Chapter 1163: A Change of Offensive!

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

So much so that most of the audience, including the US delegation, laughed out loud as a first reaction.

It was not a mockery.

It was just that they subconsciously thought that this Chinese person wanted to liven up the atmosphere and cool down the room that was already filled with gunpowder.

However, some more alert people have already seen that the Chinese representative's expression and tone are serious, and he doesn't look like he is joking at all.

I'm afraid he has some big tricks in mind.

In such a weird atmosphere, Zheng Guogang did not panic at all.

He continued to speak until the laughter gradually subsided.

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

"However, according to our detailed calculations and reviews in recent years, the United States has emitted an astonishing 500 million tons of methane in the past five years!"

At this point, in order to make the audience more impressed, Zheng Guogang deliberately paused for a moment.

But he didn't stop for too long.

Before most people figured out the concept of 1 billion tons of methane, he explained:

"Although this amount is only about a quarter of the United States' carbon dioxide emissions, considering that the GWP value of methane is more than 20 times that of the latter, the contribution of these 500 million tons of methane to the greenhouse effect is almost five times that of carbon dioxide, or in other words, it is equivalent to the total carbon dioxide emitted by the world in one year!"

Gradually.

The US delegation couldn't laugh anymore.

This is not to liven up the atmosphere.

This is to dig up our roots!

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

At this point, he did not care about the audience's reaction, but slowly took out two tables from the folder in front of him.

One of them was a line graph. Because the distance was too far, even through the camera, it was not clear what was on it.

But the second one was a schematic diagram of the emission concentration of the entire North American continent:

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

"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 breeding industry is concentrated, because even-toed ungulates such as cattle and sheep that are kept in captivity rather than in a free-range state will be due to The imbalance of nutritional metabolism produces a large amount of methane gas during digestion..."

"In addition to destroying 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, and you can check it yourself..."

"..."

This speech made Zheng Guogang feel very happy--

Although he has just taken office as the deputy director of the Meteorological Bureau, it is not the first time that the IPCC and the United Nations have held meetings on the environment and climate.

In the past, we could only passively defend unilaterally, and we were faced with unfounded rumors and slander. It is impossible to say that we don’t feel aggrieved.

Now we finally have the opportunity to stand on the moral high ground and point fingers at others, so we naturally have to sweep away the long-accumulated anger in our hearts.

It’s just a matter of pointing fingers and scolding Americans as cancer cells of the earth.

Faced with this straight ball attack, the first reaction of the US delegation was quite confusing.

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

Obviously, they didn't even think that they would be accused by others one day.

As for rebuttal... there was no way to talk about it.

It's like you go on stage for graduation defense, you didn't prepare in advance, and you can only nod in the face of the judges' questions.

However, you can only answer the defense without defending, as long as you land safely.

If the Americans don't say something this time, it will be a big joke.

The Brazilian representative who came on stage first was dumbfounded-

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

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

Stay away, don't bleed on me.jpg

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

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

"We object! This is an unfounded accusation!"

The US representative who just came 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 mentioned before, there is really not much difference between a meeting of an organization like the IPCC and a wet market. Especially now everyone wants to see how the United States and China will fight, so the host just stopped it a little out of responsibility. , and after seeing that it didn’t work, he followed suit.

Zheng Guogang could actually continue speaking regardless of the objections from below, but the methane emission issue itself was digging a hole for the Americans, so he simply stopped and motioned for the other party to speak first.

"One billion tons of methane is simply unrealistic!"

The voice of the American representative continued to echo in the conference room:

"Let's not talk about the terrible greenhouse effect that methane of this magnitude can cause... If it is true as the Chinese representative pointed out, then as long as a match is struck in the air, it may cause a fire over the United States... …”

"In addition, as far as we know, China has not launched any satellite with methane detection function so far, nor has it opened its airspace to any country for meteorological detection research. So, please ask the representatives of China, how did you obtain the report? How can we prove its reliability?”

It should be said that this angle of entry is reasonable and well-founded——

Although the principle of fermentation to generate methane during the digestion process of artiodactyls is correct.

But 1 billion tons, and it’s still a point emission?

If you really put pen to paper and do the math, you will know that the numbers are indeed just talking in your sleep.

This is almost equivalent to having natural gas wells all over the United States, spewing natural gas into the air anytime and anywhere.

If there are really that many, wouldn't it be good to collect them and sell them for money?

Even if it can't be collected, it should be burned through a bleed pipe like in the oil fields.

Therefore, after this rhetorical question, the momentum at the scene seemed to shift toward the United States again.

However, Zheng Guogang still looked as normal, and he even didn't forget to drink some water to moisten his throat.

Apparently he came prepared:

"It would be strange if that was the case..."

He deliberately used an exaggerated tone, and at the same time picked up two other pages of paper in front of him:

"It is true that our country has not launched a methane detection satellite, but all the analyzes we conducted in the report are based on data released by the U.S. Environmental Protection Agency. For example, the methane concentration over North America is based on carbon dioxide with a known concentration. The reference object is obtained by inverting the concentration of the common absorption band between it 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 within 15% of the measured values ​​or estimated values ​​in these regions themselves, which is enough to prove this algorithm. Effectiveness in itself…”

"Of course, these documents are also made public on the websites of relevant departments of our country, and you can check them by yourself..."

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

"If this calculation method shows such a huge deviation only in North America, it can only mean that... there are serious problems with the original pollutant emission data released by the United States!"

! ! !

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

Even some national representatives who had no interest in this type of oral gymnastics became energetic now.

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 people have brought the matter to the table.

More importantly, evidence was produced.

The attention of all the audience turned to the representatives' seats again, ready to hear what kind of rhetoric the United States would come up with to refute...
