In the future, extreme hot weather around the world will become more and more common. What is the basis?

In fact, when it comes to this issue, everyone should have thought of it, mainly because global warming is accelerating. "It's so hot!" This sentence may no longer be a complaint in the future, but a reality sweeping the world.

Everyone can feel the high temperature these days, such as myself. In fact, I don't turn on the air conditioner every summer and use the fan to cool down at night, but the high temperature this year is really unbearable. Really, as the title suggests, it is extremely high temperature. Now most parts of the country are undergoing the "baking" test. In Zhejiang, Sichuan, Henan and other places, the most serious cases of heatstroke-"heatstroke" have appeared. This disease was only taken seriously this year. It has never been heard of in previous years, and once it occurs, the highest mortality rate can reach 80%.

These days, you can often see cases of heatstroke death by brushing short videos: Xi' an, a 56-year-old migrant worker, fell on the road due to heatstroke and died in the early morning after being sent to the hospital; A 44-year-old female worker in Fujian fell with a temperature of 40.6℃ and died after being rescued. A 49-year-old man in Zhejiang suddenly fainted at work and suffered from liver failure. He was rescued for 3 1 hour and finally died.

These are all due to the extremely hot weather.

Not only our country, but also the whole world is suffering from high temperature. According to the World Meteorological Organization, in some places in Spain and France, the temperature is 10℃ higher than the average temperature in the same period last year. The French meteorological department said that this was the earliest high temperature day since 1947. On June 18, France ushered in the highest temperature, and more than 70 provinces issued high-temperature warnings, and many high-temperature records were broken.

And Britain, I don't know if you know it, but this country has always been famous for its cool weather. Even so, it failed to escape the extreme heat. On July 15, Britain entered a state of emergency due to high temperature. Three days later, the British meteorological department issued the first ever "extreme high temperature red warning", and the temperature in London exceeded the Sahara desert.

Hot weather also affects the central and southeastern United States. On June 2 1 day, the US Meteorological Administration issued a multi-site high temperature warning. It is reported that the daily high temperature record in the eastern and southern parts of the United States exceeds 100.

According to relevant data, the highest temperature of meteorological stations in more than 60 countries has reached or exceeded the historical extreme.

Regarding this round of hot weather, the World Meteorological Organization said that it will continue for some time, and also warned that extreme hot weather will become more and more common in the world in the future, which may last until 2060.

I really dare not think, does this mean that many people will die of heat every summer in the future?

Why is this happening? As we all know, the reason is global warming.

In fact, in 20 15, many countries realized the serious problem of the earth's temperature and reached the Paris Agreement, proposing to control the global average temperature rise within 2℃.

Because of climate warming, including extreme high temperature, countries all over the world have begun to pay attention to the environment. Not long ago, the World Meteorological Organization released a report, which mentioned that in the past year, four key climate indicators, such as greenhouse gas concentration, sea level rise, ocean heat and ocean acidification, all broke records.

Now many studies show that extreme weather events will become more frequent in the context of global warming. Of course, in everyone's consistent impression, the high temperature that breaks through our survival limit may still be far away, or it may take decades or hundreds of years. But just two years ago, Columbia University did a study, and the results showed that in many parts of the world, the high temperature in summer has approached or even reached the high temperature limit that human beings can tolerate.

Obviously, human activities lead to the continuous warming of the earth, so it is not surprising that there is extreme high temperature.

We knew in primary school that there is only one earth for human beings. Why extreme weather such as extreme heat keeps appearing may be a warning from the earth. It is time for mankind to unite and continue to live for the earth with practical actions. We don't know how hot it will be next summer, but it can be predicted that extreme high temperature will gradually become the normal state faced by all mankind. ...
