Bad weather for the climate. According to the latest data from National Centers for Environmental ProtectionJuly 3 was the hottest day on Earth. This news raises concerns about human-induced global warming and the resurgence of El Niño.

Monday 3 July The global average temperature was 17.01°Caccording to an analysis conducted by researchers at the University of Maine using data collected by National Centers for Environmental Forecasting (National Center for Environmental Predictions, US Centers for Environmental Prediction).

This is the highest average global temperature ever recorded on Earth, according to data analysis, breaking the previous record of 16.92°C, which was set on July 24, 2022 and August 14, 2016.

Climate experts have attributed this phenomenon to a combination of human-caused global warming and the return of El Niño, a weather phenomenon that occurs every two to seven years due to wind patterns in the Pacific Ocean and is known to cause higher temperatures around the world. .

The Intergovernmental Panel on Climate Change (IPCC) notes that due to human activity, the Earth’s surface temperature has increased by 1.1°C over the period 2011-2020 compared to the period 1850-1900, leading to more wildfires, floods and reduced food supplies across the country. the world.

According to the World Meteorological Organization, El Niño has returned this year and is expected to cause global temperatures to rise over the next nine to twelve months.

The World Meteorological Organization said it expects 2024 to be similar to 2016, the hottest year on record, which was so hot because of a “double effect”: El Niño and human-caused global warming, a dynamic the organization says is on repeat.

“Although the NCEP CFSR data only begins in 1979, other datasets allow us to go back even further and conclude that this day was warmer than any since instrumental measurements began, possibly a long time ago,” he said. . wrote Tuesday on Twitter Robert Roddy, the chief scientist at Berkeley Earth, an American nonprofit organization focused on environmental data science and analysis. Global warming takes us to an unknown world. »
