World’s Oceans Hit Highest Temperature on Record as El Niño Grows
Global ocean surface temperatures have climbed to their highest level on record, scientists have confirmed, with researchers pointing to the strengthening El Niño weather pattern as a key driver behind the alarming milestone.
The record was described as “another clear signal of an ocean under growing stress” by Dr Samantha Burgess of the European Copernicus Climate Change Service, the monitoring body responsible for tracking global temperature data.
El Niño, a natural climate cycle originating in the Pacific Ocean, periodically raises sea surface temperatures and can intensify weather extremes around the world. When combined with the longer-term warming trend driven by greenhouse gas emissions, scientists warn that its effects are being amplified, pushing ocean temperatures into unprecedented territory.
Rising ocean temperatures carry significant consequences for marine ecosystems, weather systems, and coastal communities. Warmer seas fuel more intense storms, contribute to coral bleaching events, disrupt fish populations, and accelerate the melting of polar ice — all of which have cascading effects on both biodiversity and human livelihoods that depend on healthy oceans.
The latest data adds to a growing body of evidence that 2023 and 2024 have been exceptional years for climate records, with land and sea temperatures repeatedly surpassing previous highs. Scientists have consistently linked these trends to human-caused climate change, warning that without significant reductions in carbon emissions, such records will continue to be broken with increasing frequency.
