The world’s largest and most populous continent is reckoning with the deadly effects of extreme summer weather, as countries endure blistering heatwaves and record monsoon rainfall, with governments warning residents to prepare for more to come.

This month torrential rains inundated parts of Japan, China, South Korea and India, upending the lives of millions and causing flash floods, landslides and power cuts. Record temperatures also led to a rise in heat-related illnesses, particularly among vulnerable communities such as the elderly.

On Saturday, at least 13 people in the central South Korean city of Cheongju died after waters from a burst riverbank flooded an underpass, trapping vehicles, including a public bus.

At least 41 people have died in South Korea in recent days and thousands more have been forced to evacuate their homes and seek temporary shelter, as heavy downpours hit central and southern parts of the country.

In response to the loss of life, South Korean President Yoon Suk Yeol called for an overhaul of the country’s approach to extreme weather.

“This kind of extreme weather event will become commonplace — we must accept climate change is happening, and deal with it,” Yoon said Monday.
