Recent weeks have seen record-breaking heatwaves across Asia, with countries like Japan, South Korea, and Vietnam experiencing unprecedented temperatures and tropical nights. Experts link these extreme weather events to climate change, which is causing the region to warm faster than the global average. Curious about what's driving these heatwaves, the risks involved, and whether Asia can adapt? Keep reading to find out more.

Which regions in Asia are experiencing the worst heatwaves?
Japan, South Korea, and Vietnam are currently facing some of the most severe heatwaves. Japan recorded its hottest day ever at 41.2°C, while South Korea experienced 22 tropical nights in July, with temperatures staying above 25°C overnight. Vietnam saw its first-ever August day above 40°C in Hanoi. These regions are experiencing extreme heat that is impacting daily life, health, and infrastructure.

How is climate change making these heatwaves worse?
Climate change is causing Asia to warm nearly twice as fast as the global average. This accelerated warming leads to more frequent, intense, and prolonged heatwaves. Human activities, such as burning fossil fuels and deforestation, increase greenhouse gases in the atmosphere, trapping more heat and raising temperatures across the region.
-
What health risks are linked to these heatwaves?
Extreme heat increases the risk of heatstroke, dehydration, and other heat-related illnesses. Hospitals in affected countries are seeing a surge in heatstroke cases, and vulnerable populations like the elderly and outdoor workers are at higher risk. Prolonged heat can also worsen existing health conditions and cause long-term health problems.
-
What infrastructure challenges do these heatwaves create?
High temperatures strain electricity grids due to increased demand for cooling. Water shortages become more severe as evaporation rates rise and water sources dry up. Infrastructure such as roads and railways can also be damaged by extreme heat, leading to disruptions and economic losses.
-
Can Asia adapt to these rising temperatures?
While some adaptation measures are underway, such as improving cooling systems and water management, the rapid pace of climate change makes adaptation challenging. Governments are urged to implement stronger climate policies, invest in resilient infrastructure, and promote sustainable practices to better cope with future heatwaves.
-
Is climate change the only reason for these heatwaves?
While natural variability can influence weather patterns, the current extreme heat events are strongly linked to human-induced climate change. Scientific studies show that climate change is increasing the frequency and severity of heatwaves worldwide, including in Asia.
