Ocean surface temperatures reached record highs for June, raising concerns about extreme weather patterns and climate impacts. According to The Guardian, temperatures outside the polar regions exceeded previous records set in 2023 and 2024 on June 21.

Al Jazeera reported that the European Union’s Copernicus Marine Service recorded global sea surface temperatures of 21.0 degrees Celsius, beating prior records. The rise is attributed to climate change and the onset of a potentially powerful El Niño event, which could further boost global heat in the oceans and atmosphere.

The record highs coincide with widespread marine heatwaves affecting around 82 percent of the global ocean, according to Al Jazeera. The Mediterranean, central North Atlantic, and equatorial Pacific emerged as hotspots. Scientists warn that these conditions could lead to more temperature records falling in the coming months.

The oceans absorb over 90% of excess energy from human-caused warming, primarily due to burning fossil fuels. This imbalance hit a record 23 zettajoules last year, equivalent to adding the energy of 11 Hiroshima atomic bombs to the oceans every second, as reported by UPI. The World Meteorological Organization warned that this excess heat is pushing Earth beyond its limits.

The Copernicus Climate Change Service director, Carlo Buontempo, cautioned that current conditions could indicate a new phase of uncharted territory. With ocean temperatures at these levels and El Niño on the horizon, more temperature records are likely to fall in the coming months.
