State of the Climate in Asia report

In News
  • Asia has warmed faster than the global average since 1960, the World Meteorological Organisation’s 2023 ‘State of the Climate in Asia’ report has said.
Major highlights
  • More than 2,000 people were killed and more than nine million were affected by extreme climate events across Asia in 2023.
  • More than 80% of these events were related to storms and floods.
  • The report also recorded several parts experiencing severe heat waves, leading to multiple fatalities, but acknowledged that heat-related mortality is widely underreported.
  • In India, severe heat waves in April and June killed around 110 people by heat stroke (a condition in which the body temperature increases beyond 40 degrees C).
  • A prolonged heat wave engulfed large parts of South and South-East Asia in April and May, affecting areas from Bangladesh and eastern India to southern China.
  • Local authorities also reported extraordinary temperatures from Thailand, Laos, and Vietnam.
  • In particular, North China experienced a significant heatwave from June 21 to July 9.
  • The highest temperature recorded at the Beijing Observatory was 41.1 degrees C, the second highest since records began in 1951.
  • Japan also experienced its hottest summer on record since 1898. Jeddah and Wejh in Saudi Arabia also experienced one heatwave each.
  • Heat tormented marine ecosystems as well.
  • The most severe to extreme heat waves occurred in a large part of the Arctic Ocean, in the Eastern Arabian Sea, and the Northern Pacific, lasting three to five months.
Floods & Storms in Asia
  • Similarly, tropical cyclone Mocha, which affected Myanmar and Bangladesh in May 2023, was the strongest cyclone in the Bay of Bengal in the last decade.
  • Shortly after, floods, landslides, and lightning killed around 600 people across India, Pakistan, and Nepal in June and July 2023.
  • In India, floods and landslides in August 2023, primarily in Himachal Pradesh and Uttarakhand, killed at least 25 and damaged a lot of infrastructure. Lightning by itself accounted for 1,200 deaths around India through the year.
  • The Hong Kong Observatory headquarters recorded an hourly rainfall total of 158.1 mm on September 7, the highest since records began in 1884.
  • Intense short-duration rainstorms in Yemen affected over 165,000 people and killed around 30.
  • Even Madinah in Saudi Arabia recorded a historically high amount of rain, on January 2.
  • In August and September, high precipitation linked to extratropical cyclones in Russia’s far east caused one of the largest disasters of the recent decade in terms of duration, extent, and economic losses.
  • Intense rains also triggered flash floods in Dubai and surrounding areas in November.
Early warning system
  • An early-warning system is an integrated process that monitors, predicts, and forecasts hazards.
  • It also includes activities related to risk-assessment, communications, and preparedness that allow individuals, communities, governments, businesses, etc. to take timely action to mitigate risks.
  • Experts have said such systems are integral parts of countries’ response to the increasing risk of natural disasters.
  • Twenty-one Asian countries reported the status of their early warning systems to the U.N.
  • According to the U.N. Office for Disaster Risk Reduction, the average composite score for the availability of and access to multi‑hazard early warning systems was 0.46 out of 1 in Asia; 0.58 for preparedness to respond; and 0.50 for observation and forecasting.
  • To compare, the world scored 0.35, 0.78, and 0.33, respectively, on average on these counts.
  • Warning and dissemination was the strongest area under the framework for Asia while risk knowledge was the weakest.
  • According to the report, fewer than half of all Asian countries have the tools with which to mitigate climate change impact.
