Since the beginning of this year, Europe, Asia and the Americas have experienced extreme weather.
After a record-breaking spring in the northern hemisphere, EU climate agency monitoring shows that the world's temperature in the first 11 days of June reached an all-time high,This year is expected to overtake 2016 as the hottest year on record.
Since the World Meteorological Organization (WMO) issued an El Niño warning in early May, extreme high temperature events around the world have continued unabated.
In the United States, Texas and many states along the Gulf Coast have experienced extreme high temperatures in the past few days. Among them, Houston, Brownsville and other places in Texas have experienced temperatures close to 50°C.
In Europe, the intensification of the climate crisis has led to the continuous decline of groundwater levels. On June 15, the European Parliament issued a stern warning on the water crisis.
In India, nearly 100 people have died in the past few days in the country's two most populous states;In Pakistan, the highest temperature in the southwest of the country reached 50 ℃ on June 16, and the hospital was blocked by heatstroke patients "......
Burgess, deputy director of the Copernicus Climate Change Service, said that with the arrival of the El Niño climate phenomenon, next year will be hotter than this year.
Recently, Texas, Louisiana, Mississippi and Florida in the southern United States have been experiencing high temperatures.According to US media reports, more than 40 million people in the United States are facing a heat alert.
According to news released by the National Weather Service, many parts of the southern United States along the Gulf Coast encountered high temperatures on the 17th, with somatosensory temperatures ranging from 46 to 49 degrees Celsius in Houston and Brownsville, Texas.
Pratt, an expert at the National Weather Service, said that due to the proximity to the Gulf of Mexico, the air humidity in these places is high, causing the body temperature to soar. In Dallas, for example, a local temperature of 34 degrees Celsius will bring a body temperature of 40.5 degrees Celsius.

In addition, many states in the southern United States have suffered extreme weather such as high temperature and heavy rain for several days, causing a large number of residents to interrupt power supply.
On the 15th, the town of Perryton in Texas was also hit by a strong tornado, causing power outages for nearly 50000 users in the local area and neighboring Oklahoma in the north. At present, the Gulf Coast and a number of nearby U.S. cities have opened summer centers for residents of the home power to cool off.
Ning Kidd, the head of the Federal Emergency Management Agency in Texas, said that there may also be extreme weather such as rainfall and strong winds in the short term, and even more tornadoes.
The U.S. Power Data Network updated information on the 18th,More than 600000 people were still without power in many southern U.S. states that day..
Tornadoes spawned by high-temperature weather have recently hit Texas, Florida and other states in the southern United States, killing several people, Reuters reported.
Recently, according to the Associated Press, Indian officials said that in the past few days, at least 96 people in the country's two most populous states have died due to high temperatures.
The deaths occurred in the northern Indian state of Uttar Pradesh and the eastern state of Bihar, where the local government has warned residents over the age of 60 and others with underlying diseases not to go out during the day.
According to data from the Indian Meteorological Department, the highest temperature in Balia District of Uttar Pradesh reached 43°C last Sunday, 5°C higher than normal.
In addition, the relative humidity in the area reached 25%, which further exacerbated the impact of high temperatures. The extreme heat caused power cuts across the region, people were without running water, and many people staged protests.
According to reports, the deaths caused by the high temperature are all elderly people over 60 years old, and they may have deteriorated their physical condition due to the high temperature before.
In fact, extreme high temperature is not only extremely dangerous for the elderly with basic diseases such as high blood pressure and heart disease, but also can cause serious harm to ordinary people.
A study recently released by the Scientific American shows that when humans are exposed to extreme heat, their central nervous system, brain and other important organs will be affected, and the effects will appear at a very fast rate, leading to heatstroke, heat cramps, etc.
In addition, extreme heat is especially dangerous for people with chronic diseases. Among them, the elderly are at higher risk, and children may not be able to regulate their body temperature as effectively as adults in extreme climates, so they are also vulnerable.
In the United States, extreme heat is also the number one cause of death related to weather. In most years, extreme heat causes more deaths than hurricanes, floods and tornadoes combined. However, studies have shown that people are often less prepared for extreme heat and less aware of the dangers compared to disasters such as storms and wildfires.
The study also pointed out that extreme heat waves are a threat to all levels of society, but people in dense urban environments will suffer the most.
As more and more people around the world move to urban areas, the link between urbanization and heat risk will become more urgent.
