What is sea surface temperature rise? Explain the hazards associated with rise of sea-surface temperatures (10 Marks, 150 Words)
Introduction
Per IPCC, Indian ocean has been experiencing since 0.1-0.2°C rise due to global climate change. This will have severe rolling impacts on marine ecosystem, coastal livelihoods and global climate.

SEA SURFACE TEMPERATURE RISE
1Salts arise in the surface water of the sea
2Measured as average sea surface temperature prevailing over months
3A certain depth of sea water is observed for measuring temperature
4Causes: Atmospheric heating (temperature rise) + Rising evaporation of water + Mixing of warm water from thermal plants
HAZARDS ASSOCIATED WITH SST RISE
1Thermal expansion of water could lead to coastal dead zone and subsidence of land
2Marine heat waves due to high temperature → coastal livelihoods impact → Marine ecosystem loss (ED) coral bleaching
3Impact on upwelling and downwelling can lead to sea stratification
4Rising cyclones in the sea due to higher temperature (El cyclone and cyclone binary)
5Negative impact on blue storing due to mass extinction (for Great Barrier Reef being 6th largest bleaching)
6Storm surges due to loss of natural porousness due magnets, corals
Way forward towards:
Can act as guiding right to mitigate the climate change within has catastrophic impact on the seas
