What NA0962 had been worrying about came up?

Lingu Glacier.

Gu Kaiwen was asking Professor Li Rongguo, and he vaguely felt that the consequences of the large-scale collapse of the ice cave in the Lingu Glacier were not simple, although global warming was no longer a simple matter.

In the face of Gu Kaiwen's inquiry, Li Rongguo did not answer immediately, he was thinking about how to answer.

As Gu Kaiwen guessed, although there is no exact data to support it now, with rich experience, Li Rongguo has already guessed some possible serious consequences.

Looking at Li Rongguo's silence, Gu Kaiwen took a breath of talk, he turned his head to Sun Fei and said, "Brother Sun, which professor is one of the top two glacier experts in our country?"

Before Sun Fei answered, Gu Kaiwen added, "From the current point of view, the situation of the Lingu Glacier is very complicated, and Professor Li, who is one of the best, should be too busy, and I am ready to invest a sum of money to invite more glacier experts to study the Lingu Glacier." ”

Li Rongguo frowned, he knew that this was Gu Kaiwen demonstrating, if he Li Rongguo wanted to hide the situation, Gu Kaiwen could invite more glacier experts to come over and uncover the answer.

In the face of Gu Kaiwen's strength, Li Rongguo smiled helplessly, he lowered his voice and said, "Mr. Gu, the matter of Lingu Glacier is a bit serious, I hope you know not to publicize it." ”

Before Gu Kaiwen answered, Li Rongguo added, "At present, there is a large-scale collapse of ice caves in the Lingu Glacier, in fact, I didn't lie just now, I really don't know what the serious consequences are, I can only infer according to experience." ”

"Then what is the result of Professor Li's inference?" Gu Kaiwen asked.

Li Rongguo fell silent again, this time Gu Kaiwen didn't urge him, anyway, the demonstration was also demonstrated, and Li Rongguo also relented, and now he was just thinking about how to organize the language.

Almost a minute later, Li Rongguo said in a low voice, "The problem of a large-scale collapsed ice cave in the Lingu Glacier is very serious!"

"Oh?" Gu Kaiwen asked cooperatively, "For example?"

"For example, we have preliminary measurements of the storage of carbon dioxide and methane beneath the Lingu glacier, which will accelerate the rate of global warming once they are released into the air. Li Rongguo explained.

"Mr. Gu, you should know that carbon dioxide and methane are greenhouse gases, right?" asked Li Rongguo jokingly.

Li Rongguo did not wait for Gu Kaiwen's response, and continued, "The worse situation is that methane accounts for the majority of the greenhouse gases buried under the Lingu Glacier, and in the greenhouse effect, methane's ability to absorb infrared rays is 26 times that of carbon dioxide, and the greenhouse effect is 22 times higher than that of carbon dioxide, and methane accounts for 15% of the total contribution of the global greenhouse effect." ”

Gu Kaiwen asked rhetorically, "If the greenhouse gases buried under the Lingu Glacier escape, to what extent will the change in global temperature change?"

"According to our preliminary investigations, the total amount of carbon dioxide buried under the Lingu Glacier is likely to reach more than 100 million tons, and the current annual global carbon dioxide emissions are about 5 billion tons, although it seems that the annual emissions of the Lingu Glacier are only 2%, but in fact this is already an astronomical amount of carbon dioxide, once emitted into the atmosphere, it will bring fatal consequences. Li Rongguo explained.

"In addition, the methane content is more than 200 million tons, and if 200 million tons of methane are emitted into the atmosphere, the projection that the global temperature in 2030 will rise by 1.5 degrees Celsius to 4.5 degrees Celsius compared to 2000 levels is likely to be met by 2025, according to the greenhouse effect of methane. Li Rongguo said with a sigh.

Gu Kaiwen could clearly understand every word the other party said, but all the words were connected together, and Gu Kaiwen didn't know what it meant.

Li Rongguo seems to be aware that Gu Kaiwen is not a researcher in this field, and he explains, "The consequences of temperature rise are very serious, first of all, the melting of the polar ice sheets, which will bring about sea level rise, which is about 20 centimeters to 140 centimeters according to the temperature rise forecast of 1.5 degrees Celsius to 4.5 degrees Celsius, and the impact of such sea level rise on coastal cities is very huge." ”

Gu Kaiwen's face darkened, if the sea level rose by 140 centimeters, his Novo Islands would bear the brunt, and the fifteen islands would be reduced by almost half.

"The rise in sea level brought about by the rise in global temperature will further affect the change of ocean currents, which will affect the marine ecology, and the change of marine ecology will affect the marine fishery, which will affect human access to marine resources, which is also a big problem," Li Rongguo explained.

Li Rongguo continued, "On land, higher temperatures will bring huge trouble. Mr. Gu, you graduated from the College of Agriculture, you should know, right?"

Gu Kaiwen nodded affirmatively, "Higher temperatures will bring greater tests to plants, for example, the acceleration of soil water evaporation will bring higher agricultural production costs." If it is a plant in nature, it will be at risk of dying if it does not have access to enough water. ”

Li Rongguo continued, "That's right! Once the plants in nature die on a large scale, it will cause the death of herbivores and some insects that rely on plants.

Gu Kaiwen shook his head, "Yes, the bottom layer of the ecological chain has collapsed, and it is impossible for the upper layer to survive, which means that the ecological chain in the area where the plants die has collapsed." ”

"Can Mr. Gu imagine that kind of situation?" asked Li Rongguo.

Gu Kaiwen nodded with a serious face, "That's really a bad situation!"

"No, no, no, Mr. Gu, that's not the worst situation, in fact, there are even worse situations. Li Rongguo responded.

"What's worse?" Gu Kaiwen was stunned for a moment, and then suddenly realized, "Pull a hair and move the whole body!"

The ecological environment of the whole earth is a huge ecological chain, and temperature is an important part of it, and when there is a problem in this ring, which causes a huge impact, it will not stop, but will intensify. Li Rongguo sighed.

"When plants die on a large scale, the ability to convert carbon dioxide is weakened, the amount of carbon dioxide accumulation will be further increased, and when the amount of carbon dioxide is further increased, the greenhouse effect will be more serious, so that the temperature will be higher, and then it will officially enter the vicious circle stage. Li Rongguo said with affection.

"Even the nausea cycle is not the worst situation!" Li Rongguo gritted his teeth and added, "When the temperature reaches a certain threshold, there will be more conditions similar to those of the Lingu Glacier, such as large amounts of carbon dioxide and methane in the swamps and oceans. ”

"Isn't that worse?" Sun Fei interjected.

Gu Kaiwen's expression was solemn, "I think it's more appropriate to add fuel to the fire." ”

"Yes, it is indeed adding fuel to the fire, and once such a situation occurs, it will be equivalent to adding fuel to the fire, and the trend of rising global temperatures will be difficult to contain. Li Rongguo's face was helpless.

Sun Fei finally heard a clue, and he looked at Li Rongguo dumbfounded, "Professor Li, are you kidding?"
