The threat of rising sea levels (PG 10)(GS 3)
Current Affairs- 28 APRIL 23
•What is the rate at which sea levels are rising? What are the reasons behind the accelerated sea-level rise?
• What does the report by the World Meteorological Organisation show?
•What problems can be caused by rising sea levels?
The WMO has found in a new report that the world’s sea level is rising at an unprecedented rate, portending potentially disastrous consequences for the weather, agriculture, the extant groundwater crisis, and social disparities.
The sea level has been rising in the three decades for which satellite altimeter data is available (19932022). But, while the rate of sealevel rise was 2.27 mm/year in 19932002, it shot up to 4.62 mm/year in 20132022.
Since the lives of coastal communities, including their economic activities, is tied intricately with the coastal ecosystem, changes in the coastal ecosystem as a result of GSML rise will further endanger the socioeconomic stability of these communities
