The surface of the oceans experienced the warmest May ever recorded, the European organization announced Copernicus.

“Ocean surface temperatures are already reaching record highs, and our data shows that the average temperature of all ice-free seas in May 2023 was warmer than any other May.”says Samantha Burgess, Deputy Director of the European Copernicus Climate Change Service (C3S), in her announcement.

The announcement is based on computer analyzes of a multitude of measurements taken from satellites, ships, planes or weather stations around the world. The data used by the Copernicus service goes back to 1950.

As for global temperatures, May was the second warmest on record.

“May 2023 was the second warmest globally, while at the same time we are watching the El Niño phenomenon continue to develop in the tropical Pacific Ocean,” explains Samantha Burgess.

El Niño is a natural climate phenomenon associated with rising temperatures, increased drought in some regions of the globe, and heavy rainfall in others.

It developed for the last time in 2018-2019 and gave way to a La Niña episode that lasted almost three years and causes opposite effects and mainly a drop in temperatures.

In early May, the World Meteorological Organization estimated that there is a 60% chance of El Niño developing between now and the end of July, and an 80% chance between now and the end of September.

This spring was the warmest and driest recorded in Spain

The meteorological spring, which runs from March 1 to May 31, was the warmest on record in Spain since the country’s climate statistics began, it announced today the National Meteorological Service (Aemet).

The season, marked by an exceptional heat wave at the end of April, was also the driest on record, Aemet said in a report.

During these three months, the average temperature in Spain was 14.2°, which is 1.8° above normal for spring and 0.3° above the previous warmest spring record in 1997.

Masses of warm and dry air that arrived from North Africa at the end of April caused a record rise in the temperature in southern Spain to 38.8°, a temperature corresponding to the month of July.

“Extreme heat would be almost impossible without climate change.” showed a scientific study published in early May by the World Weather Attribution (WWA), a global network of scientists assessing the relationship between extreme weather events and climate deregulation.

In contrast, May was characterized by temperatures on average lower than normal for the season, according to Aemet.

Episodes of extreme high temperatures have multiplied in recent years in Spain, which is at the forefront of Europe’s countries threatened by climate change. 75% of its territory is at risk of desertification, according to the UN.

According to Aemet, 2022, with its extremely high temperatures and devastating fires, was the hottest year ever recorded in Spain.
