Brutal heat a global warning

ASIA remains in the grip of a blistering heat wave, chiming with predictions from climate scientists that 2023 could be the world’s hottest year.

In an ominous sign ahead of the northern hemisphere summer, an emerging El Nino weather pattern is pushing temperatures to unprecedented levels in southern parts of the continent.

Vietnam reported its highest ever temperature of 44.2°C over the weekend, triggering power shortage warnings, while Laos also likely broke records. The Philippines cut classroom hours after the heat index reached the “danger” zone, reflecting the potentially deadly combination of heat and humidity.

The scorching temperatures follow a pattern of increasing extreme weather in recent years that’s sending the world into uncharted territory.

The sweltering conditions are testing the ability of governments to protect public health and also to prevent major disruptions to agriculture and power generation in economies that are still recovering from Covid-19.

El Nino – characterised by warmer ocean temperatures across the Pacific – has far-reaching impacts on weather patterns around the world. It could bring relief to drought-parched areas of Argentina and the southern US, while blanketing parts of Asia and Australia with hotter, drier conditions. Coffee, sugar, palm oil and cocoa crops would be very vulnerable.

Temperatures in Thailand remained above 40°C in many northern and central regions over much of last week, pushing power demand to a fresh peak. Businesses and banks have asked the government to prepare an action plan to deal with a potential drought that they say might last for three years.

Rainfall in Malaysia may be as much as 40% lower in some areas, which could put palm oil production at risk in one of the world’s biggest producers of the commodity. Authorities are closely monitoring the return of forest fires and air pollution. An El Nino in 2015 caused a particularly bad episode of haze that was one of the worst environmental disasters ever in Southeast Asia.

Elsewhere in Asia, scorching temperatures have also roasted parts of China, India and Bangladesh over the past few weeks. Yunnan province, a major aluminium hub in southwest China, suffered its worst drought in a decade last month.

India is on alert for more heat waves after soaring temperatures in April prompted school closures in some states and caused at least 11 deaths from heatstroke. — Bloomberg
