In 2021, our planet's climate change is still complex, and global warming is still evolving. According to the European Union's Copernicus Climate Change Service, with the increase in the concentration of carbon dioxide, methane and other gases in the atmosphere, the greenhouse effect in 2021 has not stopped.
And it became the seventh warm year in global history. The average temperature in 2021 is 0.3 °C higher than the average temperature in the base period (1991-2020), and 1.1 °C-1.2 °C higher than the average temperature in pre-industrial 1850-1900 years.
It has to be said that the warming of our planet is still happening. And the average concentration of carbon dioxide in the atmosphere reached 414 parts per million, and methane concentration also reached record levels. Therefore, we should make changes to greenhouse gases and not continue to emit them arbitrarily.
If this continues, otherwise the climate may affect all life on the earth, and extreme climate phenomena will also make it difficult for life on the earth to survive, which has become very common. High temperatures, droughts, strong storms, heavy rainfall, etc. are all affecting the survival of life.
However, this is a temperature change monitoring for the "outside of the Earth", and the greenhouse effect is not about the earth's interior. But there is a different situation in the interior of our earth, what is the situation? That is, the study pointed out that the cooling rate of the Earth's interior is much faster than expected, yes, you did read it correctly, that is, cooling, what is the situation?
The earth's interior is actually getting colder? Will this eventually lead to a cooling on the outside of the planet, leading the planet into an era of cooling? Indeed, it became a site of controversy again, and the study was published in the journal ScienceDirect.
For a long time, there have been studies of the earth's interior, but there is no definitive data to say that our earth's interior cooling has been pointed out, but what exactly is the pattern, and how fast, is difficult to explain. And most of us understand that our earth's interior is a huge center of thermal activity, such as mantle convection, plate tectonics, and volcanic activity, which will bring about changes in the earth's interior.
While the study found cooling in the Earth's interior, how long it may take for this sustained cooling to stop the aforementioned thermally driven processes, the study found a point.
The researchers pointed out that there is a "thin film" between the Earth's interior, which they call the "boundary layer", which is mainly formed by the mineral bridgmanite, ETH professor Motohiko Murakami and its research team, by developing a complex measurement system, made measurements of the "boundary layer", and found that the thermal conductivity of bridgmanite was about 1.5 times higher than the hypothesis. Thus, the heat flow from the center of the earth into the mantle is also higher than previously thought.
Larger heat flows, in turn, increase mantle convection, accelerating the Cooling of the Earth. It's actually an internal "energy conversion" process, which can lead to plate tectonics maintained by the "convective movement" of the mantle, which is faster than the researchers expected based on previous heat conduction values.
So, the researchers estimate that once post-peroxides appear at the core-mantle boundary and begin to dominate, the cooling of the mantle may be further accelerated, as the thermal conductivity of this mineral is even higher than that of bridmanite, which is why the cooling of the Earth's interior is much faster than expected.
Of course, this study is an affirmation of the occurrence of cooling in the Earth's interior, and since the formation of the Earth, the Earth has been releasing a lot of heat from the depths of the Earth to the surface, which will be said to be faster than expected.
Will the Earth's internal cooling, and faster than expected, trigger external cooling? What causes the Earth's surface to cool down? The earth's interior and exterior can also be regarded as a "circulatory system".
But from the surface of the earth unilaterally, the earth is heating up, as we said earlier, the atmosphere warms, the surface temperature is rising. The cooling of the Earth's interior, according to the paper, is also due to the transformation process of releasing energy.
Through the influence of plate movement, volcanoes and other factors, more heat may be released. Therefore, if it is said that cooling, in this regard, there is no effect. That is, the cooling of the earth's interior has no effect on the earth's surface. Even if we say that the atmospheric cycle does not occur in the earth's internal circulation, so it does not affect the climate phenomenon on the earth's surface, at least this conclusion does not appear.
Will the Earth cool down completely? How long will the Earth live? In fact, Science World in 2011 No. 1 has explained the cooling of the Earth, although it is pointed out through speculative data that the temperature at the center of the Earth has dropped by about 500 ° C (about 500 degrees) since the beginning of the birth of the Earth.
But this is only the tip of the iceberg for the "strong temperature" in the Earth's interior. How much energy there is in the earth's interior is unknown, and through the explanation of the sun, the sun will one day go to the "end of life", thus affecting the earth.
The Sun is a yellow dwarf, which has long been studied, and the lifespan of a yellow dwarf is about 10 billion years, and after about 5 to 6 billion years, the Sun will come to the end of its lifespan. At this time, the earth may be swallowed up by the sun. So the Earth will no longer exist.
That is, the Sun may have wiped out the Earth before it cooled. Therefore, the life of the earth is still billions of years, and we may not wait for the day when the earth will completely cool down, which is the general situation.
