Monday, July 3, 2023 is the hottest day globally since measurements began in 1979. The daily air temperature on the surface of the planet exceeded 17° C.
Never before has humanity recorded such a hot day globally as Monday, July 3, 2023. For the first timethe daily air temperature on the surface of the planet was measured at 17.01° C, according to measurements by the United States Agency for Oceanic and Atmospheric Observations (NOAA).
The measurement exceeds the previous daily record of July 24, 2022, of 16.92°C. The measurements are compared to a data set dating back to the year 1979. Now, the air temperature fluctuates between about 12 and 17°C daily average throughout the year. Between 1979 and 2000, it averaged 16.20° C at the beginning of July.
July 3, 2023, the hottest day on Earth. But for how long ?
” July 3, 2023, first time recorded that the Earth’s temperature exceeds 17°C. Remember this date. Decades from now, we will remember these 17°C with tenderness », comment on Twitter Bill McGuire, volcanologist and Emeritus Professor of Geophysical and Climate Hazards at University College London, on July 4. The day before, the scientist already pointed out that the average global temperature was approaching 17°C, believing that it was only a matter of days — weeks at most to exceed this threshold. It was even faster.
Moreover, if we change the scale, we see that ” the Earth breaks its absolute temperature record daily (all months combined) by a statistically incredible margin. 17.18° C beating yesterday’s 17.01 », emphasizes Serge Zakadoctor in agroclimatology.
The combination of El Niño and climate change
It is likely that this heat record will soon be broken. The northern hemisphere is just beginning the summer season and the average global temperature is expected to rise further through late July and early August. ” This is due to the combination of El Niño and climate change, and we may well see a few even warmer days over the next 6 weeks. », according to physicist Robert Rohdea graduate of the University of California at Berkeley.
The summer of 2022 was the hottest on record in Europe and, until the end, 2022 had been the year of climate emergency. The trends for the coming months are part of this continuity. Météo-France estimates that for the months of July, August and September 2023, ” the most likely scenario presents warmer than normal conditions throughout France.”
