Our greenhouse gas emissions continue to increase global temperatures. And while we have just experienced the first year of heat over 1.5 ° C, scientists emphasize that it is now a question of life for the growing part of the population … or death!
The year 2024 was recorded with a heat level above +1.5 ° C compared to the pre -average. If the temperature continues to climb this rate, we can cross the door of +2 ° C from the middle of our century. An additional increase of half a degree, this can be important. But scientists have been repeating it for many years now IssueIssue Global warming is counted every tenth degree.
Do you know?
Extreme heat is already a great threat to human life. Since 2000, more than 260,000 heat deaths have been recorded worldwide during the deadliest episodes. XXI’s three highly fatal episodesE The century collectively caused 200,000 deaths, which included nearly 72,000 in Europe, 62,000 in Europe in 2022, and about 56,000 in Russia in 2010.
Appeared in the work journal Nature Review Earth and Environment By researchers from Kings College London (UK) Give an instance I have a cold ThatThat. So far, the doorstep HeatHeat In the oldest places in the world and already in the hottest places, the fatalities are only briefly exceeded. But with the temperature of +2 ° C, it will reach the door for a very large part of the population. “A long exposure out – even for those living in the shade, a sharp air and well hydrated – can cause a fatal heat, including young and healthy people.”Warned Tom Mathews, LecturerLecturer In environmental geography Kings College London.
Already deadly temperature
Researchers have reported that between 1994 and 2023, the threshold of tolerance – understands the combination of temperature and humidity that the human body may not face – about 2 of the surface surface of the ground surface surface levels. About 2 % exceeded, about 60 years of age. For older people, the affected level was already more than 20 %.
Fully understanding you, you should know that here is a question that scientists call the doorstep «Disqualification of disqualification». Name Body temperatureBody temperature Human Middle East begins to become control. The doorstep of clay “Uncontrolled” So far only has been crossed for older people. They are described“Uncontrolled” Because they only increase the body temperature to 42 ° C in just six hours. Unfortunately, we imagine continuity …
A threat that grows for all populations
With the heat of +2 ° C, these doorsteps “Uncontrolled” Can also be crossed for people under 60. So far without going, the amount of land related to conditions «Disqualification of disqualification» There should be three times for young people. Go from 2 to 6 %. This is equal to the United States area! The part of the land where more than 60s is at risk will reach close to 35 %.
If the heating level is still climbing, logically things will deteriorate (unfortunately we unfortunately take). With the temperature +4 or +5 ° C, about 60 % of the Earth’s surface will be inaccessible to ancient ancient. And existing trends do not exclude such scenarios.
Researchers also said that some regions are more at risk of crossing the critical limit «Disqualification of disqualification» And “Uncontrolled”. Saharan Africa and South Asia’s population is at the highest risk. But if the temperature continues to rise, only high -rise and cold regions of the average substance can be saved. Thus today it seems necessary to improve understanding that we have the fatal capacity of extreme heat installments, so as to assess the costs of failure of global warming reduction measures, but also in the communities efforts. Can be targeted This is most needed.
