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

Faced with such a sudden turn, the American representative, who had been very confident just now, was shocked on the spot.

In fact, about ten minutes ago, he had doubted whether the Chinese had any backup plan.

After all, the claim of emitting 10 billion tons of methane is too outrageous. Even if it is just nonsense, it should be a relatively realistic number.

But after all, there was no preparation beforehand, and they could only launch a counterattack against the only obvious loophole left by the Chinese.

Unexpectedly, this apparent loophole turned out to be a dead end.

Now he either has to admit that there is something wrong with his first rebuttal, or he has to admit that there is something wrong with the carbon dioxide emissions data he released...

Being caught between a rock and a hard place is the norm.

"Cunning Chinese!"

His anger was burning in his heart, but he had to maintain a polite attitude on the surface.

The most basic logic of a fight is that whoever breaks the defense first loses.

Looking at the American representative in front of him with a changeable expression, Zheng Guogang felt relieved!

When surrounding an army, there must be a gap. This is the true wisdom left by our ancestors.

Learn, kid!

He picked up the cup, drank a sip of water leisurely, then lowered his head to tidy up the speech in his hand.

There are about 30% of content left, half of which are contingency plans for various situations, but there is no rush to continue firing.

Today's meeting only represents the official launch of the fourth assessment. There will not be any result anyway, so even if there is a big argument, it is just oral gymnastics.

What really matters is the last 15%.

That is China's brand-new initiative to address climate change.

Finally, after Zheng Guogang deliberately delayed for about a minute, the US side finally came up with a new excuse:

"The algorithm used by China to invert methane concentration using the signal intensity of infrared spectra and carbon dioxide as a reference has not been fully verified, and is not a methane concentration measurement method recognized by the IPCC and my country's Environmental Protection Agency. Therefore, we cannot recognize the reliability of any data and conclusions related to it..."

"..."

Before he finished speaking, the whole conference room was already filled with a cheerful atmosphere.

This time, it was merciless ridicule——

Although most people have not read the public report released by China in detail, it is even less likely that they know what this "improved Levenberg-Marquardt method" is all about.

But since the Chinese dare to release the entire calculation and analysis process openly, it means that there is probably no fatal error.

Otherwise, why doesn’t the United States dare to show everyone the raw satellite data related to carbon dioxide remote sensing?

As for the American population’s “disagreement with the reliability of the data and conclusions”…

In the eyes of the old hands in the meeting, unless you can give reasons for disagreeing, this statement is more like rolling around than a rebuttal.

The nature is similar to the "bounce back" or "I'll tell the teacher" response of primary school students after they fail in an argument.

Incompetent and furious belong to yes.

Of course, the US delegation also knew that such a counterattack was futile, but they could not think of a better way at the moment, so they could only save face and pretend nothing had happened.

Anyway, judging by the time, it’s almost time for China.

Besides, they have already given up the fight, so it’s impossible for the other side to perform a stand-up comedy, right?

You don’t say, it really works.

Zheng Guogang hasn't had enough fun yet, so he doesn't care about you.

Keep firing:

"In fact, as the US representative said, the annual emission of 10 billion tons of methane is indeed beyond common sense. Therefore, we tried to reverse the entire inversion process, that is, to use the methane content in the atmosphere announced by the US as a reference to calculate the total amount of carbon dioxide emitted, so that we can get a number that is more in line with realistic factors."

In order to emphasize this, he deliberately slowed down his speech:

"According to our calculations, the United States emitted about 2003 billion tons of carbon dioxide in 95, not the 69 billion tons they announced, accounting for more than 4% of the world's total emissions last year..."

This time, it’s not just the American delegation that can’t laugh.

Any rational person would know that the 10 billion tons of methane figure just now is false after a little analysis.

But 95 billion tons of carbon dioxide doesn't sound outrageous at all.

On the other hand, everyone actually expected Americans to conceal the numbers.

But no one thought that these old Bs could conceal so much...

You know, although everyone has their own ideas about emission reduction, for most countries, especially those in Europe and America, the consequences of climate warming are still real.

The extra 30 billion tons per year must be included in the carbon debt of mankind according to the Framework Convention on Climate Change.

At that time, it will undoubtedly further add to the already heavy task of emission reduction.

In this situation, Zheng Guogang then added fuel to the fire:

"This figure is equivalent to an average of 30.8 tons of carbon dioxide emissions per American, even exceeding Saudi Arabia, which currently ranks first on the public list, and is 6.3 times the world average..."

"In fact, this summer alone, the Taylor forest fire in Alaska released about 5000 million tons of carbon dioxide, which is equivalent to the total net carbon dioxide absorption of this forest in the past half century..."

"..."

Looking at the increasingly gloomy faces of the American and European representatives, Zheng Guogang knew that the time was almost right.

In the final analysis, whether it is Europe or the United States, at least for now, there is more cooperation than conflict.

It's impossible to really ruin the situation completely.

Therefore, he changed the subject at the right time and his tone became gentler:

"We are saying this not to really blame anyone, but just to refute the unfounded accusations made by the United States."

"my country is sitting in the IPCC meeting to solve the climate problem, not to sabotage it..."

After several rounds of full-force attacks that put the opponent out of action, Zheng Guogang seized the moral high ground with two sentences and continued:

“So I’m making an initiative here.”

"The impact of human activities on climate change has only become apparent since the Industrial Revolution. Therefore, when we discuss the emission reduction responsibilities of various countries, we cannot only consider the current situation or the past ten or twenty years, but should start from the mid-eighteenth century."

"Some countries have enjoyed sufficient development dividends in advance and have already caused damage to the environment. For fairness, these countries should bear this part of the responsibility themselves. Only after these historical issues are calculated in detail, the remaining emission reduction responsibilities should be distributed among countries around the world."

"At the same time, out of humanitarian principles and the most basic human rights considerations, people of all countries, regardless of race, skin color, or gender, should have equal emission rights. That is, the carbon emission cap that each country should obtain should be determined according to its population size... On this basis, China, as a responsible major country, voluntarily reduces emissions by an additional 10% to set an example for other countries in the world..."

"..."

This series of suggestions is the core strategy of the Chinese delegation this time.

In the past, others always set the questions and we did them.

Now, it is our turn to set questions for others to do...
