By February 2024, another alarm sounds, the alarm sounds! Could it be that the planet will soon become a miniature glacier, into an extremely cold world?
According to a new report on AMOC published in Science Advances, AMOC is on the verge of collapse from a physical point of view, and if AMOC collapses, then it means that the planet is likely to be "transformed" into a land of ice and snow.
What's going on? We'll see more details in the future, and this change is likely to have devastating consequences, so let's take a look at it step by step.
First of all, explain what AMOC is.
Many people don't know much about AMOC, but when it comes to the Atlantic Meridional Reversal Flow, many people know it, so what exactly is it?
The Atlantic meridional reversal flow is the most critical link in the global cycle, a key link in the ocean thermal cycle, and a key link in the global cycle.
The Atlantic water flows from south to north to high latitudes, creating a sinking branch at the North Atlantic, and then returning to the southern part of the South China Sea at the bottom, where it slowly moves upwards under the action of Ekman pumping by the Antarctic Circumpolar Current.
Because that's a big impact. The AMOC transports heat from lower latitudes to higher latitudes via ocean currents, redistributing the global heat and making the coasts wetter and warmer.
And, logically, when AMOC becomes weaker, this heat energy disappears and cannot maintain the stability of the planet.
But recent studies have shown that AMOC attenuation reduces heat transfer at the surface, increasing heat at the surface, which in turn causes global warming, which is not a good thing.
The main purpose of this issue of the study is to explain the anomaly of the AMOC, once the AMOC collapses, then the global weather will change, leading to a new kind of extreme weather in the world.
In other words, with global climate change, AMOC will collapse, and once AMOC collapses, it will cause the earth to enter an abnormal polarization, which is not beneficial to both sides, and the only way is to let the earth continue to develop steadily, let it continue to exist, but now it seems that this is impossible.
Since the planet is unstable and people are not really trying to protect it, climate change is still ongoing, and new research is approaching a tipping point.
Yes, the planet is heating up, there's no doubt about it, especially in 2022, which, as everyone knows, was the "hottest year ever".
According to statistics, this year is the warmest since 1951, with an average temperature 145±0.12 degrees Celsius.
As a result, the planet is warming, and in January 2024, there will be a new record: in January 2024, the temperature of the Earth's surface will rise to 1314, 0 higher than the previous hottest January 202212, which is higher than the pre-Industrial Revolution average temperature from 1850 to January 190066℃。
You see! All the data shows that the world is warming, and the same is true for the AMOC.
Therefore, as the planet heats up, the rate of AMOC collapse will get faster and faster.
René van Westen, a meteorographer and oceanographer at Utrecht University in the Netherlands, said: "We are close to collapse, but we are not yet sure how close it is. ”
But there is no doubt that it will be a tipping point, so the new study predicts that AMOC will not stop until decades later, rather than hundreds of years, as previously predicted.
Scientists have warned that the Gulf Stream will collapse as soon as 2025, when all of Europe will be frozen, and in the meantime, a series of values suggest that the power of the cycle will continue to weaken until it reaches a critical "tipping point" where it will eventually collapse.
The average temperature in Europe has dropped by about 1 degree Celsius in 10 years, and in some places by more than 3 degrees Celsius in 10 years, which is much higher than today's global warming rate (02 degrees Celsius 10).
In addition to these, Arctic glaciers will continue to move south, causing temperatures in the Southern Hemisphere to rise, leading to changes in the world's precipitation patterns and devastating the Amazon rainforest.
Other scientists believe that this will lead to a worldwide shortage of food and water. Tim Renton of the University of Exeter also said, "The study strongly suggests that the AMOC is approaching a tipping point, based on early warning signals based on a strong physical foundation."
In fact, this is not the first time that there have been similar statements, as early as 2021, Niklas Boers of the Environmental Impact Institute in Potsdam, Germany, said: "There is a clear signal of fluctuating currents, and this event is too relevant for us to drag on any longer." ”
At the same time, the journal Nature also published a study on AMOC in 2023, which concluded that AMOC is likely to collapse. So, the matter was decided.
Could it be that the earth will soon turn into a small glacier, into an extremely cold river?
According to their research, if the planet does collapse, there is a good chance that the planet will fall into a small ice age.
When Europe is in extreme cold, the rest of the planet will also be affected, turning into a small glacier, and changes in AMOC are important factors in determining whether the global climate will change dramatically.
Of course, I would also like to remind you that there is no contradiction between this and climate change.
Why say what Xiaoice River, why say that the earth is cold, it sounds like "the head is the way", but in fact, these two concepts are not contradictory, because climate warming is the key to AMOC.
At that time, the global cycle will change dramatically, do you think it will change? Therefore, the two are not contradictory, but complement each other.
