Global warming is inevitable. If the global temperature rises in 20 years, will the extreme climate increase greatly?

We may be able to do something now, but in the end we can't do anything. China, the United States, Europe and Russia are all too busy confronting each other to take care of the United Nations. What other countries say is useless. We may cooperate and wait for the alien invasion.

It's possible. These countries really have the ability to influence global decision-making. To repeat the beginning, we may be able to do something now, but in the end, we can't do anything. One more thing, calm down. To be honest, your reply is reasonable, so in the end I will say that there is nothing we can do.

The most important foundation of cooperation is two words. Fairness does not need absolute fairness, but at least it is relative fairness. But fairness is maintained by strength, and the five permanent members themselves have also used the topic of carbon emissions, as we can see.

The greater the power, the cheaper the country is, so the power to maintain fairness does not exist. Why did your majesty rebel? JPG, my answer.

I'm just saying I can't cooperate As for whether you emphasize active confrontation or passive confrontation, the average person in history is still the average person now, and so on, this is not my topic.

The confrontation has always been there. If there is no confrontation between China and the United States, there will be confrontation between the United States and Japan. The United States and Russia have nothing to do with the country. As for what efforts our country has made, it has nothing to do with cooperation, but the more we make unilateral efforts, the more qualified we are to point at other countries' noses in the future and say, I think occupying the right to speak in the future is the best incentive to stimulate countries to make changes. ?

Sweden introduced environmental protection girls from Europe. Sweden's per capita carbon emission is 4.54, and Europe will definitely not introduce environmental protection girls from Germany. The United States can't manage the climate, so it will withdraw from the Paris climate agreement before. Can China snatch more discourse power in the future?

Look, I'm still young anyway ~

I think the concept of environmental protection is very good. Otherwise, China's heavily subsidized photovoltaic industry will lose a lot. A few years ago, university teachers

I also said that photovoltaics were opened by foreigners, and later they all quit. We were cheated. From now on, we can only say that a blessing in disguise is a blessing in disguise.

How do you know it's not a blessing?

According to the latest report of IPCC, from 1850 to 1900, greenhouse gas emissions caused by human activities increased by about 1. 1℃.

Temperature, it is estimated that the global average temperature will reach or exceed 65438 0.5℃ in the next 20 years.

In this regard, the "Global Climate 2020" released by the World Meteorological Organization in April this year shows that in 2020, the global average temperature

It is 1.2℃ higher than the pre-industrial level (1850 ~ 1900 average), which is the warmest three years since the complete meteorological observation record.

One.

The direct consequences of global temperature rise include: sea level rise, melting and shrinking of mountain glaciers, and shrinking of Arctic sea ice.

After the 1990s, ocean warming accelerated obviously, which led to the accelerated rise of global average sea level. A set of comparative data shows: 1990.

The increase rate of global ocean heat content in 2020 is 5.6 times that of 1958 ~ 1989. The average rise of global sea level

The speed has increased from1901~ 65438+1.4 mm/year in 0990 to 1.3 mm/year in 2020.

According to the latest IPCC report, even if carbon neutrality can be achieved in 2050, by the end of this century, the sea level will still be 62 cm higher than that between 1995 and 20 14 years.

The rising trend of sea level is irreversible.

Sea level rise has brought challenges to some low-lying coastal cities. A few days ago, due to the rising sea level, the foundation was seriously occupied.

Eclipse, a house on the edge of a cliff in Buenos Aires, Argentina, fell into the sea.

At the same time, the global mountain glaciers are also in a state of melting and shrinking. According to the data released by a Swiss research institute on July 19,

From 2006 to 20 16, due to the melting of glaciers, the Alps in Switzerland increased by 180 glacial lakes.

At the press conference of China Meteorological Bureau in August, Jia Xiaolong, deputy director of the National Climate Center, introduced the extreme weather and climate in the world this summer.

Frequent occurrence is a direct manifestation of global atmospheric circulation anomalies. In addition to specific reasons, climate warming has aggravated the instability of the climate system, which is

Important climatic background leading to frequent occurrence of extreme weather and climate events.

Jia Xiaolong said that a large number of studies have confirmed that in the context of climate change, the warmer atmosphere can accommodate more water vapor before saturation.

Therefore, when the precipitation conditions are favorable, the risk of extremely strong precipitation is greatly increased. Influence of global warming on this year's heavy precipitation process

The contribution rate needs further study, but it is generally recognized that global warming increases the probability of extreme precipitation.

According to Reuters, a paper published in Geophysical Communication on June 30 pointed out that with the emission of greenhouse gases,

By the end of this century, the frequency of storms producing heavy rain in Europe may increase by 14 times.

In addition, climate change has also changed the living environment of other species except human beings.

For example, melting glaciers will not only accelerate sea level rise, but also threaten the survival of polar animals. Previous studies have shown that the world

At the end of this century, polar bears and emperor penguins will be extinct.

The book "The Age of Species Extinction" outlines such a picture: when the climate is warming, some animals and plants have to migrate to adapt to the change, while the world transformed by human beings is full of broken forests, countless cities and roads extending in all directions, and the spread and migration of organisms are hindered.

Disappearing animals and plants, from hundreds to thousands, may eventually be millions, and the composition of the biosphere is constantly changing.

Change.

Based on the number and speed of species extinction on the earth, more and more scientists believe that the earth is welcoming the sixth mass extinction.

What will happen to mankind after more and more species are extinct? Paul Early Heezen, an ecologist at Stanford University, said, "Push other species.

In the process of extinction, human beings are also busy sawing off the branches on which they live. "Every year in September, 10 months, in our memory, it's just a fairy day in autumn. Well, it's also happy event with fragrant rice and strong grouting. In this way, September1October in 2020 is a bit special. Even if it rains for 45 days at low temperature, it will be a fruitful autumn.

This has been terminated.

According to the old people, they have never seen such an achievement. It should be once in 60 years.

A month ago, Zhengzhou, which is said to be a once-in-a-thousand-year rainstorm, officially reported that the grain harvest area exceeded 5 million mu.

Yesterday Suizhou was accompanied by a rainstorm, which took away more than 20 people.

I wonder how much the high temperature in the United States will affect the output of several major grain exporting countries this year.

I don't know what will happen to our land next. I dare not imagine, and I don't want to think about it.

The ostrich mentality may be the human nature of ordinary people. In recent years, we seem to have forgotten something on the road of developing economy and pursuing wealth and happiness. May the mountains and rivers be safe, and may the people be safe!
