Over two million deaths and $4.3 trillion in economic losses; that’s the impact of a half-century of extreme weather events turbo-charged by man-made global warming, the World Meteorological Organization (WMO) said on Monday.
According to WMO, weather, climate and water-related hazards caused close to 12,000 disasters between 1970 and 2021. Developing countries were hit hardest, seeing nine in 10 deaths and 60 per cent of economic losses from climate shocks and extreme weather. WMO issued its new findings on the human and economic cost of weather-induced disasters for its quadrennial World Meteorological Congress, which opened on Monday in Geneva with a focus on implementing the UN’s Early Warnings for All initiative.
WMO said that Least Developed Countries and Small Island Developing States suffered a “disproportionately” high cost in relation to the size of their economies.
“The most vulnerable communities unfortunately bear the brunt of weather, climate and water-related hazards,” said WMO Secretary-General Petteri Taalas.
In Least Developed Countries, WMO reported that several disasters over the past half-century had caused economic losses of up to 30 per cent of gross domestic product (GDP).
In Small Island Developing States, one in five disasters had an impact “equivalent to more than five per cent” of GDP, with some disasters wiping out countries’ entire GDP.
Asia saw the highest death toll due to extreme weather, climate and water-related events over the past 50 years, with close to one million deaths – more than half in Bangladesh alone.
In Africa, WMO said that droughts accounted for 95 per cent of the reported 733,585 climate disaster deaths.
The initiative aims to ensure that early warning services reach everyone on Earth by the end of 2027. It was launched by UN Secretary-General António Guterres at the COP27 climate change conference in Sharm al-Sheikh in November last year.
