The hottest day in recorded history has been observed worldwide

The average global temperature reached a new record on Monday, July 3, exceeding 17°C for the first time ever. This is the highest value observed in history.

"The average global near-surface air temperature reaching 17°C for the first time since we have reliable data is a significant symbolic milestone in global warming," said climate researcher Leon Simmons.

The record was caused by a combination of carbon dioxide emissions and the El Niño weather phenomenon, which is expressed in fluctuations in the temperature of the surface layer of water in the equatorial part of the Pacific Ocean.

On July 3, the average global temperature reached 17.01°C, according to the National Centers for Environmental Prediction in the USA. The previous record of 16.92°C was set in August 2016.
