Sea also Rises
Context:
A recent study led by scientists at the Indian Institute of Tropical Meteorology warns of significant warming of the Indian Ocean and its dire consequences, including marine heatwaves, cyclones, coral bleaching, and impacts on the fisheries sector.
Impact of Warming Indian Ocean:
- Oceanic Changes and Implications: The study highlights the alarming increase in temperature of the Indian Ocean, projecting a rise of 1.7°C to 3.8°C by 2100. This warming trend is expected to lead to a tenfold increase in marine heatwaves, potentially pushing the tropical Indian Ocean into a "near-permanent heatwave state" with adverse effects on marine ecosystems and cyclone formation.
- Consequences for Mainland India: The warming of the Indian Ocean has far-reaching implications for mainland India, including a rise in the frequency of severe cyclones and erratic monsoon patterns. These phenomena, linked to global warming and anthropogenic activities like fossil fuel burning, pose significant challenges for infrastructure development and disaster management in coastal regions.
- Need for Collaborative Action: Given the slow response of oceans to changes in greenhouse gas emissions, current global commitments may not suffice to mitigate the impacts of ocean warming. Therefore, the study emphasizes the importance of collaborative efforts among Indian Ocean bordering countries to invest in data gathering, research, and infrastructure development to adapt to and mitigate the impacts of climate change on coastal communities.
