Vietnam and the Philippines are used to durations of intense rain, however local weather change threatens to make these occasions extra extreme. Southeast Asia as a complete faces an escalating local weather threat, due its densely populated cities, frequent heavy rain, and inadequate infrastructure.
Latest modelling from Zurich Resilience Options discovered that six main cities in Southeast Asia—Singapore, Bangkok, Ho Chi Minh Metropolis, Jakarta, Kuala Lumpur, and Manila—all face not less than a “excessive threat” of maximum precipitation, heatwaves, and rising sea ranges via the 2040s.
Specifically, the modelling famous that Manila, Bangkok, Singapore, and Jakarta are amongst Southeast Asia’s most climate-vulnerable cities, with crucial infrastructure dealing with excessive publicity to a number of local weather hazards.
Zurich’s threat modelling used knowledge factors from seaports, airports, and notable cultural websites, like Bangkok’s Grand Palace and Manila’s Fort Santiago. The evaluation was performed below the SSP2-4.5 situation, a extensively used projection developed Intergovernmental Panel on Local weather Change. The “middle-of-the-road” pathway assumes average world mitigation efforts and anticipates a two diploma Celsius improve in world common temperatures between 2041 and 2060.
“In Manila, websites are at extreme threat from excessive precipitation, storm surge, sea degree rise, and flooding, threatening commerce and cultural preservation,” the report’s authors wrote. Each Bangkok and Jakarta are additionally threatened by worse flooding from local weather change.
Zurich notes that governments are already investing to handle a few of these dangers.

Not investing in mitigation might lead to extreme monetary losses. A current report from the World Financial Discussion board and Singapore Worldwide Basis estimates that the impression of local weather change might scale back Southeast Asia’s GDP by as much as 25% by 2050.
One other examine from Oxford Economics estimates {that a} 1% improve in common temperatures might increase meals costs throughout Vietnam, Thailand, Malaysia, Indonesia and the Philippines.
Companies within the area are additionally taking discover of how local weather change’s monetary price might hit their very own operations.
Metropolis Developments Restricted (CDL), No. 139 on the Southeast Asia 500, estimated in 2023 that local weather inaction might price 120 million Singapore {dollars} ($93.2 million) by 2030, equal to virtually 4% of its 2024 income. CDL is engaged on one other local weather situation examine to be revealed later this yr.
