The thermometer shows 39 degrees in the area of Prasa-da-SS in San Paulo. A year after the UN calling for actions to combat extreme heat, the world is again in the fire The climate and the environment this week has been a year since the publication of the call of the UN Secretary General to combat extreme heat. This date coincided with the new destructive waves of heat, covering many countries, which again emphasized the importance of early warning and systemic measures in the field of thermal health. On the occasion of the anniversary of the call, the global information network on thermal health, together with the World Meteorological Organization (VMO) and the UN Office to reduce the risk of disasters, used new resources as part of a joint initiative, the purpose of which is to support the management of the risks and coordination of measures to adapt countries and communities to increase growth temperatures. 60 ~ h2 > quiet threat that kills ~ 60 > at the end of July of this year, meteorologists predict dangerous and prolonged heat in the southeast states of the United States, which will affect more than 20 million people. According to the National Meteorological Service of the United States, the heat index, taking into account both temperature and humidity, will reach 43–46 degrees Celsius and remain until the beginning of August. The countries of North Africa and the Middle East are now experiencing no less suffering: serious interruptions in the supply of water and electricity are recorded in Iran. Mediterranean and Balkans are already experiencing a third wave of heat over the summer, which paralyzes agricultural and construction work and delivers a serious blow to human health. ~ 60 > new temperature records extreme temperatures became the cause of destructive forest fires, from which Türkiye, Greece and Cyprus suffered. They carried away human lives, forced thousands of people to leave their homes and enveloped the sky with thick smoke over entire regions. In Turkey, in the city of Silopi, a new temperature record is set – 50.5 degrees Celsius. In Cyprus, the temperature reached 44.6 degrees Celsius, which also became a record for July. In Greece, Italy and Spain, due to the heat, it was necessary to temporarily close popular tourist attractions. Even the Scandinavia felt an abnormal heat: in Finland for more than 15 days in a row, the temperature exceeded 30 degrees Celsius, a similar situation is observed in Norway and Sweden. The region has a high risk of forest fires. according to the European Copernicus service, June became the hottest in the history of observations for Europe, and on a global scale – the third. Unusually high temperatures in the western part of the Mediterranean Sea reinforced the thermal load in Western and southern Europe. heat as a result of climate change according to the deputy general of the URRETT Secretary, extreme heat, extreme heat often They call a “quiet killer”, but taking into account modern scientific data, technologies and monitoring systems, there is nothing to justify inaction. Each death from the heat could be prevented. according to modeling estimates, from 2000 to 2019, about 489 thousand were related to the heat of deaths a year. Of these, 45 percent accounted for Asia, 36 percent – for Europe. However, experts emphasize that in many countries thermal diseases and fatal cases are often not officially recorded. ~ 60 > most scientific research recognize the direct relationship between extreme heat and climate change caused by emissions of greenhouse gases. extreme heat has already become a “new norm”. Global initiatives to prevent and protect the population should keep up with accelerating climatic changes. The life of millions depends on the speed and effectiveness of these actions.
