Earth is the only planet known to mankind to survive. But in recent years, with the development of the earth by humans, the destruction and other factors have led to huge changes on the earth. In the past year, there have been many extreme weather phenomena in various countries in the world, such as: abnormal snowstorms on the east coast of the United States, extreme flooding in Germany, and Hurricane Ada in the United States.
All illustrate the fact that extreme climate events seem to be increasing and that the threat to humanity is growing. Moreover, in the context of global warming, all corners of the earth have been affected, up to the atmosphere, down to the ocean floor, there are footprints of climate impacts.
According to the 2021 Arctic Report released by the US NOAA, there is a big problem again, which really needs to be vigilant for human beings, what is the situation?
In 2021, "the Arctic is greener"!
As we all know, the Arctic is a very cold area, and it is indeed frozen all year round. However, satellite monitoring data shows that the Arctic is still in great change in 2021, and since the early 1980s, satellites have been observing changes in the productivity of tundra vegetation in the Arctic. This phenomenon is known as the "Arctic turning green".
In the monitoring of 2021, the strong greening trend throughout the Arctic region is still continuing, and 2021 is another summer peak period of greening.
Among them, in Canada, the "greening" of the Russian Far East is even greater, and the East and West Libya regions are the most obvious. This has led to the Arctic being "greener". Through data comparison, it was also found that 2021 was one of the five highest summer peaks recorded by long-term satellites, and this "green value" occurred in the past decade.
From the satellite imagery, we can also clearly see that indeed the changes in the Arctic Circle are huge, and almost the entire periphery of the Arctic Circle is covered with "green vegetation", whether inside the circle or outside the circle, there is a huge transformation. So, in 2021, "the Arctic is greener".
But this "greening" is not a good thing, according to the report, a large part of the trend of satellite greening is driven by the "shrubbing" of tundra. In many areas, the tundra shrubs become larger and denser. At the same time, it poses a huge threat to the permafrost of the Arctic and other regions, which is a huge change brought about by extreme climate changes and other factors.
If this trend continues, it will not be a good thing for the Arctic, and humanity really needs to be vigilant! This also shows that climate change is changing the Arctic. At the same time, the threat to humanity is accelerating. Some of the concerns scientists have in the Arctic, I'm sure many people have heard about it.
The Arctic has unearthed the bodies of prehistoric creatures, perhaps as a wake-up call
Under the influence of global warming, in addition to the "Arctic is greener" discovered in 2021, in fact, the Arctic excavated the corpses of prehistoric creatures, and the alarm bell for human beings is the most critical. After the Arctic heats up, the corpses of ancient creatures sealed in the permafrost continue to appear, which is indeed worrying.
For example, 80% of the female sub-adult wolf from the Permafrost of Canada, one of the most complete species found in the Permafrost of Russia, the "Woolly Rhinoceros", is found in the permafrost of Canada, 80% of which is well preserved and has intact internal organs, teeth and stomach contents.
This shows that human beings are letting these "frozen things" "see the light of day" from the permafrost. However, the excavation of prehistoric carcasses in the Arctic may also be just the beginning, and more creatures can be seen in the future, because the warming of the earth is still continuing.
According to the World Meteorological Organization's interim report on the "State of the Global Climate 2021", the average global temperature in 2021 (January to September) is about 1.09 degrees Celsius higher than in 1850-1900, while greenhouse gas emissions continue to grow in 2021.
What does this mean? The trend of global warming still exists, which is undeniable. Therefore, this will also promote the temperature change in the Arctic Circle again, and the extreme climate phenomena will probably be more, and the arctic wildfires we see, the Arctic greening and other phenomena may only be the "tip of the iceberg", or it may only be a preliminary stage.
So hurry up and change the climate, the weather alarm bell is not the first time to say, we can not wait any longer.
Earth Pandora's Box Opened? What about humans?
It is true that climate change should be taken seriously, and although we have only introduced changes in the Arctic Circle here, this does not mean that other regions of the earth have not changed. Our planet is a whole, and any region that does not achieve strict climate change may affect global changes. So, what about human beings? Only everyone is responsible, and once the earth's great changes continue to develop, more terrible things may be ahead.
Above we mentioned that the Arctic exhumed the corpses of prehistoric creatures, and there are more worrying questions, then the Pandora's box of the earth is really "completely open", what is more terrible?
That's what we call ancient bacteria, viruses, etc. French scientist Clavery once discovered a 30,000-year-old "giant virus" in Siberia that is 10 times larger than the standard 20-nanometer virus. It was subsequently revived in the laboratory and proved contagious despite being dormant for tens of thousands of years.
You say this is terrible isn't it? So, without releasing them, it seems that we can only change the climate. Moreover, this is only discovered, and there are still many unknown things that humans do not know. Therefore, we can't let the Earth Pandora's Box open, we should increase the change of climate, do not wait until the critical point of the climate "completely collapses", and then change the climate, at that time may really be late, time is gone, protect the earth well.
summary
Changes on the earth are a huge threat to human beings, whether it is the Arctic problem we are talking about, or the global problem, human beings need to find a way to deal with, although many countries around the world are also in response to the future changes of the earth, may put forward an ideal way, such as: Mars colonization, hoping to move humans to other celestial bodies, but from the current situation, human beings even the basic Mars landing is difficult, let alone inhabited on Mars.
Therefore, it is better to pay attention to the immediate problem, so that there may be more opportunities to see more celestial bodies, and even talk about migration, if the earth is not well protected, sooner or later there may be a "similar scene" when you go to Mars.
