Asia, the world’s most populous continent, is warming twice as fast as the rest of the world, according to the latest State of the Climate in Asia 2024 report by the World Meteorological Organization (WMO) released on Monday.

In 2024, Asia’s average temperature was about 1.04°C above the average for 1991 to 2020, ranking as the warmest or second warmest year on record, depending on the dataset.

Sea surface temperatures were the highest on record, and as a result, sea level rise on the Pacific and Indian Ocean sides of the continent exceeded the global average, heightening flooding risks for low-lying coastal areas.

The heat has also adversely affected the marine ecosystem and coastal communities that depend on the oceans for their income.

“The State of the Climate in Asia report highlights the changes in key climate indicators such as surface temperature, glacier mass and sea level, which will have major repercussions for societies, economies and ecosystems in the region. Extreme weather is already exacting an unacceptably high toll,” said WMO Secretary-General Celeste Saulo at the launch of the report.

This heat has also caused rainfall patterns to change, and widespread heatwaves. In the central Himalayas and Tian Shan in Kyrgyzstan, 23 out of 24 glaciers suffered mass loss, leading to an increase glacial lake outburst floods and landslides and heightened  long-term risks for water security.

In addition, extreme rainfall and tropical cyclones that are worsening with high temperatures have wreaked havoc in the region.

Pace of warming has quickened

In 2024, Asia’s average temperature was about 1.04°C above the 1991–2020 average. The warming trend between the years 1991–2024 was almost double of that during the 1961–1990 period, indicating that the pace of warming has quickened.

Asia is warming so fast because it is the continent with the largest land mass, extending all the way to the Arctic, and land is warming more than the ocean, according to the report.

Prolonged heatwaves were reported across Asia in countries like China, Japan and the  Republic of Korea. Myanmar set a new national temperature record of 48.2°C in 2024, testing the limits of human endurance.

Rising ocean heat, melting glaciers

Most of the ocean area of Asia was affected by intense marine heatwaves , with the Northern Arabian Sea and the Pacific Ocean particularly affected, according to the report.

“Average sea surface temperatures increased at a rate of 0.24°C per decade, which is double the global mean rate of 0.13°C per decade,” the report said.

“During August and September 2024, nearly 15 million square kilometres of the region’s ocean was impacted – one tenth of the Earth’s entire ocean surface, about the same size as the Russian Federation and more than 1.5 times the area of China.”

This heat has also affected glaciers. The Himalayan region is often called the ‘Third Pole’ as it has the largest reservoir of frozen fresh water outside of the two poles. Ice cover here spans an area of around 100,000 sq km or roughly the size of Egypt.

Reduced snowfall during the winters coupled with hot summers is leading these life-sustaining glaciers to melt at a record pace. Billions of people living downstream in countries like India, Bangladesh, Nepal and China are affected as some of the world’s largest rivers – including the Ganga, Brahmaputra and the Yangtze – originate from these glaciers.

Glaciers in other mountain ranges in Asia are also melting at a faster rate. “Urumqi Glacier No.1, located in the eastern Tian Shan, recorded its most negative mass balance since measurements began in 1959,” the report read.

In addition to this, extreme events like cyclones and erratic rainfall have caused widespread damage across the region, the report said.

India’s Kerala state reported 350 deaths following extreme rainfall that triggered landslides on 30 July last year. The following month, floods in Nepal killed 246 people and caused $94 million damage to property.

In China, nearly 4.8 million people were affected by drought, which is estimated to have cost more than $400 million in direct losses.

The elephant in the room

What the report did not mention was Asia’s toxic air which, apart from worsening health indicators, has also been pushing up rates of glacier melt.

Nearly all of the world’s most polluted 50 cities in 2024 are in Asia, particularly in the densely populated Indo-Gangetic plain, which includes Pakistan, India and Bangladesh, according to data from IQAir, a Swiss air quality technology company.

Black carbon, or the soot left behind after the incomplete combustion of fossil fuels,  drives higher rates of glacier melt as it settles on ice, darkens the surface and causes higher absorption of sunlight. When in the air, black carbon absorbs sunlight and traps the heat, warming the air further.

Silver lining: Early warning systems

However, amidst the largely grim scenario, there was a silver lining. The report mentioned the case study of Nepal, nestled in the Himalayas, which has invested in early warning systems and managed to save lives. Climate monitoring helped officials to anticipate extreme weather events and reduce damage.

WMO has been pushing countries to invest in early warning systems for extreme weather events like floods and cyclones, which can anticipate risk and prepare communities to respond to climate change. This helped them protect lives and livelihoods.

“The work of National Meteorological and Hydrological Services and their partners is more important than ever to save lives and livelihoods,” Saulo said.
