NEWS – A research by Indian Institute of Tropical Meteorology (IITM), Pune has revealed Ocean Warming Trends in Indian ocean

HIGHLIGHTS

• Ocean Warming Trends
  • Indian Ocean warmed by 1.2°C from 1950-2020.
  • Expected further warming of 1.7-3.8°C from 2020-2100.
• Impact on Marine Environment
  • Increase in marine heatwaves, linked to cyclone formation.
  • Predicted tenfold rise in marine heatwaves, affecting ecosystems adversely.
  • Predictions of near-permanent heatwave state, coral bleaching, and ecosystem loss.
• Ocean Heat Content
  • Deeper ocean layers also warming, increasing overall heat content.
  • Predicted increase in heat content equivalent to one Hiroshima atomic bomb detonation every second.
• Contribution to Sea-Level Rise
  • Thermal expansion of water from ocean heating.
  • Major contributor to sea-level rise in the Indian Ocean.
