The gradual increase in global ocean levels due to thermal expansion and melting ice sheets. A major threat to low-lying Southeast Asian coasts and islands.
climateWhat is Sea Level Rise?
Global sea level has risen about 20 cm since 1900 and is currently rising at 3.6 mm per year (accelerating). Southeast Asia is one of the most vulnerable regions: Jakarta is sinking and faces submersion risk, Bangkok is only 1.5 metres above sea level, the Mekong Delta could lose 40% of its area by 2100, and Pacific island nations face existential threats. Indonesia is moving its capital partly due to sea level and subsidence concerns.
