- Sea Level Rise - The Maldives
- Causes
- thermal expansion of oceans
- melting of west Antarctic ice sheet
- complete melting of Greenland ice sheet
- collapse _ melting of west world's glacier systems
- areas vulnerable
- low-lying island in pacific + indian oceans
- World largest river deltas - Brahmaputra - River Ganges
- areas that already lie close to sea level - east coast of England
- Why difficult to predict?
- difficult to estimate future GHG emissions
- whether we adopt business as usual model
- difficult to predict impact of thermal expansion of oceans + melting of ice sheets
- Isostatic Change
- change in the sea level due to change in amount of water in oceans
- Eustatic Change
- movement of land (loss or gain of mas) e.g. melting of ice sheet lead s to uplift
- The Maldives
- Impacts
- islands will be uninhabitable after 20 years
- salt water incursion
- 80% of 1,200 islands are no more than 1m above sea level
- flooding due to storm surges
- destruction of setteled areas
- infrastructure and houses washed away
- weather becoming less predictable
- due to alignment of stars no longer give guidance
- Coping strategies
- reconstructed islands
- natural defenses - Coral reefs
- Kandhol Hudoo - 60% of residents plan to evacuate over next 15 years
- 3m sea wall ($63) protects 200 inhabited islands against short term impacts of tidal surges
