The Arctic, once a land covered with ice and snow, is home to a large number of polar bears and is also the main habitat of polar bears.
However, as the global climate continues to warm, the Arctic glaciers are melting faster and faster, and the land that should have been covered by thick ice is now bare, with bare soil and rocks.
Without glacier cover, bears will not be able to find a place to live, and the habitat of polar bears will be greatly affected.
However, the threat to the habitat of polar bears also indicates that the living environment of humans themselves will also be affected.
As the Arctic melts faster and the world's sea levels rise, it could flood coastal cities.
In this context, people have also begun to put forward the idea of freezing the Arctic, trying to slow down and suppress the melting rate of the Arctic through scientific and technological means, so as to protect the living environment of polar bears and human beings.
But what is the feasibility of freezing the Arctic?
1. Melting glaciers.
"Climate warming" is one of the most worrying topics in recent years, and a large number of data show that the global climate is indeed warming as a large amount of greenhouse gas emissions and accumulation year after year.
Melting glaciers is a very significant manifestation of climate warming, as glaciers are relatively cool, and once the temperature starts to rise, the glaciers will start to melt.
The Arctic, the world's largest glacier, has also been the most severely affected, and the Arctic is melting very fast, according to the latest data, the Arctic ice melts one million cubic kilometers in a year.
This data is also enough to surprise people, because the Arctic is melting faster than ever, and it is enough to make people sigh.
After the Arctic glaciers began to melt, the living environment of the bears has also been greatly affected, the polar bear has always been the "king" of the Arctic, and the main predator of the Arctic, but because the polar bear has a more mixed diet, so it mainly feeds on seals.
However, seals nest in burrows under the Arctic ice, but as the glaciers melt, many seals lose their habitat, leaving polar bears without food, so they naturally start to starve, and their survival is threatened.
The Arctic is the "restaurant" of the blue whale, but as the Arctic melts, the food chain of the blue whale will also break.
The algae and plankton beneath the ice are also used as food for whales and seals, so when it melts, the marine life beneath the ice will be fatally threatened.
However, the melting of the Arctic is not only affecting the habitat of animals, it is also likely to pose a threat to human beings, as the glaciers in the north begin to melt, and the global sea level is also rising, and the rate of increase is accelerating every year.
According to the latest statistics, Arctic glaciers can melt enough glaciers to raise global sea levels by one centimetre in a year, which is also very worrying.
And as the global sea level rises, coastal cities near the Arctic may also be submerged, and the global population distribution will also change.
2. Freeze the Arctic.
In the face of such a situation, some scientists have put forward the idea of "freezing the North Pole", so what about freezing the North Pole?
In fact, the principle of freezing the North Pole is very simple, which is to let the temperature over the North Pole drop again, and then stop the warm sea water from flowing into the North Pole.
The reason why a glacier melts is because it is exposed to external heat, so it keeps melting.
If the temperature over the Arctic drops again, the glaciers will not continue to melt and the glaciers will continue to grow.
Nowadays, the main way for scientists to freeze the Arctic is to inject large amounts of sulfuric acid and other substances into the sky over the Arctic, and then it is necessary to set up some ice storage banks on the ocean near the Arctic to store ice cubes.
So is such a technical solution feasible?
The most effective way to bring the temperature off the Arctic is to allow solar radiation from the ground to reflect back into space.
And these radiation requires a large amount of sulfuric acid and other substances to absorb, so the scheme proposed by scientists is also feasible.
In addition, to prevent warm water from flowing into the Arctic, it is necessary to set up some ice storage near the Arctic to store ice.
This would stop the flow of warm water into the Arctic, so the solution proposed by scientists is also feasible.
But there is a problem with this solution, that is, the amount of work is too large, and the cost is also very high.
3. Treat the symptoms but not the root cause.
In fact, this plan is only a palliative treatment, under the current level of human beings, it is impossible to permanently freeze the Arctic, but it can delay the melting rate of the Arctic for a long time.
Therefore, if you really want to solve the problem of climate warming, then you should start from the source, that is, reduce greenhouse gas emissions.
Greenhouse gases are mainly produced by human beings in production, life and travel, so human beings need to reduce greenhouse gas emissions.
So what kind of gas is called a greenhouse gas?
Greenhouse gases mainly include carbon dioxide, methane, nitrous oxide, etc., which can absorb thermal radiation from the earth's surface and then propagate them to the atmosphere, so that the earth's temperature continues to rise.
Carbon dioxide is the main component of greenhouse gases, and the amount of carbon dioxide produced by humans in production is also the largest.
In addition, there are some gases such as: freon, trifluoromethane, chlorodifluoromethane, etc., although they are produced in small quantities, but they are much more destructive to the ozone layer than carbon dioxide.
Therefore, human beings should minimize the use of these gases that will cause damage to the ozone layer in production, and promote the use of clean energy, such as solar energy, wind energy, etc., to reduce industrial emissions and reduce the impact on the climate from the source.
epilogue
Protecting the Arctic requires global environmental protection activities, human joint efforts, the reduction of greenhouse gas emissions, and the promotion of clean energy.
Although the current environmental protection measures have played a certain role, they have not stopped the melting of the Arctic, so it is necessary to reduce greenhouse gas emissions at the source in order to completely solve the problem of climate warming.
