Chapter 1163 A turn of attack!
Although the IPCC is not a very serious occasion, Zheng Guogang's sudden statement does sound a bit violent.
So much so that the first reaction of most of the audience, even the American delegation, was to laugh out loud.
It's not a mockery.
I just subconsciously felt that this Chinese person wanted to liven up the atmosphere and cool down the room that was already filled with the smell of gunpowder.
However, some more astute people have already noticed that the expression and tone of the Chinese representative are serious and do not look like they are joking at all.
I'm afraid he's holding back some big moves.
In such a strange atmosphere, Zheng Guogang showed no panic at all.
It wasn't until the laughter gradually subsided that he continued to speak.
"As we all know, carbon dioxide is not the only culprit that causes the greenhouse effect and climate change. It is only because its emissions are very high compared to other greenhouse gases that it has received the most attention."
"However, according to our detailed calculations and reviews in recent years, the United States has emitted a staggering more than 500 million tons of methane in the past five years!"
At this point, Zheng Guogang deliberately paused for a moment in order to impress the audience below.
But he didn't stop for too long.
Before most people could understand the concept of 1 billion tons of methane, he explained it first:
"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 twenty times that of the latter, the contribution of these 500 million tons of methane to the greenhouse effect is almost as much as that of carbon dioxide Five times, or to put it another way, it is equivalent to the total carbon dioxide emitted by the world in a year! ”
Gradually.
The American delegation couldn’t laugh anymore.
This is no way to enliven the atmosphere.
This is to dig out our roots!
But Zheng Guogang's attack did not stop, but became more fierce:
At this point, he didn't care about the reactions of the audience, and just took out two forms from the folder in front of him.
One of them is a line chart. Because the distance is too far, even through the picture captured by the camera, it is difficult to see clearly what is on it.
But the second picture can be seen at a glance. It is a schematic diagram of the emission concentration of the entire North American continent:
"Moreover, compared with carbon dioxide that can be absorbed and converted by biological means, methane stays in the atmosphere for a longer period of time. If calculated on a 100-year cycle, its average GWP value will be more than 80 times that of carbon dioxide, which is very important for the earth's ecology. The damage to balance and the future development of mankind is even more immeasurable!”
“After calculating the emission sources, we found that the areas with excessive methane concentration emissions in the United States are highly coincident with areas where the breeding industry is concentrated, because cattle and sheep and other artiodactyl animals that are raised in captivity rather than free-range will suffer from nutritional deficiencies. The metabolic balance is imbalanced and a large amount of methane gas is produced during the digestion process..."
“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 American continent in recent years are also related to this. The United States must take action for this. Take responsibility..."
"As for the specific analysis process, we have released a complete report, you can check it yourself..."
"..."
Zheng Guogang was so happy with this speech——
Although he has just assumed the post of deputy director of the Meteorological Bureau, this is not the first time that the IPCC and the United Nations have held meetings on environment and climate.
In the past, we could only defend ourselves unilaterally and passively, and we were faced with baseless rumors and slander. It was impossible not to feel aggrieved.
Now that I finally have the opportunity to point fingers at others from the moral high ground, I naturally want to clear away the long-standing depression in my heart.
Just point your nose and scold Americans as the cancer cells of the earth.
Faced with this through-ball attack, the U.S. delegation's first reaction was quite confusing.
Most people didn't even react until Zheng Guogang finished speaking.
Obviously, they didn't even think that they would be criticized by others one day.
As for rebuttal...it's impossible to talk about it.
It's like you go on stage for your graduation defense without any preparation in advance. Naturally, you can only obey the judges' questions.
However, you can just answer without defending, as long as you land safely.
If the Americans don't say something this time, they will make a big joke. The Brazilian representative who was the first to take the stage was even dumbfounded——
I just came here to ask for money as usual, why did I suddenly become the center of the storm?
The Amazon rainforest is dying. I'm just saying it casually, but I can't take it seriously!
Stay away, don't spill blood on me.jpg
In short, after Zheng Guogang finished speaking, for about half a minute, no one in the entire conference hall publicly expressed an opinion, only some unintelligible 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 taken the stage roared angrily.
In fact, logically speaking, 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 voices of the American representatives continued to ring through the conference room:
"Not to mention 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 to 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 really are 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 field.
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.
Obviously he came prepared:
"It would be strange if that were 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 material is obtained by inverting the concentration of the common absorption band between it and methane on 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. The effectiveness of 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...
