around the world, and some scientists can't believe that this data is real.
Moreover, the emergence of super-large carbon-absorbing areas is more like the efforts made by the Southern Ocean to regulate its own activities, and the imperceptible changes of the earth have had a great impact, which shows that the earth has a magical power, which makes people understand nature further, and know that nature has a strong vitality and self-regulation ability.
Can the Southern Ocean Achieve the Earth's "Great Cooling"
The carbon absorption phenomenon of the Southern Ocean has indeed provided help to the world, because they have a planned and regular carbon absorption effect, thereby reducing the carbon content in the atmosphere, effectively reducing greenhouse gas emissions, and at the same time reducing the phenomenon of ocean acidification and reducing the destruction of marine ecosystems, so it can be said that the carbon absorption of the Southern Ocean has a positive effect on controlling global warming.
However, the carbon absorption phenomenon in the Southern Ocean can only reduce the carbon content of the atmosphere, but not the phenomenon of "great cooling" of the earth, and the temperature of the earth's surface layer will not be reduced by reducing the carbon content in the air, but will rise due to global warming, and this upward trend will not change.
Therefore, the carbon absorption phenomenon in the Southern Ocean cannot "cool down", global warming is still continuing, and the earth's temperature is still rising, bringing more natural disasters, so human beings must immediately formulate better measures to reduce greenhouse gas emissions, otherwise, it may bring very serious consequences.
And the reason for all this is due to the overexploitation of the earth's resources by our human beings, emitting too many greenhouse gases, and finally breaking the greenhouse effect, and the living standards of human beings will also be affected, and more and more people will be displaced, and purgatory on earth will appear.
Therefore, all countries in the world should take the issue of global warming seriously, and only by working together can we make the earth cleaner, the recovery of nature faster, and the life of human beings will be better.
epilogue
Although there is now a phenomenon of carbon absorption in the Southern Ocean on the earth, it is also a matter of recent years that carbon absorption has occurred in the Southern Ocean, so this phenomenon is still developing, and it cannot be said that the problem of global warming will be solved if you donate generously, and the problem of global warming still needs to be solved by yourself, and you can't hope for the carbon absorption of the Southern Ocean.
In addition, the Southern Ocean is only a "carbon absorbing area", and it cannot be said that the problem of global warming can be solved by it, although the Southern Ocean can "help", but the greenhouse gas emissions in other parts of the world are still a bad situation, so we still have to weigh it ourselves, and we can't all hope for the Southern Ocean.
