The European Union's climate monitoring agency, the Copernicus Climate Change Service, and the 'Copernicus Marine Service' jointly issued a bulletin on the 1st, stating that the global average sea surface temperature set a new historical record for the same period on June 21.
According to data from the Copernicus Climate Change Service, the global average sea surface temperature on June 21 rose to 20.86°C, higher than the 20.83°C recorded during the same period in 2023 and 2024. Data from the 'Copernicus Marine Service' show that the global average sea surface temperature on the same day reached 21°C, 0.1°C higher than the record set in 2023 and 2024.
The bulletin stated that this new record for high sea surface temperatures is related to the conditions for the formation of El Niño in the tropical Pacific region. The World Meteorological Organization issued a bulletin on June 2, pointing out that considering factors such as the abnormally warm waters in the tropical Pacific, there is an 80% probability of an El Niño event occurring between June and August, with the risk of extreme weather increasing in the coming months.
Buoentenbo, Director of the Copernicus Climate Change Service, stated that the current situation may indicate that we are very likely to see more temperature records broken in the coming months.
In recent months, abnormally high sea surface temperatures have been observed in many marine areas around the world. The bulletin warns that high sea surface temperatures may affect weather patterns, increasing the risk of storms, extreme rainfall, and flooding, exacerbating sea-level rise and ice melt, and putting pressure on marine ecosystems, fisheries, and coastal economies.
