Since June this year, heat waves have hit many countries in the northern hemisphere. The United Kingdom, France and South Korea issued high temperature warnings, and many places in Japan and the United States broke records. Experts have attributed this summer’s “scorching” pattern of heat in the northern hemisphere to climate change and warned the public to protect themselves.
Rarely high temperature
The Met Office issued the first ever red warning for unusually high temperatures on the 15th. The UK Health and Safety Authority also issued the first level 4 warning since the introduction of the high temperature health warning in England in 2004 – “national emergency”. The Met Office expects the unusually high temperature to affect much of England, including London, early next week, with a maximum temperature of 40C, with an 80% chance of setting a record for the UK’s highest temperature. The highest temperature ever recorded in the UK was 38.7 degrees Celsius, which was measured at the University of Cambridge Botanic Gardens on July 25, 2019.
World Meteorological Organization spokesman Naris said in Geneva on the 12th that a new heat wave is forming in Western Europe, and this heat wave is expected to intensify and spread. The heat could spread to the rest of Europe in the next few weeks.
The French Meteorological Service said that France will usher in high temperature weather for up to 10 days from the 12th. The French meteorological agency announced that seven provinces are under an orange warning for high temperature, and dozens of other provinces are under a yellow warning.
A heat wave from North Africa has hit the Iberian Peninsula in southwestern Europe since the 8th, causing continuous high temperatures in Portugal and Spain on the island for several days. Coupled with the rare drought and low rainfall this year, forest fires in Portugal and Spain are frequent. The two governments, with the help of the European Union, have mobilized their forces to deal with the sweltering heat. Many other European countries also sounded the heat wave warning.
South Korea’s Ministry of Administration and Security issued a high-temperature orange warning on the 2nd, covering most of the country. The warning was issued 18 days earlier than last year. In South Korea, when the temperature of more than 40% of the country reaches 33 degrees Celsius for at least 3 consecutive days, the high temperature orange warning will be activated.
Affected by high pressure, the temperature in most parts of Japan has risen sharply since late June, and Tokyo has continued to have high temperatures for several consecutive days. Among the 914 observation points in the country, 338 observation points observed the highest temperature in the history of June observation.
In mid-June of this year, the southwestern region of the United States suffered a heat wave, and the high temperature in many places broke records. The Phoenix branch of the National Weather Service reported that on June 11, the highest temperature in Phoenix, the capital of Arizona, reached 46 degrees Celsius, setting a record for the same day since 1918.
Researchers from the UK Met Office pointed out that climate change has triggered unprecedented extreme weather events on a global scale. Corinna Le Carre, a professor of climate change at the University of East Anglia in the United Kingdom, said in an interview with Xinhua News Agency on the 16th that climate change has led to an increase in extreme high temperature weather around the world, and the speed of climate change is faster than the adaptive actions of human society.
The World Meteorological Organization believes that due to climate change, extreme high temperatures are expected to appear more frequently and more intensely in the future. The group’s spokesman, Naris, previously said that if greenhouse gas emissions continue to rise, global warming will be even greater, and what is currently experienced is only a “harbinger of the future.”
The previous assessment report released by the United Nations Intergovernmental Panel on Climate Change (IPCC) pointed out that in the last 50 years, global warming has occurred at an unprecedented rate since the past 2000 years, and the instability of the climate system has intensified.
How to protect
The Hungarian National Center for Public Health reminds the public to strengthen protection in high temperatures, such as drinking plenty of water; pay attention to sun protection between 11:00 and 15:00, and protect the skin from sunburn with appropriate clothing and sunscreen; do not put children or pets Stay in the car under the scorching sun.
Met Office chief executive Penny Endersby called the UK’s extreme heat warning “absolutely unprecedented” and urged the public to take it seriously. The UK Met Office warned that hot weather may lead to water and power outages in some areas, interruption of communication services, etc., and people need to adjust their daily life and work methods and reduce outdoor activities.
In response to high temperature weather, the South Korean Ministry of Administration and Security has asked relevant departments and local governments to take measures to provide help and health protection for outdoor workers, elderly people living alone and other groups.
The Japanese government calls on the public to take measures to prevent high temperature-related diseases, and at the same time pay attention to avoid heat stroke and use air conditioners appropriately.
