Sea Level Rise

🔹 About:

1. An increase in the level of the world’s oceans due to the effects of climate change, especially global warming

🔹 Factor Influencing

1. Thermal Expansion

2. Melting Glaciers

3. Loss of Greenland and Antarctica’s ice sheets

🔹 Rate of Sea Level Rise

1. The average global sea level has risen 8.9 inches between 1880 and 2015. That’s much faster than in the previous 2,700 years.

2. Regional SLR may be higher or lower than Global SLR due to subsidence, upstream flood control, erosion, regional ocean currents, variations in land height, and compressive weight of Ice Age glaciers.

🔹 Consequences

1. Coastal Flooding

2. Destruction of Coastal Biodiversity

3. Dangerous Storm Surges

4. Lateral and Inland Migration

5. Impact on Infrastructure

6. Threat to Inland Life: 

7. Tourism and Military Preparedness

🔹 India's Effort

1. Setup of Coastal Regulation Zone

2. National Action Plan on Climate Change
