The issue of the global warming effect has been lingering in our ears. Due to our massive burning of fossil fuels, deforestation and other acts of destruction of nature, it has led to a sharp increase in carbon dioxide, global temperature rise, sea level rise, glaciers and permafrost began to melt, This not only destroys the balance of the natural ecosystem, but also affects our life.

However, when we think that the temperature will continue to increase, the winter of 2021 seems to be a little different. The cold winter is long. What is the reason for the cooling of the earth?

Some scientists have discovered that the Antarctic Ocean is "absorbing carbon" on a large scale. It is estimated that the Antarctic Ocean absorbs about 530 million tons more carbon dioxide than it releases every year. From this point of view, the overall emission of carbon dioxide on the earth will be greatly reduced, and greenhouse gases can be solved. Is this a good thing?

The Southern Ocean is the ocean surrounding Antarctica and the only ocean on Earth that completely surrounds the Earth but is not divided by continents.

Why is the Southern Ocean absorbing so much carbon dioxide?

The ocean itself can absorb carbon dioxide. About 93% of the carbon dioxide on the earth will circulate into the ocean, so it is also called "carbon sequestration tank" by scientists.

The ocean will absorb it in two ways. One is that carbon dioxide is soluble in water. 71% of the earth is covered by oceans. It is conceivable that its ability to absorb carbon dioxide will not be weak; the other is the ocean dominated by algae Organisms can perform photosynthesis and absorb carbon dioxide. You must know that the amount of carbon dioxide absorbed by photosynthesis of algae is the largest amount of carbon dioxide absorbed by plants in the world.

The unique geographical location of the Southern Ocean brings it a strong westerly wind, which will make the sea rough and allow carbon dioxide to dissolve into the surface of the sea. However, when the weather is calm, the carbon dioxide will sink to the bottom of the sea and be absorbed by marine life.

You know, the Antarctic Ocean is located in Antarctica, which is rich in krill. According to rough statistics, the number has reached 1 billion tons, and krill feed on algae, so the amount of algae in the Antarctic Ocean can be imagined up.

Is there really less carbon dioxide?

The cooling we perceive is just a drop in the bucket for the world. Data show that the global concentration of carbon dioxide will reach a record high in 2021, and the temperature in China will also be 1 degree Celsius higher than in previous years. The discovery of large-scale "carbon absorption" in the Southern Ocean has only slightly slowed down the continuous warming of the earth, and global warming is still continuing and has not stopped.

We must not be affected by the hot and cold weather for a while. The earth has experienced repeated cycles of cold and warm for billions of years, although we cannot judge global warming based on the data of the past few decades. It is an irreversible conclusion, but the action of energy conservation, emission reduction and low-carbon life must continue.

Fortunately, carbon dioxide can now be artificially synthesized into starch and gasoline. We believe that through the power of science, we can change the world. What do you think about this?
