Summer 2024 was hottest since records began, says EU's climate change monitoring service

The planet experienced it warmest-ever ever summer on average, making it likely this year will end up being the warmest since records began.
The new data comes just days after it was confirmed that summer 2024 was Ireland's coldest since 2015.
Climate change and the El Niño weather phenomenon, which warms the surface waters in the eastern Pacific, have both consistently pushed temperatures to record highs across the world over the course of this year.
In its monthly bulletin, the Copernicus Climate Change Service (C3S) said the global average temperature anomaly from January 2024 to August 2024 is 0.70°C above the 1991-2020 average, the highest on record for this time period, and 0.23°C warmer than the same period in 2023.
The average global temperature would need to decrease by 0.3C during the final four months of this year for last year’s overall record not to be broken.
“In order for 2024 not to become the warmest on record, we need to see very significant landscape cooling for the remaining few months, which doesn’t look likely at this stage,” said Copernicus director Carlo Buontempo.
C3S says the average global temperature over the last three months was 16.8C, 0.03C warmer than the old record set last year.
With an average temperature of 16.82C, August 2024 and August 2023 are now tied for the hottest Augusts on record.

This July was the first month in more than a year in which a new temperature record was set.
However, because the July 2024 average was only marginally lower than that of July 2023, and because June 2024 was also warmer on average than June 2023, summer 2024 was still the hottest ever on the whole.
"During the past three months of 2024, the globe has experienced the hottest June and August, the hottest day on record, and the hottest boreal summer on record," said 3CS Deputy Director Samantha Burgess.
"This string of record temperatures is increasing the likelihood of 2024 being the hottest year on record.”
In Europe, the average temperature for August 2024 was 1.57°C above the 1991-2020 average for that month, making it the second-warmest August on record, just behind the all-time record for August set in 2022.
Though European temperatures in August were above average across southern and eastern Europe, they were below average in Ireland, the UK, Iceland, the west coast of Portugal, and southern Norway.
Temperatures were above average in eastern Antarctica, Texas, Mexico, Canada, northeast Africa, Iran, China, Japan, and Australia, and below average in eastern Russia, the eastern US, parts of southern South America, Pakistan, and in the Sahel.
“The temperature-related extreme events witnessed this summer will only become more intense, with more devastating consequences for people and the planet unless we take urgent action to reduce greenhouse gas emissions."
