Rising sea levels serious threat to Asian cities, may put 15 mn people at risk by 2030: Greenpeace report

The draft stated, "Difficult choices will need to be made as sea level continues to rise, floods and storm surges become more frequent and intense, warming increases ocean acidity and intensifies heatwaves." Rising sea levels and stronger tropical cyclones are putting coastal communities across Asia in danger of flooding. By 2100, the IPCC 2019 predicts a rise of 0.43-0.84m in global mean sea level.“Within this decade, coastal cities in Asia are at high risk from rising sea levels and intensifying storms, impacting our homes, safety and livelihoods. Not only is it long past time to halt the construction of all fossil fuel projects, but governments must implement increased flood control and early warnings," Mikyoung Kim, climate urgency project manager at Greenpeace East Asia."Existing climate commitments, including nationally determined contribution targets, are insufficient to avert the risk of severe coastal flooding,” she added.Because land, population, and GDP are among the most essential resources for economic development, a precise estimate of the possible effects of sea-level rise is critical for making decisions about how to protect them.An estimated 600 million people in total – majority of who live in Asia – will be affected by rising sea levels in areas that are low lying, coastal regions, area with a high risk of flooding or all of the above.  Some of these areas are economic centres with significant gross domestic product (GDP).[caption id="attachment_9772851" align="alignnone" width="1350"] 2030 predictions for sea level rise.

• If a 10-year flood occurs in 2030, more than 96 percent of Bangkok's land area might be flooded, including high-density residential and commercial sectors in the city centre.
• Jakarta is threatened by both rising sea levels and sinking. If a 10-year flood occurs in 2030, over 17 percent of Jakarta's total land area is below the level at which sea-water could reach, posing a US$68 billion GDP risk.
• Eastern Tokyo's low-lying neighbourhoods, including Sumida, Koto, Adachi, Katsushika, and Edogawa Wards (Sumida, Koto, Adachi, Katsushika, and Edogawa), are particularly vulnerable to increasing sea levels. Coastal flooding in Tokyo threatens $68 billion in GDP in 2030 or seven percent of the city's overall GDP.
• The ancient Datong District in Taipei, as well as Taipei Main Station, the most important transport hub in northern Taiwan, are at risk of flooding. It is anticipated that 24 percent of Taipei's overall GDP could be impacted.
• If a 10-year flood occurs in 2030, over 87 percent of Manila's land area is below the level to which sea-water could rise. A total of 1.54 million individuals and US$39 billion could be impacted.
