World's Hottest Day Recorded on July 21

On July 21, 2023, the world recorded its hottest day ever as the global average surface air temperature reached 17.09 degrees Celsius, surpassing last year's record. Heatwaves affected large parts of the United States, Europe, and Russia. Scientists anticipate that 2024 could become the hottest year on record due to climate change and the recent El Nino phenomenon.
July 21, 2023, was the hottest day ever recorded globally, as per preliminary data from the European Union's Copernicus Climate Change Service.

The global average surface air temperature reached 17.09 degrees Celsius (62.76 degrees Fahrenheit), surpassing the previous record of 17.08 degrees Celsius (62.74 degrees Fahrenheit) set in July last year.

Over the past week, heatwaves impacted extensive regions in the United States, Europe, and Russia.

Copernicus confirmed that last year's record temperature had been exceeded.

In 2022, a record was broken for four consecutive days from July 3 to July 6 due to climate change driven by fossil fuel combustion.

Since June 2023, each subsequent month has been the highest on record compared to previous years.

Scientists predict that 2024 might surpass 2023 as the hottest year due to ongoing climate change and the El Nino phenomenon, which ended in April but contributed to this year's temperature rise.
