The World Meteorological Organization (WMO) recently said that the past July was the highest temperature in the world since records were made. Some parts of Europe were affected by a long-term strong heat wave, and the Antarctic sea ice range also dropped to the lowest value in the same month since records were made. The World Meteorological Organization predicts that due to climate change caused by human activities, high-temperature heat waves will appear more and more frequently in the future, and the temperature in Europe will rise faster than that in other regions. According to the World Meteorological Organization, July this year is one of the three hottest July months on record globally, nearly 0.4 degrees Celsius higher than the reference period from 1991 to 2020. The land temperature in the northern hemisphere is generally higher than the average level. Take Europe as an example. Most of the areas here are drier than before. The precipitation in some countries has fallen below the record, which has seriously hit the local economy, especially agriculture, and increased the risk of wildfires. This unusually hot and dry weather continued in August. According to the data, Portugal, Spain, France and some parts of the United Kingdom all experienced high temperatures above 40 ° C in July, of which the United Kingdom exceeded 40 ° C for the first time; The number of days with the highest temperature exceeding 35 ° C in the Iberian Peninsula is also unusually large, highlighting the persistent high temperature in this region. July, the third warmest month on record, also occurred in the United States. Most areas experienced several rounds of heat waves with daytime temperatures exceeding 37.8 degrees Celsius, leading to a surge in energy demand and cases of high-temperature related diseases. The temperature in many areas of Central South America and southern Africa is above the average, and the sea temperature near the North Pacific and Antarctic Peninsula is also above the average. Under the attack of abnormal drought and high temperature, the precipitation in most parts of Europe in July is lower than the average level. The precipitation in some parts of the West has fallen below the record, and some places in the southwest and Southeast have experienced drought. This not only affects the local economy, but also increases the risk of wildfire spreading. According to the Copernicus climate change service, from the Iberian Peninsula to the Black Sea, including the United Kingdom and Ireland and the southern Scandinavia, as well as parts of western Russia and the Caucasus, the precipitation, soil humidity and relative humidity continue to be lower than the average level. Local precipitation records show that some parts of France and Britain experienced the driest July. The average rainfall of France in that month decreased by 84% compared with the average value of July since 1991. In the past few months, the persistent severe drought is affecting agriculture and energy management in many areas due to heat waves and lack of rainfall. The drought in Spain, Greece and the Czech Republic has caused wildfires to spread. Much of North America is also drier than average. According to the US drought monitoring report on August 2, more than half of the United States is in a state of drought, and wildfires are raging in the western and southern plains. From January 1 to July 31 this year, more than 2.31 million hectares of land in the United States were burned, nearly 1.5 times the average level of previous years. The World Meteorological Organization said that at least in some parts of Europe, the trend of high temperature and little rain will continue in August. The Met Office issued an extreme high temperature warning on August 9. It is expected that the temperature in southern England will rise, but it will not be as extreme as in July.
