Earth itself capable of controlling its temperature – research
Scientists at the Massachusetts Institute of Technology have made a new discovery. According to this, the earth has its own system, due to which it is able to keep the global temperature in a stable and habitable range. When the world is facing the threat of climate change due to global warming, this discovery can be considered very good. But, it is surprising that at the moment the world is still not hopeful of getting rid of these challenges. Because, it may take millions of years for the earth to control its temperature by itself. Well it is true that through the mechanisms she has, she constantly pulls the climate from a state of complete destruction. But, our crisis does not seem to be averted by this.
How will today’s problem be solved?
This research is published in the journal Science Advances. According to a release issued by the university, Konstantin Arnscheidt, a graduate student in MIT’s Department of Earth, Atmospheric and Planetary Sciences, said, ‘On the one hand this is good, because we know that today’s global warming is gradually affecting the Earth’s surface. It will eventually die out due to a temperature stabilizing mechanism….But, on the other hand, it will take millions of years to happen, which means it will not happen fast enough to solve today’s problem.’
Many surprising changes were possible in 3.7 billion years
Researchers have found that there have been many surprising changes in climate over the past 3.7 billion years. For example, despite periods of global volcanic activity and ice ages, Earth has managed to sustain life back on it. That is, the direct conclusion of this research is that whatever changes are currently being seen on the earth due to global warming, they are not forever. But, the biggest question is how is it possible to let go of the present life with the hope that everything will become normal again.
What is the Earth’s mechanism for controlling temperature?
The question is how does the earth control its temperature by itself? According to MIT researchers, this happens through ‘silicate weathering’. Scientists think that the Earth’s carbon cycle is controlled through this process. However, this is the first time such a result has come in any research. ‘You have a planet that has seen a number of dramatic external changes in its climate,’ Konstantin says. But why, after all, was it saving lives every time? One argument is that we need some kind of stabilizing mechanism to always keep the temperature favorable for life. “But the data had never demonstrated that such a mechanism repeatedly controlled Earth’s climate,” he said.

How did scientists collect data billions of years old?
To confirm whether Earth does indeed have a temperature-stabilizing mechanism of its own, the team of researchers analyzed global temperature fluctuations over millions of years. Scientists are compiling this data using the chemical composition of ancient marine fossils as well as samples from preserved Antarctic ice cores. The research student explained that ‘this whole study has only been possible because there has been a lot of progress in being able to analyze these deep-sea temperature records.’ He told that ‘now we have ’66 million years old data, which is a gap of thousands of years’.
