Weather hits SE Asia economy
TORNADOS in the southern Philippines, tropical storms ravaging landlocked Laos – just a few of the severe weather aberrations happening across Southeast Asia right now.
According to risk analysts Verisk Maplecroft, these extreme weather events are likely to continue in the future given the impact of climate change and modern living environments.
A tornado swept through a coastal village in the Philippines on Sunday evening, toppling trees and tearing off roofs, injuring two people, police and disaster officials said.
Over 300 people fled to the village’s covered court as the whirlwind streaked across several communities in Barangay village Lapu-lapu in Agdao district shortly after 8:45pm, according to Chief Inspector Milgrace Driz, spokesperson of the Southern Mindanao police.
It was the latest severe weather anomaly to hit the country after Tropical Storm Josie passed over parts of the Philippines at the weekend killing five people, with six more missing.
In Laos, Khammuan and Borikhamxay provincial authorities have warned villagers living along rivers to be on alert of possible flooding after tropical storm Son-Tinh lashed northern and central provinces.
Flooding triggered by the same tropical storm over Laos affected 13 Thai provinces and 2,369 families between July 17 and 22, the Thai Department of Disaster Prevention and Mitigation said on Sunday.
Heavy rain triggered by Typhoon Son-Tinh has left 19 dead, 13 missing and 17 others injured in northern and northcentral provinces of Vietnam.
Floods also levelled 217 homes and damaged nearly 10,000 others.
According to the Crop Produc- tion Department at the Ministry of Agriculture and Rural Development, 59,000 hectares of rice and 2,000 hectares of maize and other crops in the Red River Delta were inundated.
‘Extremes more likely’
In the north-central region, nearly 51,000ha of rice and 13,400ha of maize and other crops sustained damages.
The UN has warned that “extreme weather events are set to occur more frequently” due to warming global temperatures.
Stanford researchers, who published their work in the journal Science Advances, analysed the likelihood of warm, dry, and excessively rainy periods in the coming years, all already exacerbated by rising global temperatures and sea levels.
The findings suggest that even if all countries met the commitments of the 2015 Paris climate agreement, heatwaves are five times more likely to occur in 50 percent of Europe and more than 25 percent of East Asia.
In addition, heavy rainfall is three times more likely to occur in 35 percent of North America, Europe and East Asia.
“Even if this better level were achieved, we would still be living in a climate with a much greater likelihood of unprecedented events than today,” says Noah Diffenbaugh of the Stanford Woods Institute for the Environment.
About 90 percent of North America, Europe, East Asia and the tropics “would see a marked increase in the risk of record heat, rainfall and/or drought.”
Verisk Maplecroft say that an estimated $300 billion is lost every year due to heat stress and climate change.
According to their data, Southeast Asia is the region set to experience the greatest loss in labour capacity due to heat stress, with a projected 16 percent decrease by 2045.
Singapore faces the greatest potential decline, with a projected 25 percent decrease, followed by Malaysia (24 percent), Indonesia (21 percent) and the Philippines (16 percent).
“Adaptation to the inevitable impacts of climate change – which under the UN Framework Convention on Climate Change is already on the same footing politically as reducing greenhouse gas emissions – will doubtless become increasingly important over the coming years,” the United Nations states.
