Climate change kills two million in 50 years — UN

A report by the United Nations has revealed that extreme weather conditions have caused the deaths of two million people and $4.3 trillion in economic damage over the past half a century.

According to the new figures published on Monday by the UN’s World Meteorological Organisation, 11,778 weather-related disasters have occurred from 1970 to 2021, and they have surged over that period.

The report also showed that more than 90 per cent of deaths were reported worldwide due to the disasters that took place in developing countries.

“The most vulnerable communities, unfortunately, bear the brunt of weather, climate and water-related hazards. Cyclone Moncha, which wreaked havoc in Myanmar and Bangladesh last week, exemplified this reality,” WMO chief Petteri Taalas said in a statement.

The severe storm “caused widespread devastation, impacting the poorest of the poor”, he said.

But the WMO mentioned that improved early warning systems and coordinated disaster management had significantly reduced human casualties.

Taalas pointed out that during disasters similar to Mocha in the past, “both Myanmar and Bangladesh suffered death tolls of tens and even hundreds of thousands of people.” Myanmar’s military government has put the death toll from the latest cyclone at 145, but there are fears the number is higher.

In a 2021 report covering disaster-linked deaths and losses from 1970 to 2019, the agency pointed out that at the beginning of the period, the world saw more than 50,000 such deaths each year. By the 2010s, the disaster death toll had dropped to below 20,000 annually.

And in its update of that report, the WMO said on Monday that 22,608 disaster deaths were recorded globally in 2020 and 2021 combined.

“Thanks to early warnings and disaster management, these catastrophic mortality rates are now thankfully history,” the report said. “Early warnings save lives.”

The UN has launched a plan to ensure all nations are covered by disaster early warning systems by the end of 2027. To date, only half of the world’s countries have such systems in place.

Economic losses

The WMO, meanwhile, warned that while deaths have plunged, the economic losses incurred in weather-related disasters have soared.

The agency previously recorded economic losses that increased sevenfold from 1970 to 2019, rising from $49 million per day during the first decade to $383 million per day in the final one.

Wealthy countries have been hardest hit by far in monetary terms.

Developed nations accounted for more than 60 per cent of losses due to weather, climate, and water disasters, but in more than four-fifths of cases, the economic losses for each disaster were equivalent to less than 0.1 per cent of gross domestic product.
