World's oceans break June heat record, says EU monitor

The oceans have never been warmer. They hit a record 21 degrees celcius average surface temperature in June, logged by Copernicus, the EU's Earth-observation programme. It's clearly taking a toll on biodiversity around the world, after years of warnings from experts. The onset of a potentially powerful El Nino weather pattern could boost global heat in the oceans and atmosphere even further in 2026 and into next year.
