Question 15GS3GS1
Examine the impacts of climate change on the hydrological cycle and suggest suitable mitigation and adaptation strategies to contain the harmful implications.
Introduction
Hydrological cycle regulates concentration of water in atmosphere, lithosphere and water bodies.

Main Body
[Impact of climate change on cycle]
1Melting of ice caps & glaciers due to global warming (1.5°C already risen - IPCC)
2Sea level rise & island sinking
3Increase humidity (wet bulb temperat) with 4°C rise => 7.5 increase in humidity.
4Increasing rate of vaporisations from oceans => impact on cloud formation & water cycle
5Positive feedback loop & vicious cycle — intensify the impact.
6Impact on ocean salinity — flow of freshwater into sea
7Disruption of proportion of fresh & brine water — 97.5 saline water ~ 3.5 fresh water.
These changes require mitigations & adaptation —
1[Mitigation] => (1) Halting global warming (Climate & Carbon Neutral)
2Achieving 1.5° target (Paris Conference)
3Afforestation & green infra for enhancing foundation in ground water.
4Halting glacier melting
[Adaptation]
1Resilient small island initiative (IRIS)
2Managing water refugees
3Structural measures —
Aquifers, check dams, Bioshields - Carbon tanks, Capturing water discharge - prevent flooding, Charcoal, Carbon filter sludge
