Chapter 1162 Americans consume too much beef, which is an important cause of climate change...
Chang Haonan was not aware of the far-reaching impact of his paper at this time.
Because in the field of engineering, even the simplest and most straightforward uses require testing and verification, ranging from weeks to years.
And it is difficult for influence to spread beyond this field.
Therefore, if you want to make enough noise before the IPCC meeting, the focus should be on the second half of this paper.
That is the part related to artificial neural networks.
As we all know, if research in the computer field really wants speed, the development cycle and publication cycle can be extremely short.
The reason why websites that pre-publish papers like arXiv can survive and continue to grow is largely because the research iteration speed of these people is even faster than the review speed of regular paper journals.
If you follow the traditional process, it is likely that there will be a lot of disputes about originality.
The article by Chang Haonan and Lissel just provided a huge space for water papers to the majority of computer scientists who were engaged in emo during the Internet bubble.
Therefore, all major universities rushed to follow up. Higher-level scholars began to think about how to use similar ideas to expand new fields, while average-level researchers began to fill in the gaps.
In short, regardless of the specific contribution to the development of the industry, at least in terms of the number and popularity of papers, it is not weaker than some established research fields.
It is impossible for anyone to deny the correctness of this improved Levenberg-Marquardt method itself.
And this has already achieved Chang Haonan''s original goal...
…
In December 2004, the fourth IPCC assessment was officially launched.
In fact, in principle, the IPCC is closer to an academic conference between countries. It does not conduct any scientific research itself. Like an academic journal, it is not responsible for any adopted data itself, and only focuses on scientific evaluation methods, and in Analysis and suggestions are given under the premise of "assuming the data is true".
This is of course due to technical feasibility considerations. After all, the United Nations is not a real authority, and it is impossible to go to other people''s countries and conduct random investigations.
But it also shows that the conclusions given by the IPCC are not necessarily reliable.
But because it is backed by two platforms, the World Meteorological Organization and the United Nations Environment Program, and everyone still has to eat from the same horse spoon, they still tend to agree with its authority.
But when it comes to the evaluation process, the scene is actually not much different from a quarrel in the vegetable market.
And this year, due to a well-known reason, there was more of a smell of gunpowder from the beginning.
Since the number of countries participating in the IPCC assessment is not large, they can only learn from but cannot copy the order of speeches at the UN General Assembly. Therefore, in the past, just the matter of who came first and who came last was enough to discuss for a period of time.
But this time, when the U.S. representative proposed alphabetical ordering by country, no one raised any objection.
Even the Russian representative did not make any statement such as "The initials of your United States is clearly U."
Because under this arrangement, the United States will be next to China.
And everyone wants to see what kind of colorful sparks the two sides will ignite...
As a rule, Brazil is the first to speak, regardless of the order.
As representatives of South American countries, their core focus is naturally on the changes in tropical rainforests.
"In the past five years, due to extreme climate, deforestation, and natural disasters, the area of ??the Amazon rainforest has shrunk by approximately 13,000 square kilometers... I would like to remind everyone that the Amazon rainforest occupies half of the world''s rainforest area. , and one-fifth of the world''s total forest area, with irreplaceable ecological and climate value..."
"Previously, according to meteorological research, in 2005 and 2006, the American continent will suffer from a severe drought that has not been seen in a century. The entire region is already on the edge of desertification. Once the critical point is exceeded, the rainforest will irreversibly begin to die, and then the It will have a catastrophic impact on the global climate and even destroy the entire world..."
“…”
The Brazilian representative started off with an obviously alarmist content.
It’s okay to deceive the brainless so-called “climate activists” with these arguments, but whoever is here who is not a thousand-year-old fox cannot be deceived by these rhetorics that have long been used to hearing them.
The Amazon rainforest is indeed very important, but few people have mentioned that while the forest area is decreasing, it will also expand spontaneously. The annual net area reduction cannot reach the equilibrium critical point at all. As few people have mentioned, while "one species is destroyed on average every hour", new species are also appearing at about the same rate.
What everyone really cares about is whether there is any hidden purpose behind this passage...
"Let me tell you, Lao Ding, their statement clearly relied on the disaster data released by the US Environmental Protection Agency some time ago... Could it be that they want to cooperate with Lao Ding and target us?"
Zheng Guogang, deputy director of the China Meteorological Administration who was accompanying him, approached Ding Zhongli''s ear and asked in a low voice.
The latter lowered his head and thought for a moment, but still shook his head:
"Judging from past experience, most third world countries are on the same front as us in the IPCC, but South America is greatly influenced by the United States after all, and the representatives speaking on the stage may not really represent Brazil. People themselves, so I really can’t say…”
However, just when people here were already a little worried, the Brazilian guy on the stage suddenly changed the subject:
"The Amazon rainforest is a precious asset to all mankind, and rainforest protection is by no means a task for South American countries alone, but should be a joint responsibility of the international community..."
At this moment, everyone in the Chinese delegation breathed a sigh of relief—
The other party obviously did not have any political purpose, but simply used this as an excuse to ask for money.
Sure enough, the Brazilian representative quickly came up with the idea, hoping that the World Bank and developed countries could provide the country with corresponding quotas of environmental protection funds based on the proportion of tropical rainforest area...
Although this routine seems a bit crude, in the context of environmental protection, it is really impossible to be completely rejected.
After all, asking for money is already quite simple in the IPCC.
And some countries hope to use the banner of environmental protection to achieve even more unspeakable goals...
Just like the American representative who came to power later.
Just as everyone expected from the beginning.
After reviewing the global climate change data of the past five years as usual, he directly pointed the finger at China based on the speech made by the Brazilian representative:
"In the past five years, behind China''s rapid economic development are rapidly deteriorating environmental problems. Calculated in terms of total pollutant emissions, China has become the world''s largest polluter..."
"We have noticed that in order to further improve its economic growth data on paper, China has begun to develop the grassland area in the northeastern part of its territory. This will likely lead to severe soil erosion and desertification, and will have a huge impact on the global climate balance. In addition to the damage caused to the Amazon rainforest, here are satellite photos taken last year and this year. It can be clearly seen that the total area of ??vegetation has been significantly reduced..."
"China is the worst in terms of the bad results caused by its destruction of the environment. Countries around the world should work together to stop such destructive behavior..."
“…”
The U.S. representative clearly had a premeditated plan. Not only did he present quite detailed survey data, but he also spent almost one-third of his speech criticizing China''s development behavior in eastern Mongolia. His intentions were obvious.
In the past, the Chinese delegation''s strategy was basically to defend and refute the accusations made by the other party point by point.
Although it is organized, no matter how reasonable your explanation is, you will always be at a disadvantage in terms of momentum.
But this time, Zheng Guogang, who was about to speak, showed no psychological fluctuations.
I even wanted to laugh a little bit.
After the American representative left, he strode onto the stage almost impatiently.
Of course, as a decent person, it is impossible to start with a scolding attitude.
Instead, like the previous two, I first reported on the basic environment and climate conditions of the country and Northeast Asia.
After completing all the routine content, he slowly turned around and faced the US delegation who still didn''t know what was about to happen.
“Here, I would like to remind everyone that our country’s development in eastern Mongolia Province is itself part of a large environmental protection plan. These are aerial photos of the same place and location before and after development, which are much more detailed than satellite images. , it is enough to see that these lands were already in a state of desertification, but it is our development behavior that has improved the overall vegetation level..."
“…”
The previous part seems to be no different from the previous explanation.
But immediately after, Zheng Guogang suddenly changed his tone:
"On the contrary, we have sufficient evidence to prove that a large part of the causes of climate change and natural disasters just mentioned by the Brazilian representative are that Americans consume too much beef..."
