Never expected that the reason why our earth entered the " Little Ice Age " seemed to have found its "eye" and it might have something to do with what we said " Earth and Moon Distance ".
from the Proceedings of the National Academy of Sciences (2022) released a new study pointing out that our earth has undergone many "distance changes" in the past 2.5 billion years, which has triggered a huge climate change on our earth, and this change is still relatively large.
Scientists have found the answer to the correlation through the rocks - sediments on the earth. So what is going on? Let’s take a look at the situation below.
The relationship between the earth and the moon
That's right, if you say that there is no impact between the earth and the moon, it will definitely be impossible. Let’s talk about a simple example and you will understand, that is what we call the “tide” phenomenon.
This phenomenon occurs more obviously in coastal areas and is a natural phenomenon. However, its appearance is closely related to the moon, and it is the moon. Under the interaction of the gravity of the sun, it triggers periodic changes in the earth's sea water. It usually fluctuates twice a day, and there are also fluctuations once a day.
Although it "interferes with" the influence of the sun, it also shows that the relationship between the earth and the moon exists.
So, changes in the moon can indeed affect the earth, and changes in the earth may also affect the moon. Of course, this change also brings obvious benefits to us humans, that is, the emergence of a tidal power generation system, which is similar to the principle of ordinary hydropower generation. By exiting the reservoir, the seawater is stored in the reservoir at high tide and preserved in the situation of potential energy.
Then, seawater is released at low tide, and the gap between high and low tide levels is used to promote the rotation of turbine to drive the generator to generate electricity.
So, humans can be said to have put the application of changes in the earth to the "extreme".
, the relationship between the earth and the moon has also had an impact on the climate change of our earth. In fact, you can also imagine from the tidal relationship that the climate impact on the earth also exists, but how to judge this "quantity".
Research: The moon has been away from the earth
The moon has been away from the earth How did this discovery? Earth's rocks - Sediments can calculate changes in Earth's climate. For the moon, humans have long made relevant deployments.
That is NASA (NASA) installed an instrument during the Apollo program to determine the correlation between the moon's changes. NASA has also clearly stated that the measurement of moon rotation can be increased by orders of magnitude.
and the accuracy is very high, making its change accuracy measure up to 3 cm. So, through its changes, we know that the moon has been away from the earth and is away from it with a change of 3.8 cm per year.
However, the changes between the earth and the moon, the scientific team found the ancient changes of our Earth by simulating the changes in Milankovic cycle in Karigini National Park in western Australia through the layered sediments with a history of the past 2.5 billion years through the mineral changes carried inside.
thus also found a law of climate change on our planet, and there is a change between the earth and the moon, whether it is the Little Ice Age, our extremely warm period, and humid or dry regional climatic conditions. So, its change may have triggered a fundamental change in our planet.
The reason why the earth entered the small glacier was found?
You really don’t want to say that, this study really gives a seemingly clear change.
In the Milankovic cycle, it describes one thing itself, that is, how the slight periodic changes in the shape of the earth's orbit and its axis direction affect the distribution of sunlight received by the earth over many years.
In this study, scientists discovered that the earth and the moon change every 400,000 years, 100,000 years, 41,000 years and 21,000 years. In this process of change, its climate response to our earth appears.
Because after this cycle of activity, the surface of our earth will undergo a climate change. This is also one of the reasons why Sahara Desert turns green periodically and the deep sea has low oxygen content. Among the stratified sediments, evidence of the earth's climate change caused by the change in the distance between the earth and the moon was indeed found. There is very clear evidence for these remaining sedimentary rocks , that is, rock deposition is repeated at intervals of about 10 cm and 85 cm, which means that periodic climate changes occur around 11,000 and 100,000 years.
So, this also forms the change process of the Earth's Little Ice Age and the extremely warm period. At the same time, the scientific team also discovered a problem, that is, we discovered that the moon was about 60,000 kilometers away from the earth at that time (this distance is about 1.5 times the circumference of the earth).
This will make the length of the day much shorter than what we see today, about 17 hours, rather than the 24 hours today. Therefore, this has a great effect on finding out the fundamental reason for the succession of the Quaternary Ice Age on Earth.
And this practical evidence can illustrate one thing, that is, a scientific team previously said that changes in the activity of the sun may trigger the emergence of the Earth's Little Ice Age.
And this will show the "actual" evidence we see, which further illustrates the distance relationship between the earth and the moon. The periodic changes may be the fundamental reason that triggered the earth to enter the Little Ice Age. However, there is no explanation for which time we are in at this time.
However, in terms of periodic changes, it means that the Little Ice Age may indeed appear on the earth in the future. So, it depends on whether the subsequent scientific team can give a speculative explanation.
Summary
Overall, although we have studied the changes in the distance between the earth and the moon, we have seen some reasons for the earth's climate change and discovered the changes in the Earth's Little Ice Age and the Extreme Warm Period.
However, this may require more evidence to answer. It can only be said that the change in the distance of the moon has an impact on the earth's climate. But it also has a loop process. Where the nodes of this loop process in the future are currently unknown, and this is the general situation.
