Cows and sheep burping, farting to release methane, wild boar foraging to destroy the soil will increase carbon emissions, global warming is how it comes? Of course, this is only based on part of the research, and the most important thing is that the greenhouse effect caused by humans is the most obvious. Human emissions of pollutants to the atmosphere are the most important, so these greenhouse gases caused by organisms can only be regarded as a part of them, and there is no way to compare them with humans.
However, everyone is still a big controversy about the changes in the earth, especially the "hot and cold" problem of the earth, because the consensus of the scientific community is global warming, but under the global warming, the study found that there is still an "ice age". Isn't it right for the planet to warm? Let's take a look at the situation.
<h1 class="pgc-h-arrow-right" data-track="16" > yes! Humanity is in the midst of the Great Ice Age</h1>
According to geological studies, since the formation of the Earth, our Earth has had at least many Great Ice Ages, and each Time the Great Ice Age has lasted for tens of millions of years. At this time, the North and South Poles of the Earth were covered by a large amount of ice, which could exceed 30% of the total surface area. Compared with the greenhouse period, the north and south poles of the earth are not covered by glaciers, so we can see that the earth and the north and south poles still have glaciers, which means that human beings are in the "Great Ice Age".
Scientists estimate that more than 85 percent of Earth's 4.6 billion-year history has been a greenhouse period, so the Great Ice Age is only a "brief evolutionary process" of this "greenhouse period" and there is nothing special about it. At the same time, the study also pointed out that each ice age also has its own evolutionary cycle, and not every time it appears, it is similar to the occurrence of a "snowball event", that is, we call the entire earth into an icy state.
So it's a misunderstanding. Humans are in the midst of the "Great Ice Age", the Quaternary Ice Age, and the ice sheets of Antarctica and Greenland are symbols of this ice age. So when will the next big ice age occur? Scientists predict that the next ice age will arrive in about 90,000 years, and the world of "a thousand miles of ice" will come again. So, the Planet is in the midst of climate change during the Great Ice Age.
<h1 class="pgc-h-arrow-right" data-track="15" > what is the case with global warming? </h1>
Indeed, it is not a "contradiction" to say that human beings are in the midst of the Great Ice Age, but the Earth is getting hotter and hotter? It is true that everyone may not understand it, in fact, as mentioned above, the "greenhouse period" is only a part of the "Great Ice Age". The warming of the earth is the biggest change under the influence of human activities, leaving aside the natural evolution of the earth, the rest is the greenhouse effect of human beings on the earth.
Since the era of industrialization, human beings have made the earth's greenhouse effect stronger and stronger through fossil burning, deforestation, etc., and human activities have broken the "carbon cycle" maintained by the earth's organisms for hundreds of millions of years, which has triggered a chain effect of climate and led to stronger and stronger climate evolution. The earth's average temperature is also getting closer and closer to the 1.5 degree critical point of the Paris Agreement, and according to the report released by the United Nations, the global average temperature will rise by 1.5 degrees Celsius in the next 20 years.
At the same time, extreme climates under the influence of global warming will also occur frequently and increase in intensity. So, people are also worried about climate change in 2021. However, combined with the above statement, human beings are in the "Great Ice Age", which also shows that the earth in 2021 is in the middle of the "Great Ice Age", so will it be colder this winter?
<h1 class="pgc-h-arrow-right" data-track="11" > cold winter warning coming? </h1>
Considering that human beings are in the midst of the "Great Ice Age", and considering the problem of global warming, the problem of "hot and cold" of the earth, it is true that the climate change of the earth is more complicated. And will the Earth be colder in 2021? From the perspective of global warming, the average temperature of the world is still high, so it will not become cold. But if it is winter, it is not surprising that it will become colder, in addition to the fact that the earth is in the ice age, global warming will also trigger a knock-on effect.
That is, extreme cold can still occur. At the same time, for the earth in 2021, there is another important factor, that is, the La Niña phenomenon that everyone has been talking about, in the time of the La Niña phenomenon, global warming can be suspended, that is, the warming or suspension of the earth.
Combined with the Great Ice Age, that means that the Earth may become cold, but this extreme cold is only "short-lived", and the above study also indicates that the next ice age will arrive in about 90,000 years, and the world of "thousands of miles of ice" will come again.
Therefore, it is unlikely that the earth will last for tens of thousands of years, after all, it will not reverse the trend of "short-term global warming". So global warming may trigger extreme cold, La Niña phenomenon may also trigger cold patterns, but it will not appear, only after the end of this year, and only after the end of winter, we can determine it, the data can point to this problem, this is the general situation.
So the big cooling of the earth that everyone is talking about, the possibility of a "double La Niña" phenomenon in 2021, getting colder, etc., are all speculative statements, and it is impossible to be sure, and everything is clear at the end of winter.
