  • The research says the world’s oceans are heating up at an accelerating pace as global warming threatens a diverse range of marine life and a major food supply for the planet


  • Ocean heating is a very important indicator of climate change and more rapid warming would only threaten our biodiversity and human life.
  • The study says about 93% of excess heat, trapped around the Earth by greenhouse gases that come from the burning of fossil fuels, accumulates in the world’s oceans.
  • Various scientific models have predicted that the temperature of the top 2,000 metres of the world’s oceans will rise 0.78 degrees Celsius by the end of the century if no measures were taken to reduce greenhouse gases
  • The thermal expansion, water swelling as it warms, would raise sea level 30 cm, above any sea level rise from melting glaciers and ice sheets.
