Opening · a figure
As per IPCC, Indian ocean has been experiencing rise of [0.9°C] due to global climate change. This will have spiralling impact on marine ecosystem, coastal livelihoods and global climate.
Body · points
SEA SURFACE TEMPERATURE RISE
- Entails rise in the [surface water] of the sea
- Measured as [average] sea surface temperature measuring over months
- A [certain depth] of sea water is observed for measuring temperature
- [Causes] →
- Atmospheric heating (Temperature rise > 1°C)
- Rising evaporation of water
- Mixing of warm water from thermal plants
HAZARDS ASSOCIATED WITH SST RISE
Thermal expansion of water could lead to [coastal level rise] and [Subsidence of land]
Marine Heat waves due to high temperature → Coastal livelihoods impact → Marine ecosystem loss → Coral bleaching
Impact on upwelling and downwelling Can lead to sea stratification
Rising cyclones in the sea due to higher temperature → cyclone Ockhi → cyclone Biparjoy
Negative impact on Blue Economy due to mass extinction → Great Barrier Reef facing 6th Coral Bleaching
Storm Surges due to loss of natural Bio shields like Mangroves, corals.
Way Forward → ① Paris climate agreement to arrest rise in temperature → ② Nature Based Solutions like coral restoration, MISHMI → ③ Disaster Resilience under Sendai

Can act as guiding light to mitigate the climate change which has disastrous impact on the seas.
