Main Body

Oceans are a great source of carbon sink absorbing CO2 in various forms. However in recent years, the absorption has led to ocean acidification (IPCC report). Oceans - allied in fight against climate change: (1) Carbon sinksCO2 absorbing than forest ecosystems over longer period of time. (2) Heat balancethrough Atlantic meridional circulation/overturning (AMO94) ocean currents lead hot water of equator towards poles. (3) Provision of livelihood to help people fight climate change.
4Upwelling leading to high fisheries. (1) Oceans help in removing wind systems to distribute heat generated due to climate change. (2*) Atmospheric meridional circulation. However, oceans themselves have been affected: (1) Marine heat waves → Indian ocean region. (2) ENSO cycles → El Niño leading to ocean heating. (3) Ocean acidification → high (CO2 absorb) leading to H2CO3 acid formation. (4) Coral bleaching incident. (Ep*) UNEP 1.5°C rise → 35% global coral will be bleached. (5) Extreme weather events in heated → intense ocean cyclones → more destruction. Way forward → IPCC targets, INDCs, COP 26 goals, adherence Global collaboration UNEP, Therefore SDG 11/17 and MSDT require collaboration of state across the countries to save the oceans.
