Ocean Warming क्या है?
ऐतिहासिक पृष्ठभूमि
मुख्य प्रावधान
8 points- 1.
Caused by the absorption of excess heat from the atmosphere, which is warming due to increased concentrations of greenhouse gases.
- 2.
Leads to thermal expansion of water, contributing significantly to sea-level rise.
- 3.
Reduces the ocean's capacity to absorb carbon dioxide, potentially accelerating atmospheric warming.
- 4.
Causes marine heatwaves, prolonged periods of unusually warm ocean temperatures, which can devastate marine ecosystems like coral reefs (leading to coral bleaching).
- 5.
Alters ocean currents and stratification, impacting nutrient distribution and marine productivity.
- 6.
Contributes to the intensification of tropical cyclones by providing more energy and moisture, leading to higher wind speeds and heavier rainfall.
- 7.
Leads to ocean deoxygenation, a reduction in the amount of dissolved oxygen in the ocean, creating 'dead zones' and threatening marine life.
- 8.
Impacts fisheries, coastal communities, and global weather patterns.

5 विकासGlobal ocean temperatures have reached record highs in recent years, with 2023 and 2024 seeing unprecedented warmth.
Increased frequency and intensity of marine heatwaves observed globally, including in the Indian Ocean.
Scientific studies increasingly link ocean warming to the observed changes in tropical cyclone activity in the North Indian Ocean.
Growing concern over the impact on monsoon patterns and marine biodiversity in the region.
Focus on improving ocean observation systems and climate modeling to better predict future impacts.
