Is the earth’s temperature getting colder or warmer?
After the formation of the earth, in the known exploration of mankind, our earth has experienced at least two "extremely cold earth" periods, which is what we call the "Little Ice Age", and for the new round The emergence of the Little Ice Age is often hotly discussed in the scientific community. For example, in 2019, the most talked about thing was that sunspots triggered the emergence of the Little Ice Age. However, due to the inability to accurately observe solar activity, Therefore, there is no clear statement yet as to what state the solar cycle has reached.
However, most scientists in the scientific community have also analyzed and explained that the appearance of small glaciers on the earth may not have anything to do with sunspots. The last small glacier may have been a coincidence. In the second half of 2020, another article was published linking solar activity to the Little Ice Age.
According to the journal "Proceedings of the Royal Society", this research can say that when the "extremely cold earth" climate phenomenon occurred in the past, it may have been caused by a severe lack of sunlight radiation in a short period of time. Once again linking solar activity to the question of the Little Ice Age, the report also alerts the scientific community to the dangers of pushing planets beyond critical thresholds.
That is to say, our earth may enter the Little Ice Age again, so after all, some scientific researchers still believe that our earth will enter a new round of the Little Ice Age. Of course, this is The explanation is based on the relationship between the earth and the sun. If we explain it simply, there is a relationship between solar activity and the new round of the Little Ice Age on the earth.
According to scientific reports, our earth is in the habitable zone. If the sun moves away from our earth on a certain day, then the earth will not be able to obtain more heat from the sun, and the earth will inevitably enter a small glacier state. , because when the water on the earth's surface cannot be maintained in liquid form, due to the reduction of heat, it can only exist in the form of ice, and thus freezes.
On the contrary, if it is too close, the liquid water will evaporate, and excessive radiation will not allow organisms to survive. In fact, this is a bit like what we are talking about today about the climate phenomenon of the earth. The earth is getting hotter and hotter. Many life forms on the earth are no longer able to withstand the extreme high temperatures and will eventually disappear or become extinct. Therefore, this also reflects the sun's It is of great importance to our earth. Once problems arise, it will inevitably be huge.
Researchers from the Massachusetts Institute of Technology in the United States also provided explanations through model reference data, believing that the earth once became very cold due to the lack of sufficient solar radiation and experienced an "extremely cold earth" period. Now that we know this has a probability of happening, we need to predict whether it will happen again. Therefore, this "extremely cold" critical point is still possible, which is quite worrying.
Of course, these data are only based on research, and there is no evidence that our current solar radiation is seriously lacking. If this conclusion is true, then it must be paid attention to. This is equivalent to what we call the relationship between sunspots and small glaciers. There is no specific evidence to indicate that this situation really occurs, so we still focus on the preliminary conclusions of the research.
At the same time, there is speculation in the scientific community that the increase in volcanic activity, the ejection of debris into the atmosphere by volcanic activity, or the formation of clouds has cast a shadow on the Earth, which may trigger The earth has entered a state of "extreme cold". At the same time, some people say that the earth will also enter the Little Ice Age in the future. Therefore, it is impossible to determine whether there is such a thing. This can only be regarded as a warning.
In fact, compared to today’s earth environment, we think it may be beneficial for the earth to enter the Little Ice Age. Of course, uniform cooling is needed here, because the temperature of our earth is already 1 higher than that of industrialization. Above the temperature, if it continues, our earth may become a "fireball", and small glaciers may be able to alleviate the global warming problem caused by humans.
In this way, the temperature of the earth will not be so high, so a more comfortable earth ecology will be better. Of course, if an extreme small glacier appears, then we will have a new problem. The extreme cold we face will also bring natural disasters, so everything needs to be balanced, otherwise it will not be good for life on earth. .
Now our earth is continuing to heat up. Everyone must recognize this fact. Moreover, the World Meteorological Organization predicts that 2020 may become the hottest year in history, so the continued warming is still developing. , we can only expect everyone to be highly vigilant at all times. If scientific researchers are accurate, then an exceptional weather phenomenon may reappear, and it will also have an impact, and now global warming For development, we also need to work together to maintain the stability of ecological balance and reduce damage.
