The Arctic is now 38 degrees hot! After large-scale methane release, will the earth turn into a fireball like Venus?

Since industrialization, under human activities, 75%of the earth’s land and 66%of the marine ecosystem have been changed, but now it is still intensifying, under these changing ecological environments Now, there are more and more problems appearing on the earth. Problems such as high temperature, drought, heavy rainfall, and strong storms are all”one by one,” and more extreme climate phenomena have also erupted in 2020.

So combining the influence of these climate factors, the earth’s ecological environment has now entered a worse stage, and perhaps only humans can work together to change all this.

Of course we have said before that this is not a personal problem, but a global human problem, so we can’t turn it off. Let’s take a look at some of the more typical climate phenomena, and NASA also announced climate-related issues again in July, and large-scale methane is being released.

The release of”methane” under the satellite lens is clearly visible

According to the new news from NASA in July, in The monitoring of more than 3.6 million lakes in the Arctic found that a large number of lakes have become abnormal, and sediments are being captured by palaebacteria microorganisms Decomposition, at the same time they release a lot of methane gas, which is accelerating the impact on global warming, because methane is the second largest greenhouse gas on earth, and methane has a heat absorption capacity 30 times stronger than carbon dioxide, so this will also be indirect Accelerated the high temperature pattern in the Arctic.

According to Alaska University scientist Melanie Engram said that this performance is very obvious no matter what the season. When methane emerges from the bottom of the lake, the bubble column acts as an”insulator”, slowing the growth of ice near the bubble column.

Now when part of the”methane column” is not released to the surface, the bubble column becomes larger and larger, and the entire number becomes more and more. Scientists have discovered as many as 5,143 lakes that emit methane in the estimated 134,000 lakes in Alaska alone.

So human With regard to climate change, the large-scale release of Arctic methane has already had a clear impact. This is the most important methane release point for global methane into the atmosphere except for carbon dioxide. The Arctic region will accelerate the global climate change Out of change.

Although this is an Arctic lake studied, the changes in some Arctic wetlands and permafrost also release methane at the same time, so the Arctic is basically the main area where methane exists, and now humans Its release is being accelerated. This is the large-scale release of”methane” under the lens.

38°C high temperature in the Arctic

It is true that extreme high temperature in the Arctic is very rare, and in the first half of 2020, it is not the first time that the Arctic has experienced 30°C The above high temperature phenomenon, and this 38 degree high temperature directly refreshed the limit value of the Arctic. As you can imagine, the Arctic is an important ice area on the earth. Generally speaking, as long as the temperature is above 0 degrees, the ice will melt, but 38 degrees appears in the Arctic area, which is an additional 38 minutes of high temperature. , Will cause the melting of hundreds of millions of tons of ice in the entire Arctic region.

So if In the future, such a situation will occur frequently, then the situation that scientists say that the Arctic is”no ice in summer” will become a trend, and here we also say that the reason for this situation in the Arctic next year is mainly because of the”abnormal high pressure” in the Arctic region. , Leading to the emergence of heating patterns in large areas of the Arctic, including the large Arctic regions where Russia is located, so this is the impact of climate change.

Of course we I also said that this is a rare temperature situation in the Arctic, and it is not normalized. We can only expect that this kind of heat wave will affect the Arctic in the future. Otherwise, the”coolant” that maintains the earth will no longer exist, and the future of the earth will It’s hard to guess.

What will the earth be like in the future?

If this trend of climate change does not decrease, then in the future the earth may really become a”fireball”. When we talk about”fireball”, we may think of a person, that is, one of the major predictions of Hawking is that”If global warming continues to intensify, humanity will not be able to survive on the earth.”

and follow With the intensification of global warming, Hawking believes that the earth will be like Venus, the surface temperature will be as high as 460°C, and humans will not be able to survive, so Hawking said that the future of the earth is relatively more severe.

These are based on the continuous increase of carbon dioxide emissions, and the temperature of the earth will gradually increase like Venus, and eventually become a fireball. Although we don’t know whether this will actually happen, there is a fact that we need to know that carbon dioxide emissions are indeed increasing today, so Hawking’s prediction may be true and may need to be confirmed.

Natural Science magazine also released a statement in July that human emissions of greenhouse gases (carbon dioxide) are expected to be 2025, which is likely to be higher than the warmest period in the past 3.3 million years .

So comprehensive In terms of circumstances, humans are indeed developing the Earth as”prescribed” by Hawking’s prediction. If the earth really becomes a fireball, then it really cannot survive. Many people may say that moving to other planets to continue human civilization , But now we have not found any habitable planet, this is the most critical. Therefore, the protection of the earth should be the first priority for everyone today, and we cannot continue to make mistakes.
