All of you are wrong? Whether the earth enters the extreme cold era or the super high temperature era, will the earth eventually be "suitable" for human habitation?

is right! This research has indeed surprised many people. If this is the case, it seems that our maintenance of the earth will have no effect. Anyway, the earth can eventually "regulate itself" within thousands of years.

What is the situation? Let’s take a look at whether everything we do is “futile” and is it really useless?

The "this level" known to the earth - warming

is right. No matter how the earth changes, we will try our best to change the climate - the warming trend cannot be changed. In 2022, the United Nations issued another warning that human beings may eventually move towards a "road of no return" and the world is facing the risk of "collective suicide".

This is a warning to the aggravated impact of climate change and the threat to human beings. And the climate pattern we see is also an increasing trend. The warming of the earth still exists. Even the development of the natural regulator of the earth, the La Nina phenomenon, has not allowed our average temperature to rise by 1 degree, so the enhancement of warming is very obvious.

Of course, the same is true for our country itself. Since 1951, my country's annual average temperature has shown a significant upward trend, with a temperature increase of 0.26℃/10 years, higher than the global average during the same period (0.15℃/10 years). It is a sensitive area for global climate change. 2012 to 2021 is the warmest decade in history in the past 70 years.

. Under warming, there are many various climate patterns, such as extreme high temperatures, strong rain and other phenomena, which are unevenly distributed in different regions, and the trend of change is also more extreme.

Therefore, the development of global warming has indeed had a "fatal" impact on human survival.

And even in 2022, due to the impact of high temperatures, at least 15,000 deaths in Europe may occur, which is the harm.

If the earth continues to warm, then in the end, human beings may not be able to escape becoming a "passerby" to the earth. This is not an "insensationalist", but the impact brought by climate change, which we can all see. When the climate evolves beyond the limits of human beings, it will be too late for human beings to find ways to reverse it.

doubt! Doesn’t this mean that the earth can self-regulate? Is it necessary to be afraid of global warming? This research is indeed very unique, so what is going on?

study: The earth can regulate its own temperature within thousands of years, really?

In fact, my country has also studied the self-regulation of the earth itself many times, and a problem has been mentioned here, that is, the problem of silicate weathering. The study is a research result from MIT and has been published in the journal Science Advances.

Through the study of the climate change model experienced by the earth, our earth has experienced the era of volcanic eruptions, the ice age, and also encountered huge changes such as solar radiation.

However, in the past 3.7 billion years, our life on earth has also changed accordingly. For life on Earth, we also make changes in rotation, including the theory that the earth has experienced the "five mass extinctions of organisms".

But has the earth become unacceptable to living? No, except for the replacement of life on our earth, the earth is still the same earth and is still habitable.

This is where the earth's self-regulation may exist, among which silicate weathering is the most important role. In the midst of huge changes in the climate, silicate weathering will slowly absorb the carbon dioxide in the atmosphere through chemical reactions, and then store it in marine sediments, thereby achieving the mechanism regulation of climate change.

In April 2022, my country also published results on climate change in the journal EPSL, which also explained that:

Continental silicate weathering affects the climate by absorbing atmospheric CO2. At the same time, the weathering process is controlled by climate factors such as temperature and precipitation, that is, the silicate weathering process forms negative feedback on climate change.

If that's the case, it can indeed provide a geologically constant "force" - to control carbon dioxide and global temperatures. This time, through a comparative study of paleoclimatic data recording global average temperature changes over the past 66 million years, it was also found that this pattern does exist, that is, the temperature fluctuations on the earth are suppressed on a time scale of hundreds of thousands of years.

So, the earth can regulate its own temperature for thousands of years, really?

really exists. This result uses actual data for the first time to confirm the existence of stable feedback, and its mechanism may be based on silicate weathering.

Of course, this conclusion is that the earth's self-regulation exists, which may be the regulation of silicate weathering. Therefore, this seems to be a "good news" for us humans. After all, under the climate change of the earth, this regulation is the best. This time, the regulation exists. That is really "good news".

The earth is not afraid of high temperature and extreme cold, and humans are in vain?

From the perspective of the regulation mechanism, it seems that there is no need to be afraid or worried. After all, the earth will put us in a condition of "adapting to living".

However, when we discovered this mechanism, there was also a situation, that is, if the time was slightly extended - as the earth's temperature fluctuated over a longer period of time, the ability of these fluctuations to be regulated in a geological sense becomes smaller, and there seems to be no recurring global temperature regulation ability on a time scale of more than 1 million years.

That is to say, this feedback mechanism exists and will disappear when the time span is too strong. In other words, there are time periods that exist stably, but there are also time periods that do not exist. It is impossible to judge whether , the geological era we are in. There is no data to prove that this mechanism has always controlled the earth's climate. This is the problem.

Isn’t that too high temperature or extreme cold? Is humans worrying about it in vain? Actually, there is still something to worry about.

is like high temperature. Although it indicates that global temperature fluctuates violently and the carbon flux entering and leaving the earth's surface environment remains relatively balanced output, global warming needs to be eventually offset by this stable feedback. Is our earth in this state? There is no direct evidence to explain it. Therefore, maintenance of the earth system is still necessary.

At the same time, for us humans, the average temperature on the earth has increased by about 1 degree, which many people can no longer bear. When the climate critical point of 1.5 degrees or 2 degrees is reached, can humans still bear it? This "node" may be unbearable.

And in 2022, many people can't bear the high temperatures of 40 degrees and above 50 degrees.

When the average temperature of 1.5 degrees and 2 degrees increases, a high temperature of 60 degrees or even 70 degrees may occur. Not to mention such a temperature, we humans may find it difficult for all living creatures living in water to survive.

What's more, we are all unknown how long the "self-regulation" mechanism of this earth will appear and how long it will last.

So, let’s stop by the “climate critical point” under warming. This period cannot be overcome. Even if the earth regulates itself, it is useless. The life on earth is gone, and only the next round of life on earth can experience it.

Therefore, if the earth is in high temperature and extremely cold, we still need to increase maintenance and cannot allow it to appear, because under these two extreme climate modes, it may be difficult for humans to survive. As we said above, it is similar to the extreme cold.
