The week of July 3 to 9 was the hottest on record globally, the UN meteorological organization announced on Monday July 10, after several daily temperature records were broken. Following an already record month of June due to the combination of climate change caused by human activities with the first effects of the return of the El Niño weather phenomenon, temperatures are breaking records both on land and in the oceans.

The effects could be “devastating on ecosystems and the environment”, alerted the World Meteorological Organization (WMO). The current episode will likely continue with “at least moderate intensity”.

“We are in uncharted territory and we can expect more record breaking as the El Niño phenomenon develops and its effects are felt well into 2024.”

According to the European observatory Copernicus, Thursday July 6 was the hottest day, with an average temperature of 17.08°C, but with an insignificant margin for scientists of 0.02°C and 0.01°C on Wednesday and Friday. This series of unprecedented temperatures began on July 3 (16.88°C), beating the previous record of 16.80°C dating from August 2016, the hottest year ever measured by Copernicus, whose data goes back until 1940, when El Niño intensity was strong.
