Monday was warmer than the previous July 21, which itself narrowly beat the all-time highest temperature.
The Earth languished for a second day in a row with record temperatures on July 22, the EU climate watchdog said.
Preliminary data from the Copernicus Climate Change Service (C3P) showed that on Monday (July 22), the global average daily temperature was 17.15 degrees Celsius - the warmest in their records, which date back to 1940.
This was 0.06 °C warmer than the previous day on July 21, which itself narrowly beat the all-time highest temperature set just a year earlier.
"This is exactly what climate science has been telling us will happen if the world continues to burn coal, oil and gas," said Joyce Kimutai, a climatologist at Imperial College London.
"And it will continue to get hotter until we stop burning fossil fuels and achieve net zero emissions."
Copernicus, which uses satellite data to update global air and sea temperatures in near real time, said its data was preliminary and the final values could vary slightly.
He expects daily records could continue to fall as summer is in full swing in the Northern Hemisphere and the planet is experiencing an unusual period of unprecedented heat following the hottest year on record.
On July 23, the watchdog said global temperatures are expected to drop soon, although further fluctuations are possible.
Global warming is leading to longer, stronger and more frequent extreme weather events, and this year has been marked by major disasters around the world.
The historic heat was felt across many continents, including Asia, North America and Europe, where heatwaves and wildfires have wreaked havoc in recent weeks. | BGNES
