It is about to break through 420ppm! The concentration of carbon dioxide in the atmosphere has reached a new high. What happened to the earth?

Everyone hopes that their living environment is getting better and better, the temperature is suitable, the air is fresh and the scenery is charming. In this way, their mood will naturally become extremely comfortable, but the environment of the earth is deteriorating step by step, especially the climate, which has undergone irreversible changes in a short time.

What irreversible changes have taken place on the earth? The greenhouse effect is more and more obvious, the summer is getting hotter and hotter, the frequency of natural events is getting higher and higher, the winter is getting shorter and shorter, the polar glaciers are melting faster and faster, and the permafrost in the Arctic is collapsing more and more.

Why does the global climate change? According to scientific research data, the initiator of climate change is ourselves, because we are relentlessly releasing greenhouse gases into the atmosphere 24 hours a day, the most of which is carbon dioxide (CO2).

When it comes to CO2, everyone will be familiar with it. It often enters our stomach with cola and sprite, and then exhales from the respiratory tract with a lot of hot air. It can be seen that too much carbon dioxide in the air can really warm up and keep warm, but for a planet, it is not a good thing to keep warm too much.

In June, 20021year, the latest measurement results of atmospheric carbon dioxide (CO2) released by the National Oceanic and Atmospheric Administration (NOAA) of the United States showed that the level of carbon dioxide (CO2) has been soaring recently, and reached a record high again in May, reaching 4 19. 13(ppm), which is about to break through the 420 ppm mark. Earth.

You know, at this time, it is a global epidemic, and many enterprises have stopped working. If not affected by the epidemic, carbon dioxide (CO2) would have exceeded the 420 ppm mark. So people have lost confidence in the plan to control global warming.

We emit about 40 billion metric tons of carbon dioxide into the atmosphere every year. Yes, the earth's atmosphere is overwhelmed. Unless the global human carbon dioxide emissions are zero, the global greenhouse effect can be reversed, but in today's 202 1, this is obviously impossible.

According to the Keeling curve recorded by NOAA from 1958, the global carbon dioxide concentration level is rising steadily, from 3 10(ppm) to 4 19.5438+03 (ppm) in May this year, so it is very promising to break through the 420ppm mark in 2022.

May of 20021year became the month with the highest carbon dioxide level in more than 60 years. So, what is the impact of high carbon dioxide levels now? Compared with 1958, the annual average temperature has increased by 2~3, and the offshore platform has increased by at least 1 m, resulting in more frequent fires, more and more violent marine cyclones and more disastrous weather.

However, this is only the beginning. This is another warning from nature to human beings, which has aroused people's concern about the global climate. If it continues, the future carbon dioxide concentration will soon set a new record, and the earth will become a "fireball" sooner or later.

Speaking of fireballs, it reminds me of Venus, the sister planet of the earth, a planet that turned into a fireball because of out-of-control climate. Today, the dense atmosphere makes the temperature on the surface of Venus as high as 464, which makes it impossible for all life to survive. Even steel robots can only survive on the surface of Venus for a few minutes, which is terrible.

So will the future of the earth be like Venus, with a high temperature of several hundred degrees Celsius on the surface of the earth? Many scientists believe that if humans continue to emit a large amount of greenhouse gases, when the controllable threshold of the earth is reached, the earth will really become the second Venus.

In addition to the famous physicist Hawking's prediction that the earth will become a fireball in the future, Musk, known as the cosmic madman, also mentioned this matter, thinking that one day in the future, the earth's climate will become uncontrollable and the earth will become a fireball. Humans need to emigrate to other planets to get rid of the predicament.

Nowadays, the earth is getting warmer, but our greenhouse gas emissions are still high. No wonder there is a saying that the earth civilization may have come back several times, and human beings are just one of them. When civilization develops to a certain extent, there will be self-destruction Come to think of it, this statement makes sense.
