The military-industrial scientific research system of the academic master.

Although the IPCC is not a very serious occasion, Zheng Guogang's sudden remarks do sound a bit outrageous.

So much so that the first reaction of most of the audience, even including the American delegation, was to laugh out loud.

It's not a mockery.

I just subconsciously felt that this Chinese man wanted to liven up the atmosphere and cool down this room that was already filled with gunpowder.

However, some more alert people have already noticed that the Chinese representative's expression and tone are serious, and he doesn't seem to be joking at all.

I'm afraid he has some big trick up his sleeve.

In such a somewhat weird atmosphere, Zheng Guogang did not seem to be panicked at all.

He didn't continue speaking until the laughter gradually subsided.

"As we all know, carbon dioxide is not the only culprit for the greenhouse effect and climate change. It just gets the most attention because its emissions are very high compared to other greenhouse gases."

"However, according to our detailed calculations and reviews in recent years, the United States has emitted a staggering more than 5 million tons of methane in the past five years!"

Having said that, in order to deepen the impression for the audience below, Zheng Guogang deliberately paused for a moment.

But it didn't stop for too long.

Before most people understood the concept of 10 billion tons of methane, they explained:

"Although this amount is only about a quarter of the carbon dioxide emissions of the United States, considering that the GWP value of methane is more than 5 times that of the latter, the contribution of these million tons of methane to the greenhouse effect is almost five times that of carbon dioxide. In other words, it is equivalent to the total carbon dioxide emissions of the world in one year!"

Gradually.

The American delegation couldn't laugh anymore.

This is not livening up the atmosphere.

This is to dig up our roots!

But Zheng Guogang's attack did not stop, but became more fierce:

Having said that, he didn't care about the audience's reactions, but slowly took out two forms from the folder in front of him.

One of them is a line graph. Because the distance is too far, even through the picture taken by the camera, it is difficult to see clearly what is on it.

But the second picture is a diagram of emission concentrations across the North American continent:

"Moreover, compared to carbon dioxide, which can be absorbed and converted by biological means, methane stays in the atmosphere for a longer time. If calculated over a 100-year period, its average GWP value will be more than 80 times that of carbon dioxide. The damage to the ecological balance of the earth and the future development of mankind is incalculable!"

"After calculating the emission sources, we found that the areas with excessive methane emissions in the United States are highly overlapped with the areas where the livestock industry is concentrated. This is because even-toed ungulates such as cattle and sheep that are raised in captivity rather than in the free-range state will produce a large amount of methane gas during digestion due to nutritional metabolic imbalance..."

"In addition to damaging the climate, excessive methane emissions will also form accumulated methane clouds over nearby areas. The extremely severe natural disasters and extreme weather in the Americas in recent years are also related to this. The United States must bear responsibility for this..."

"As for the specific analysis process, we have released a complete report, you can check it out for yourself..."

"..."

Zheng Guogang was very pleased with this speech.

Although he had just taken office as deputy director of the Meteorological Bureau, this was not the first time that the IPCC and the United Nations had held a meeting on the environment and climate.

In the past, we could only passively defend ourselves unilaterally, and faced groundless rumors and slander. It was impossible not to feel aggrieved.

Now that I finally have the opportunity to stand on the moral high ground and point fingers at others, I naturally want to get rid of the depression that has been pent up in my heart for a long time.

They are just short of pointing their finger at Americans and scolding them as the cancer cells of the earth.

However, the first reaction of the American delegation to this straight ball attack was quite confusing.

Most people didn't even react until Zheng Guogang finished speaking.

Apparently, they never even thought that there would be a day when they would be blamed by others.

As for rebuttal... there is no way to even talk about it.

This is like when you go on stage for your graduation thesis defense without any preparation beforehand, and naturally you can only nod in fear when facing the judges' questions.

However, you can just answer the questions without defending them, as long as you land safely.

If the Americans don't say something about this wave, it will become a big joke.

The Brazilian representative who came on stage first was dumbfounded.

I just came here to ask for money as usual, how did I suddenly become the center of the storm?

The Amazon rainforest is dying, I'm just saying it casually, don't take it seriously!

Stay away, don't let your blood splash on me.jpg

In short, after Zheng Guogang finished speaking, for about half a minute, no one in the entire conference hall expressed their opinions publicly, leaving only some barely detectable whispers...

Fortunately, after the initial chaos, the US delegation quickly organized a counterattack:

"We object! This is an unfounded accusation!"

The American representative who had just come on stage roared angrily.

In fact, it is normal that there will be a concentrated question and discussion session after the speech session.

But as introduced before, there is really not much difference between a meeting of an organization like the IPCC and a vegetable market, especially now that everyone wants to see how the United States and China will fight each other, so the host just stopped it slightly out of responsibility, and when he saw that it didn't work, he just followed along and watched.

Zheng Guogang could have continued speaking regardless of the objections from the audience, but the methane emissions issue itself was a trap set for the Americans, so he simply stopped and signaled the other party to speak first.

"One billion tons of methane. That's simply not realistic!"

The voice of the US representative continued to resound throughout the conference room:

"Let's not talk about how terrible the greenhouse effect of this level of methane can be... If it is really as the Chinese representative pointed out, then as long as a match is struck in the air, it is possible to cause a fire over the United States..."

"In addition, as far as we know, China has not yet launched any satellites with methane detection capabilities, nor has it opened its airspace to any country for meteorological detection research. So, may I ask the Chinese representative, how did you obtain the data in the report, and how do you prove its reliability?"

It should be said that this approach is reasonable and well-founded.

Although the principle that even-toed ungulates produce methane through fermentation during digestion is correct.

But 10 billion tons, and point-like emissions?

If you really do the math, you'll find that the numbers are just like talking in a dream.

This is almost equivalent to having natural gas wells all over the United States, spewing natural gas into the air at all times and in all places.

If there are really so many words, wouldn't it be nice to collect them and sell them for money?

Even if it cannot be collected, we should build an air duct and burn it like an oil field.

Therefore, after this rhetorical question, the momentum at the scene seemed to have shifted back to the American side.

However, Zheng Guogang still looked normal and even remembered to drink some water to moisten his throat.

Obviously came prepared:

"If that's the case, it's very strange..."

He deliberately used an exaggerated tone and picked up two more pages of paper from in front of him:

"It is true that my country has not launched a methane detection satellite, but all the analysis we conducted in the report is based on the data released by the U.S. Environmental Protection Agency itself. For example, the methane concentration over North America is obtained by using carbon dioxide, whose concentration is known, as a reference and inverting the common absorption band of carbon dioxide and methane in the infrared spectrum."

"In addition to North America, we also used the same method to invert methane concentrations in East Asia, West Asia, Western Europe and North Africa. The results were all within 15% of the measured or estimated values ​​in these regions, which is enough to prove the effectiveness of this algorithm itself..."

"Of course, these documents are also publicly available on the websites of relevant departments in our country. You can check them yourself..."

Having said this, Zheng Guogang raised his head again and looked sharply in the direction of the American delegation:

"If this calculation method only has such a huge deviation in North America, it can only mean that... there are serious problems with the original data on pollutant emissions released by the US!"

!!!

In an instant, the whole place was in an uproar.

Even some national representatives who had originally had no interest in this kind of oral gymnastics became interested.

Although everyone has more or less suspected that the data released by the United States is inaccurate, this is the first time that the Chinese have brought the matter to the table.

More importantly, evidence was presented.

All the audience members turned their attention back to the delegates, ready to hear what arguments the United States would come up with to refute...
