Is the earth going to "cool down"? Scientist: It is absorbing heat crazily, and the climate may change drastically in 2021
In science, there are two opinions about the future changes of the earth. The first is that the earth may become hotter and hotter in the future, and the second is that the earth may enter the Little Ice Age in the future. These two The scientists who make the statement all stand from different positions. They say that the earth is getting hotter, mainly based on the fact that the earth is continuing to warm. At the same time, the earth’s greenhouse gases are still intensifying. This is undeniable. In 2021 Carbon dioxide concentration in May also reached a record high again.
In May, the concentration of carbon dioxide in the atmosphere climbed to nearly 419ppm, which is very rare. The temperature of the earth will inevitably rise. To say that the earth is about to enter the Little Ice Age is mainly defined based on changes in sunspot activity. This is the general situation. According to a new study released by NASA and the National Oceanic and Atmospheric Administration in June, our earth has another "abnormal" pattern.
Research on the earth’s “crazy” heat absorption has been published in the journal Geophysical Research Letters. The research directly points out that the earth’s heat absorption from the atmosphere is about two times what it was 15 years ago. times, so the earth is absorbing heat "crazily", mainly due to changes in the earth's climate, and the heat absorbed by the earth is also the excess heat of the earth's "balance", which is equivalent to saying that the energy of the earth has already Lost "balance". Some of the energy is "circulated" by the earth itself, and some is "lost" outside.
This heat absorption analysis is from 2005 to 2019 (that is, within 14 years). The difference between the solar energy absorbed by the earth and the energy reflected back to space roughly doubled during this period, so this result is very "surprising". Once this imbalance continues to grow, then the future climate will It becomes even more extreme, and may even lead to catastrophic problems that are difficult for humans to imagine.
Now everyone can see that in a state of climate "imbalance", we see a lot of extreme climates, such as high temperature, drought, heavy rainfall, strong storms, etc. "all over the world" "raging" and getting crazier every year. However, when some people see this incident, they may think of a question, that is, the earth is absorbing heat "crazily". Will there be less heat in the atmosphere, and the temperature of the earth will drop? Is this the case? Woolen cloth.
In fact, this understanding may be different from others. The reason why the earth absorbs heat "crazily" is mainly because the earth has too much "thermal energy". Under the continuous emission of greenhouse gases by humans, the earth The heat at the "balance point" itself will exceed the normal level. Scientists call it a "positive imbalance." At this time, the excess heat comes from the "global temperature increase" which is too high, because The earth cannot balance this part of the heat.
So everyone has a misunderstanding. The earth is absorbing heat "crazily", but it is not that the earth's heat has decreased, but that there is too much heat, and there is no way. And everyone should also know that about 90% of the excess energy on the earth will eventually flow to the ocean, so the changes in the ocean area are also undergoing huge changes. From here, everyone should understand that the earth is not actually experiencing a "great cooling", but is experiencing a great warming, which is today's global warming model.
Human beings’ large-scale emission of greenhouse gases is one of the important factors in the earth’s “imbalance”. At the same time, the earth is “imbalanced”, causing “heat” to form a cycle process, which is most obvious in the ocean area. As the earth heats up, the increase in ocean temperature will lead to an increase in the amount of water vapor in the atmosphere, which will further increase the temperature. Therefore, the thermal cycle in the "ocean area" has already appeared. This is the trend of the earth today. It is really "getting hotter." , but there was no "big cooling" state.
In fact, we have now seen "signs" about the future climate of the earth. Not only the climate in 2021 may have changed drastically, but the climate in the past year has also been the same. The future climate trend has also undergone major changes.
In the past year, even extremely cold areas experienced high temperatures of 38 degrees, which is a historic high temperature in the Arctic. The fires in Australia burned for several months, affecting nearly 3 billion animals, etc. These are all related to climate. And in 2021, it seems that the climate is acting even crazier.
Extreme high temperatures, tornadoes, heavy rains, heavy rains, etc. are also stronger. The United States is also experiencing drought and extreme high temperatures that are rare in history. It must be said that under the background of global warming, human beings The climate problems we face are already quite serious. At the same time, this study now also warns that the amount of heat absorbed by the earth must be reduced, otherwise climate change will continue to worsen. Indirectly, it shows that the temperature of the earth really cannot rise any more.
The only way for mankind now is to reduce greenhouse gas emissions. It seems that there is no other way. Although mankind has proposed a plan to go to "Second Earth", it is obvious that there is no way to do it now. , so we have to wait a little longer.
