What led the planet to have the hottest day ever recorded – 7/5/2023 – Environment
[ad_1]
The average global temperature reached a new record on Monday (03/07), reaching 17ºC for the first time.
US researchers say the figure is the highest since satellite monitoring began in 1979, and possibly since there are records from older instruments dating back to the late 19th century.
Scientists at the US National Centers for Environmental Prediction said the global average temperature reached 17.01°C on July 3, breaking the previous record of 16.92°C in August 2016.
Scientists believe that a combination of the natural El Niño weather event and humanity’s continued carbon dioxide emissions are adding to the heat.
Last month was also confirmed as the hottest June on record in the world.
Experts are concerned about rising temperatures on land and at sea.
The record spring heat in Spain and many countries in Asia was followed by heat waves at sea in places where this is highly unusual, such as the North Sea.
This week, China continued to suffer from a long-lasting heat wave, while the southern US is also experiencing sweltering conditions.
“The average surface air temperature reaching 17°C for the first time since we have reliable records is a significant symbolic milestone in our warming world,” says climatologist Leon Simons.
The El Niño Southern Oscillation, or Enso, has three different phases: warm, cold, or neutral. It is the most powerful fluctuation in Earth’s climate system.
“Now that the warmest phase of El Niño is starting, we can expect many more daily, monthly and annual records over the next year and a half.”
Karsten Haustein of the University of Leipzig confirms this expectation.
“Chances are that July is the hottest month ever: since ‘ever’ means since the Eemian period, about 120,000 years ago,” says Haustein.
“While Southern Hemisphere temperatures will drop slightly over the next few days, chances are July and August will see even warmer days as El Niño is in full swing.”
