Asia was the world's most disaster-hit region from climate and weather hazards in 2023, the United Nations said on April 23, with floods and storms the chief cause of casualties and economic losses.

Global temperatures hit record highs last year and the UN's weather and climate agency said Asia was warming at a particularly rapid pace.

The World Meteorological Organization (WMO) said the impact of heatwaves in Asia was becoming more severe, with melting glaciers threatening the region's future water security.

The WMO said Asia was warming faster than the global average, with temperatures last year nearly two degrees Celsius above the 1961-90 average.

"The report's conclusions are sobering," WMO chief Celeste Saulo said in a statement.

"Many countries in the region experienced their hottest year on record in 2023, along with a barrage of extreme conditions, from droughts and heatwaves to floods and storms, she said.

Climate change exacerbated the frequency and severity of such events, profoundly impacting societies, economies, and, most importantly, human lives and the environment, Saulo said.

"Asia remained the world's most disaster-hit region from weather, climate and water-related hazards in 2023," the WMO said.

The annual mean near-surface temperature over Asia in 2023 was the second highest on record, at 0.91 degrees Celsius above the 1991-2020 average, and 1.87 C above the 1961-1990 average.

Last year, 79 disasters associated with water-related weather hazards were reported in Asia. Of those, more than 80 percent were floods and storms, with more than 2,000 deaths and nine million people directly affected.
