Why are there more and more extreme weather and how should we deal with it?

Do you still remember the rainstorm in Henan last July? Among them, the hourly rainfall in Zhengzhou, the capital of Henan Province, reached 201.9mm, exceeding the previous maximum rainfall in a single day. I really can't understand what I haven't experienced. That rainstorm triggered a catastrophic flood disaster, causing at least 302 deaths and 50 missing in Henan Province. 1, 453438+0,600 people were affected. It hurts to think about it. Human beings are really too fragile in front of nature. God is merciless, and has donated money and materials to Henan to send love and relief to compatriots in the disaster area. It is really warm.

In fact, since last year, extreme weather such as record-breaking rainstorms and cold waves have frequently visited countries around the world.

At the end of June, rare high temperatures swept through the northwestern United States and southwestern Canada, killing hundreds of people. Seattle, which is famous for its mild climate, unexpectedly reached 42 degrees Celsius, breaking the historical record.

In July, heavy rains in Germany and Belgium caused many rivers to burst their banks, and at least 229 people were killed by floods. A spokesman for the German Meteorological Administration said that no flood can be described as a "once-in-a-century flood", and this flood may be once in a thousand years. In addition, there is heavy rain in Maharashtra, India. In a town, the rainfall reached 594 mm within 24 hours, setting a new local daily rainfall record. In the end, 25 1 person died and 100 person was missing.

But sometimes it is really strange that some extreme weather will be accompanied by other extreme weather, such as floods in July and fires around the world.

In early July, the Republic of Sakha (the administrative region of the Russian Federation in northeast Siberia) claimed that there were more than 250 fires here. There are also sudden rainstorms in Shizuoka Prefecture and Kanagawa Prefecture in Japan, breaking the historical record.

At the end of July, the fire in Dixie, California was the eleventh largest fire in California history. At that time, as of August 12, Beijing time, the fire area reached 2045 square kilometers, almost equal to a Shenzhen city.

These are just the tip of the iceberg of extreme weather events.

What are these reasons? I think it has a lot to do with human beings, because it is a view close to * * *. Human activities have a great negative impact on the climate, and the causes of floods and fires are probably due to global warming.

In some reports, the relevant UN Climate Committee analyzed the relationship between global warming and extreme weather events, and the final conclusion was actually expected: the higher the temperature, the faster the global warming, and the greater the possibility of extreme weather. Anyway, I feel that the weather is getting hotter and hotter, and the hot time is getting longer and longer.

Talking about the relationship between climate warming and extreme weather, michael mann, a professor at Pennsylvania State University, said that climate change is reshaping the earth's temperature pattern. Nowadays, more and more greenhouse gases are released into the atmosphere by human beings, and the "energy" in the climate is gradually rising, and the excess "energy" will be manifested in the form of extremely high temperature weather.

A large number of data show that there is a close relationship between climate warming and extreme weather.

According to the data of the Potsdam Institute of Climate Research in Germany, every time the earth's atmosphere rises by 1 degree Celsius, it can absorb 7% of water vapor, and then precipitation will form. Measurement data confirmed that in some areas of Germany, there is not much light rain, but heavy rain often occurs.

The relevant meteorological organizations in the world have also reported that according to the current carbon emission level, the global average temperature will increase by 2℃ compared with the pre-industrial level in the decade from 2040 to 2049. At this temperature, extreme weather phenomena occur almost every 5- 10 years. Extreme weather and natural disasters may increase before mitigation of climate change achieves results.

Then we can't just give up on these extreme weather. We have to do something.

From a broad perspective, it is necessary to strengthen the ability of early warning and forecasting, disaster prevention and mitigation. With the development of science and technology, we can do many things. Such as the use of modern satellites, radar and other means, as well as the application of supercomputers. However, weather, meteorology, etc. is a very chaotic system, and small changes may cause unpredictable interference, which is also the difficulty we have to deal with.

Moreover, human beings should take the initiative to reduce carbon emissions, thus reducing the impact of human behavior on the climate. Experts from the China Meteorological Bureau said that the life span of greenhouse gases that have been discharged is still several hundred years, so we urgently need to control greenhouse gases as soon as possible.

You should have heard of the term carbon neutrality. China is striving to reach the peak of carbon dioxide emission in 2030 and achieve carbon neutrality in 2060. From the perspective of global carbon reduction, as of 2002 11,27 countries have promised to achieve carbon neutrality by the middle of 21century.

What should we do personally? Do your best.

For example, I seldom drive out. What age is it now? The traffic is so developed. Taking public transport is not only environmentally friendly and economical, but more importantly, it can reduce automobile exhaust emissions. I have been driving for five years, and now I seldom drive. I basically go to work by subway and bus. I also like riding and running, which exercises my body and contributes to the global climate.

I don't turn on the air conditioner much in summer. Although air conditioning is occasionally installed at home now, I still like to blow electric fans in many cases.

Also, when I go to the supermarket to buy food, I will not bring one, and try to reduce the use of plastic bags.

Food waste is also a big problem, and I, in order to eat, basically do CD-ROM movements, which is really a very environmentally friendly thing.

In fact, you can do a lot of basic necessities in your life. The key is for everyone to do it by himself. I would like to appeal to everyone here to cherish our lovely earth!
