Last Sunday was the hottest day ever recorded on Planet Earth , says the European Union.
Our Earth had the hottest day ever recorded this past Sunday, the 27th. The news comes from the European observatory Copernicus. The average global air temperature on the surface reached 17.09°C, a heat never before recorded. The previous record had also occurred in July, but in the year 2023, when the average global temperature was 17.08°C.
The data is still preliminary, according to the observatory, but points to a historical daily record in the Copernicus records, which have been made since 1940. June of this year marked the thirteenth uninterrupted month of heat records on Planet Earth . Since June 2023, a hotter month has been recorded in each new period, a fact that scientists and authorities highlight to indicate that we are living in a climate emergency. June’s temperature mark adds to the list of global heat records this year and last.
— First , our planet recorded in 2023 the hottest June in history – until then .
— Then , the record was broken with each new month: July, August, September, October, November, December, January, February, March, April, May and now June again.
— In addition , the number of days that exceeded the politically significant warming threshold of 1.5ºC has already reached a new high ;
— And, to make matters worse , for the first time, the world recorded a day with the global average temperature 2°C above the pre-industrial era.
— In addition to all this , July 2023 was so hot that it may have been the hottest month in 120,000 years , while average September temperatures broke the previous record by 0.5°C.
Several regions of the Earth will be uninhabitable
NASA, the American space agency , has published a study listing five regions of the planet where heat could make human survival impossible in the next 50 years. The list includes areas in the Central -West, Northeast, North and Southeast of Brazil . The study was led by Colin Raymond, from NASA’s Jet Propulsion Laboratory, and published in the scientific journal Science Advances.
The list also includes South Asia, the Persian Gulf and the Red Sea, as well as parts of China and Southeast Asia . In addition to the uninhabitable areas, the study also indicates that, in the same period, some regions will no longer allow the formation of life.
In February of this year, NASA had already indicated that planet Earth is 1.5 degrees warmer. The researchers used satellite images and projections of the wet bulb temperature, the lowest temperature that can be reached solely by the evaporation of water . In addition to temperature, air humidity was also taken into account.
According to experts, the combination of a temperature equal to or greater than 37ºC and humidity above 70% is what triggers health problems. The body can maintain sweating at 45°C with 20% humidity. However, with humidity above 40%, it can be lethal , since the ability to sweat and dissipate heat is reduced. It is not known how humans can adapt to high temperatures for several days.
