The story thus far: Drought, floods, and excessive temperatures have been the crucial disasters that plagued Asiain 2022, inflicting intensive harm to life and property. In its 2022 State of the Climate in Asia report, the World Meteorological Organisation (WMO) summarised extreme climate events going down in Asia final yr, and their socioeconomic affect.
The report was ready in collaboration with the National Meteorological and Hydrological Services (NMHSs), analysis establishments, and businesses of the United Nations.
Global climate
Globally, the annual imply near-surface temperature in 2022 was 1.15 °C above the 1850–1900 pre-industrial common. Ocean warmth content material, the full quantity of warmth saved by the oceans, was the very best on report in 2022. Global imply sea stage too reached a brand new excessive in 2022 on account of ocean warming and accelerated loss of mass from ice sheets.
Key findings
According to the report, 2022 was the second or third warmest yr on report. Temperatures touched new highs, glaciers melted at unimaginable speeds, and Asia, and the world in normal, raced even additional in direction of a degree of no return.
Temperature
In 2022, imply floor temperature was both the second or third highest on report – 0.73 °C above the 1991–2020 common (reference interval used for computing anomalies in temperature and different indicators) and 1.6°C above the 1961–1990 common (WMO reference interval for assessing long-term climate change).
Northern Siberia, northern West Asia, Central Asia, and western and coastal areas of China famous above common temperatures in 2022. The yr was additionally the second warmest yr on report for China total.
Annual imply temperature anomalies (°C), 1900–2022, averaged over Asia, relative to the 1991–2020 common, for the six international temperature knowledge units indicated in the legend.

Research additionally exhibits {that a} warming pattern emerged in Asia in the latter half of the 20 th century. This pattern in 1991–2022 was virtually double the warming pattern throughout the 1961–1990 interval, and a lot bigger than the tendencies of the earlier 30-year intervals.
Trends in imply floor air temperature for the six WMO areas and the worldwide imply (°C) over 4 sub-periods utilizing the six knowledge units.

The area-averaged sea floor temperature anomalies in 2022 have been the warmest on report in the northwest Pacific Ocean, and have been under the report worth reached in 2020 in the Indian Ocean. Further, the Barents Sea in the Arctic Ocean has been recognized as a climate change hotspot.
Precipitation
Parts of Iraq, the Hindu Kush (the excessive mountain vary stretching from central to western Afghanistan), the decrease course of the Ganges and Brahmaputra Rivers (India and Bangladesh), the Korean Peninsula, and Kyushu (the western island of Japan) noticed the biggest precipitation deficits in Asia in 2022. Central Asia, the Yangtze River Basin (the place a extreme drought was reported) and the Huaihe River Basin in China, southwest and northwest Asia, and areas alongside the Arctic coast additionally recorded precipitation under regular.
On the opposite hand, south Pakistan, southeast Asia, and northeast China obtained extreme precipitation in 2022. Siberia, northeast Asia, central India, India’s Western Ghats, japanese Himalayas (Nepal and Bhutan), and areas alongside north China’s Yellow River and western Tian Shan (excessive mountain vary in western China) recorded unusually excessive precipitation.
India’s Western Ghats and Khasi Hills, and areas alongside the coast of the South China Sea and East China Sea recorded the very best each day precipitation totals in 2022. Positive anomalies with respect to the very best each day precipitation totals have been additionally detected in elements of Iran and Iraq. This exhibits that extreme precipitation events may happen even when the annual complete is under regular.
Glaciers
Preliminary knowledge exhibits that in the glaciological yr 2021-22, 23 glaciers in the High Mountain Asia area confirmed continued discount in their lots. In the 2021-22 interval, Urumqi Glacier No. 1 in japanese Tien Shan recorded its second most detrimental mass steadiness since measurements started in 1959.

Extreme events: Cyclones
In 2022, 25 named tropical cyclones with most sustained wind speeds of 34 knots or extra fashioned over the western North Pacific Ocean and the South China Sea. Nanmadol hurricane, which made landfall in Japan’s Kyushu area on September 18, 2022, was the strongest tropical cyclone of the yr. Almost 4 million individuals have been instructed to evacuate, whereas it reportedly affected 1,300 individuals, killed 5, and triggered financial harm value greater than US$2 billion.
Three tropical cyclones, and 15 cyclonic disturbances (the place wind velocity was larger than 27 knots) fashioned over the north Indian Ocean in 2022.
Floods
Pakistan witnessed extreme floods in the 2022 monsoon season between June and September. According to authorities, virtually 14% of the nation’s inhabitants was displaced consequently of the floods, whereas 1,730 individuals died and round eight million have been displaced. The floods destroyed 1.7 million hectares of agricultural land, forcing tens of millions in direction of poverty and meals insecurity.
Heavy monsoon particularly affected Northeast India, in addition to neighbouring Bangladesh the place the floods cumulatively killed 2,000 individuals and affected 1.3 million individuals. This was the worst pure catastrophe affecting India in 2022.
Droughts
Yangtze River basin in southwest China, house to a 3rd of China’s inhabitants, skilled its worst drought in six a long time in the summer time of 2022. An intense heatwave in central-eastern China, together with average precipitation deficit, triggered the drought.
The water from the Yangtze River is used for crop irrigation, transportation and power manufacturing, and the domino impact from the drought impacted every little thing. The Three Gorges Dam, the biggest hydropower plant in the world, can also be situated alongside the Yangtze River. The approximate financial loss from droughts in China in 2022 amounted to US$ 7.6 billion.
Iran was one other Asian nation adversely impacted by drought in 2022, its third consecutive yr of drought. The floor space of Lake Urmia, which has shrunk by 95% over the previous three a long time, continued to lower in 2022.
Other extreme events in India
India and Pakistan skilled unusually heat circumstances in the pre-monsoon season, between March and May. Further, lightning, accompanied by thunderstorms, has change into one of the largest killers in India in the latest years. In May 2022, greater than 34 individuals killed as a result of lightning in Bihar.
Impact on the financial system
Economic losses brought on by floods in 2022 exceeded the common noticed over the previous 20 years. The most important losses have been seen in Pakistan (over US$ 15 billion), China (over US$ 5 billion) and India (over US$ 4.2 billion).

Economic damages related to drought in Asia have been famous to be round US$ 7.6 billion in 2022. For different disasters, the financial harm was milder. In the case of storms in specific, Asia misplaced round US $3.3 billion, which was virtually 80% decrease than the 2002–2021 common of US$ 16.2 billion.
