What's the situation? We are talking about global warming, why is the earth cold on the other side, in the end is the direction of our earth getting cold or hot? Some people say that our earth will become hotter and hotter, and eventually it may go to the "fireball" era, and the state may become a "deserted" celestial body like Mars, without any living body. Others say that there is no need to worry, global warming is a "hoax", and our planet is not getting hot.
Many scientists have also said that in the future, our earth may gradually move towards the Xiaoice river period, and it will become colder and colder. Therefore, this has formed a variety of controversial topics. And, again, the question arises, is that antarctica has another "coldest winter on record" in 2021. Is this another example of the opposite? Let's take a step-by-step look.
<h1 class="pgc-h-arrow-right" data-track="18" > is the Earth getting colder or hotter? </h1>
From a scientific point of view, it is true that the scientific consensus is "earth warming". According to statistics, the average temperature of our earth has been more than 1 degree higher than the average temperature before industrialization, which means that the data directly proves that the earth is getting hotter, and we cannot deny it.
And with the continuous emission of greenhouse gases by human beings, a new round of high temperatures will likely appear again, and 2021 has the potential to have the hottest year on record, and carbon dioxide emissions have once again hit a new high.
Therefore, from the perspective of the greenhouse effect, global warming is still continuing, and the knock-on effect is still developing. And under the global warming, sea levels have risen, storms, rainfall, etc. are also frequent, and the intensity has also increased a lot. So as long as we don't change the climate, our planet will only continue to heat up.
The 2021 climate report also points out that our planet is warming and there is no sign of cooling. So the scientific consensus is warming, and there must be factors in Antarctica in 2021.
<h1 class="pgc-h-arrow-right" data-track="17" > turned out to be true! Antarctica had its coldest winter of 64 years</h1>
We all said above, the earth is warming, and there is a rare cold winter in the Antarctic, what is the matter? According to the Washington Post, monitoring data from a research station on the Antarctic Plateau between April and September showed extreme temperatures of minus 61 degrees Celsius, the lowest temperature recorded since 1957, about 2.5 degrees celsius lower than the average temperature of the last 30 years, which is quite rare.
Previously, the coldest winter was recorded at minus 60.6 degrees Celsius in 1976. So it directly became the coldest winter in Antarctica in 64 years.
So why is it so cold? Doesn't it mean that the Xiaoice River period did not enter? What's going on here? According to the analysis, in fact, antarctica this year is not so cold, in July, the antarctic also appeared the hottest July, and there is an extreme cold, through the analysis, may be because of the strong polar vortex caused by the climatic chain effect, strong polar vortex led to more ozone depletion in the stratosphere, thereby further strengthening the polar vortex.
Therefore, in the end, it is because of the effect caused by the polar vortex, which is also an extreme climate phenomenon change. Moreover, under the perspective of global warming, the impact of extreme whirlpools is also increasing. In the past year, there have been many cold waves in the Asian region, also because of the Influence of Arctic sea ice, Arctic whirlpools and other factors, so it has led to the continuous development of cold winter low temperatures, but as long as the chain effect of polar whirlpools stops, then the temperature will reverse, which is mutual.
Therefore, the coldest winter in Antarctica in 64 years is actually an extremely low temperature that lowers the overall temperature, of course, this low temperature is also caused by an abnormal climate phenomenon, not caused by continuous cooling, so it still illustrates the abnormal pattern of atmospheric response. And here we have to explain, although our human consensus is that the earth is warming. But from a geological point of view, we are not in the "warm period" of the Earth.
<h1 class="pgc-h-arrow-right" data-track="12" > experts say humans are in the middle of the Great Ice Age</h1>
According to Wu Huiting, a geology expert at China University of Mining and Technology (Beijing), from a geological point of view, the long-term low temperature of the atmosphere and the surface of the earth in the history of the earth has led to a significant expansion of the polar and mountain ice sheets, and even the period covering the entire continent is called the Great Ice Age, and the time scale to measure the Great Ice Age is one million years, since the formation of the Earth, there have been at least 5 Great Ice Period periods, and in the Great Ice Age, there is another "Greenhouse Period" or "Warm Period" that geologists call.
During this period, our planet could not see glaciers at all. However, in the evolution of the Great Ice Age, our planet's "Great Ice Age Period" will last for more than ten million years. Therefore, we can also see the arctic and south pole glaciers of the earth, which are actually still in the "great ice age" of the earth.
And the earth's ice age is even colder, the earth will be a "snowball" state, so, in fact, we humans are really in a big ice age, there is no big snowball event, because human beings live in about 11,000 years of an inter-ice age.
The average annual temperature is now 15 degrees Celsius higher than the peak of the Quaternary Ice Age, about 18,000 years ago, and scientists expect that the next ice age will arrive in about 90,000 years, and the "thousand miles of ice" world will come again. So there are tens of thousands of years before humanity re-enters the real cold thing, and that's the general situation. Relatively speaking, the warming we are talking about is just a "small episode" during the Great Ice Age, and this is the general situation.
