Extreme weather is no longer a "extreme" incident

What the British Meteorological Agency scientist Professor Stephen Bell Chee did not expect that "you can see a high temperature record in the UK in his career" in his career. " In fact, from Europe to North America, the entire northern hemisphere has been attacked by abnormal high temperature this summer.

Researchers warn that extreme weather is not only a natural disaster, but to a large extent, it is human disaster. From many places in Europe more recorded faster than expected, to California California's more frequent mountain fires ... As the climate changes intensify, extreme high temperatures are likely to be raging frequently, and extreme weather is no longer a "extreme" incident.

Extreme weather is faster

After Cambridge University Botanical Garden recorded the highest temperature of the country's official record of 38.7 degrees Celsius in July 2019, "Nature · Communication" magazine has published a research warning that European heat waves are getting worse, and 40 degrees Celsius have abnormal high temperature weather in the UK. The possibility is rapidly increasing. With the continuous climate change caused by human activities, it is expected that there will be new high -temperature records in the UK in the next decades.

At noon on July 19, 2022, the thermometer of the Heathrow Airport in London was finger to 40.2 degrees Celsius, which greatly broke the highest temperature record 3 years ago.

Although the scientific community has continuously issued early warnings on extreme weather phenomena caused by climate change for decades, countries that are rarely installed in the UK in the UK, abnormal high temperatures still have more ecosystems, public health, transportation, infrastructure, school education, etc. It has seriously affected this area.

Scientists are worried that the increase in extreme weather incidents may be faster than expected. Korina Le Cry, a professor of climate change at Dongying Geely University in the United Kingdom, said in an interview with Xinhua News Agency that the Britain was very unusual, but "not surprising." She pointed out that climate change has led to an increase in extreme high temperature in the world, and Britain "definitely has no preparation for this extreme temperature", and the speed of climate change is faster than the adaptive actions of human society.

Extreme weather is no longer "extreme"

Not only in the UK, the northern hemisphere has ushered in big "baking" this summer. According to media reports, high temperature superimposed droughts have caused wildfires from Portugal to the Balkan Peninsula, causing hundreds of people to die; in the United States, high temperatures have led to tight power supply in Texas. Extreme high temperatures in some areas have melted high -voltage cables. Deformation; in Vancouver and other places in Canada, high temperatures make some windows hot to burst.

The sixth evaluation report of the Special Committee of the United Nations Intergovernmental Climate Change (IPCC) stated that global warming in the past 50 years has occurred at unprecedented speeds in the past 2000, and the unstable climate system has intensified. According to the analysis of the China National Climate Center, global warming is a frequent climate background of the high -temperature heat wave incident in the northern hemisphere.

The temperature continues to rise, and the high temperature record is constantly being broken. : "Science shows that with the intensification of global warming caused by human activities, the frequency and scale of extreme high temperature events will increase. Therefore, we will see more extreme hot weather. These weather will be more frequent than before, temperature, temperature, temperature, temperature, temperature, temperature, temperature, temperature, temperature, temperature, temperature, temperature, temperature, temperature, and temperature. It's higher than before. "

The British Meteorological Agency scientist Nicos Christie emphasized that the risks brought about by climate change are rapidly increasing, and extreme weather events are "becoming more and more common. By the end of this century, they will no longer be extreme events."

Coping climate change is imminent

The impact of climate change is very extensive, not only extreme temperatures and heat waves, but also affect ecosystems and agriculture and food production.

Extreme weather "is not only a natural disaster, but to a large extent is human disaster." The famous British climate and IPCC's sixth evaluation report core writing team member Friedlik Otto said, "Is every hot wave in the future? It will continue to be extremely fatal and destructive, which is also in our hands. "

The Secretary -General of the World Meteorological Organization Peter Tallas, wearing a tie symbolizing climate change at a press conference held in Geneva on the 19th that he hoped that the heat wave would sound a "alarm" for governments of various countries.

Some experts also pointed out that climate models may underestimate the changes in extreme high temperature compared with actual observation. Orto said, "Greenhouse gas emissions produced by fossil fuels such as coal, natural gas, and oil are making heat waves more hot, lasting and more frequent."

"Those who deny climate change really need time to see data and experience themselves. The whole society is imminent to take action to deal with climate change," Lecale said to reporters. "Unusual high temperature reflects a big trend, and the extremes of climate change are extreme. There are more and more peak temperatures. Before solving the problem of global climate change, there will be more similar situations. This is not simply a few sunny matters. In fact, the entire weather and climate change. , Society must make adjustments. "
