Introduction
The oceans had their hottest June on record, with an average temperature of 20.98°C, surpassing the previous record of June 2024, which was 20.89°C. This information was released by the European Copernicus observatory, which also pointed out that the tropical Pacific recorded its hottest first half of the year since the start of the historical series in 1979, with 26.91°C.
The Impact of El Niño and Climate Change
The combination of El Niño and climate change could lead to new temperature records in the oceans this year. El Niño is a natural phenomenon that occurs when the surface temperature of the Pacific Ocean increases above average, affecting the climate worldwide.
The Mediterranean Sea: An Example of Sensitivity to Climate Change
The Mediterranean Sea is very sensitive to climate change and was affected by marine heatwaves in almost its entire surface (98%) in the first half of the year. As a result, the Mediterranean recorded a record temperature of 24.34°C in June.
Marine Heatwaves: A Risk to Marine Species
Since the beginning of the year, 82% of the world's ocean surface has recorded marine heatwaves, with half of them being intense to extreme episodes. Marine heatwaves are a risk to less mobile species, potentially causing mass deaths in corals, sea urchins, and mollusks.
Consequences and Perspectives
Oceans play a crucial role in regulating the climate, absorbing 90% of the excess heat generated by human activities. However, excessive heat absorption can lead to severe consequences, such as ocean acidification and loss of biodiversity.
Conclusion
Temperature records in the oceans are a warning sign for the need for urgent action to mitigate climate change. It is essential to reduce greenhouse gas emissions and protect marine ecosystems to ensure the health of the oceans and the planet.
