New Zealand's Seas Warming Faster than Global Average: Report

Researchers link New Zealand seas warming 34% faster than global average to disrupted ocean currents, causing marine heatwaves and threatening over 200,000 coastal homes.

  • Scientists released a new study on October 8 warning that climate change is rapidly worsening conditions in New Zealand's surrounding seas.
  • Researchers attributed the accelerated warming to disruptions in ocean currents between New Zealand and Antarctica, along with intensified atmospheric circulation patterns.
  • The 'Our Marine Environment' report highlights that New Zealand's surrounding seas are heating up at a rate 34% above the global average, with rising sea levels and increasing ocean acidity posing risks to both natural habitats and shoreline communities.
  • Between 1982 and 2023, sea-surface temperatures at four key monitoring locations rose by 0.16°C to 0.26°C each decade, while over 200,000 homes—collectively valued at about US$100 billion—are now in areas threatened by both coastal and inland flooding.
  • Marine advisor Shane Geange emphasized that sufficient proof now exists to warrant immediate measures, warning that postponing any response could lead to additional damage to marine ecosystems.
