European countries, anxious about energy shortages, have been hit by extreme high temperatures. According to the provisional data of the Met Office, the temperature in Britain has reached an all-time high of 40.3 degrees Celsius in the past 24 hours, breaking the previous record in many regions. Forecasters warned that the temperature was still rising. France issued an extreme high temperature warning, and the Netherlands reported a record high temperature in July. Germany has experienced the hottest day so far this year, and the German meteorological agency has predicted that the western part of Germany may exceed the 40 ℃ mark this week. Italy is expected to have a high temperature of 40 degrees Celsius this week< Br > < div class= "contheight" > < /div> in addition to the record high temperature, the number of fire alarms is also surging. The southwest of France has experienced the worst wildfires in more than 30 years. The deadly wildfires in France, Spain, Portugal and Greece forced thousands of people to evacuate their homes. When recording the violent heat wave, European media said, “the fire broke out, the runway melted, the fire engines burned, and the temperature records rolled over”. So far, thousands of people have died in this heat wave< Br > < div class= "contheight" > < /div> “this is the third super heat wave that Europe has experienced since this year. Before that, the temperature in many regions hit a record high in May and June. The frequency of heat waves is higher and higher, and the temperature is also higher and higher, which is due to human induced climate change.”< Strong> Vikki Thompson, a climate scientist at the University of Bristol who has long studied extreme global climate, especially extreme high temperatures, explained to the news that since 1900, greenhouse gases in the atmosphere have increased the global average temperature by more than 1 degree Celsius. “The heat wave in Europe is accelerating, three to four times faster than other regions at the same latitude. This is because the change of high-speed air flow (jet stream) brings hotter air flow to the region more frequently. ”

Thompson told the news that record high temperatures have occurred all over the world. Large scale flows in the atmosphere will lead to high pressures in many regions at the same time, and high pressures lead to high temperatures. “If we want to stop the high incidence of heat waves, we need to reduce greenhouse gas emissions. We also need to adapt to these ‘new normal’ high temperatures and try to reduce the human health risks caused by heat waves.”< Br > < div class= "contheight" > < /div> “there are regional differences in heat waves.” Sjoukje Philip, a climate scientist at the Royal Dutch Institute of Meteorology (KNMI), analyzed that the heat wave in Western Europe is heating up faster than that in other regions, which is the result of multiple factors: soil drought, high-speed airflow changes, and often staying in the high-pressure area of the same place for a long time in India and Central America, the warming trend of heat waves is offset by some local factors, such as irrigation or air pollution< Br > < div class= "contheight" > < /div> due to changes in global weather patterns, extreme high temperature events do occur in natural climate changes. However, in recent decades, the increase in the frequency, duration and intensity of these events is obviously related to the observed global warming, which can be attributed to human activities. The World Meteorological Organization said on the 19th that the current heat wave sweeping Europe will continue until next week, and the negative effects of climate change such as high temperature will continue until at least the 1960s< Img alt= "extreme heat wave swept Europe, the highest temperature in the history of 40.3 degrees Celsius appeared in Britain, and many regions broke the previous record of the highest temperature" style= "width:600px;" src=" https://imagecloud.thepaper.cn/thepaper/image/206/713/409.jpeg ">
