Pakistan's largest city battered by torrential rain as climate crisis makes weather more unpredictable

Public services in Pakistan's largest city, Karachi, have been suspended and businesses are being urged to close, as torrential rains cause deadly flash flooding and infrastructure damage, leaving at least 15 dead since Saturday.

On Sunday night, more than 60 millimeters (2.3 inches) of rain fell in Karachi, equivalent to an entire months' worth of rainfall in just a matter of hours.

For several months every summer, Pakistan struggles to contend with heavy monsoon rains, but in recent years experts say climate change is accelerating existing weather patterns.
