Rescuers and relatives searched knee-deep in water for the body of one-year-old Zara. She'd been swept away by flash floods; the bodies of her parents and three siblings had already been found days earlier.

We suddenly saw a lot of water. I climbed up to the roof and urged them to join me, Arshad, Zara's grandfather, said, showing the BBC the dirt road where they were taken from him in the village of Sambrial in northern Punjab in August.

His family tried to join him, but too late. The powerful current washed away all six of them.

Every year, monsoon season brings deadly floods in Pakistan.

This year it began in late June, and within three months, floods had killed more than 1,000 people. At least 6.9 million were affected, according to the United Nations agency for humanitarian affairs, OCHA.

The South Asian nation is struggling with the devastating consequences of climate change, despite emitting just 1% of global greenhouse gas emissions.

To witness its effects, the BBC travelled from the mountains of the north to the plains of the south for three months. In every province, climate change was having a different impact.

There was one element in common, though. The poorest suffer most.

Scenes played out across the province, with rescuers delayed due to uprooted trees and major infrastructure being destroyed. A helicopter carrying aid crashed in the bad weather, claiming the lives of all crew on board.

Architect Yasmeen Lari has designed what she calls 'climate-resilient houses' in dozens of villages, aiming to combat the devastating impacts of flooding.

However, experts warn that as climate change progresses, flooding events will grow more severe and frequent, leading to a cycle of disaster that sees millions displaced and struggling for recovery.
