Global ocean temperatures hit record high as El Nino intensifies

Summary

The global average sea surface temperature reached a new record high of 21.1 degrees Celsius in August, according to the European Union’s Copernicus Climate Change Service. This increase is driven by a strong El Nino event and long-term human-caused warming, creating significant stress on oceans and marine life.

Key Facts

  • Sea surface temperatures hit 21.1°C (69.98°F), breaking the previous record set earlier in 2024.
  • The El Nino weather pattern is intensifying and adding extra heat to the oceans.
  • Normally, ocean temperatures peak in March or April, but this year’s record was in August.
  • Oceans have warmed by about 0.8°C (1.44°F) due to fossil fuel emissions over decades.
  • Warmer oceans cause sea levels to rise by expanding water and threaten marine life like coral reefs and seagrass.
  • Rising temperatures reduce the ocean’s ability to absorb carbon dioxide, a natural way to fight climate change.
  • Higher ocean heat can lead to stronger storms and extreme weather events worldwide.
  • The warming ocean affects food supplies, economic activities, and coastal communities.
