ISLAMABAD, Pakistan (AP) — Nearly a half-million people crowded into camps after losing their homes in widespread flooding and the climate minister warned Monday that Pakistan is on the “front line” of the world’s climate crisis after unprecedented monsoon rains wracked the country since mid-June, killing more than 1,136 people.

The rains stopped more than two days ago and floods in some areas were receding. But Pakistanis in many parts of the country were still wading through waters that filled their homes or covered their town’s streets as they struggled with how to deal with the damage to homes and businesses.

Climate Minister Sherry Rehman and meteorologists told The Associated Press that new monsoons were expected in September. Monsoons have hit earlier and more heavily than usual since the start of summer, officials say — most recently with massive rains last week that affected nearly the entire country.

Pakistan is accustomed to monsoon rains and flooding, Rehman said, but not like this.

“What we saw recently in the last eight weeks is unrelenting cascades of torrential rain that no monsoon has ever brought with it ever before,” she said.

The heavy rains are the latest in a series of catastrophes that Rehman said are exacerbated by climate change, including heatwaves, forest fires, and glacial lake outbursts. The damage reflects how poorer countries often pay the price for climate change largely caused by more industrialised nations. Since 1959, Pakistan is responsible for only 0.4 per cent of the world’s historic CO2 emissions. The US is responsible for 21.5 per cent, China for 16.5 per cent, and the EU 15 per cent.

“Climate knows no borders and its effects can be disproportionately felt,” Rehman said. “When you see low pressure systems coming from the Bay of Bengal, they hit us. So we’re on the front line of a global crisis.”

The National Disaster Management Authority said floods this summer have killed more than 1,136 people and injured 1,636 as well as damaged one million homes. At least 498,000 people in the country of 220 million are in relief camps after being displaced, it said. Many more displaced are believed to be living with relatives, friends, or outside.

International aid was starting to flow into Pakistan, and the military was helping distribute aid to remote areas and evacuate those who had lost their homes. Authorities were starting the long effort of rebuilding roads and restarting railways. The floods destroyed more than 150 bridges and numerous roads have been washed away, making rescue operations difficult.

In the south-eastern town of Shikar Pur, not far from the Indus River, Rehan Ali dug up bricks from the collapsed walls of his home, nearly completely destroyed by lashing storms and waters that raged through. His family’s possessions were strewn around outside.

The 24-year-old labourer said he cannot rebuild without Government help and can’t work now because of the turmoil. “I don’t even have anything to feed my family. I lost everything. I don’t know where to go. God help me,” he said.

Arif Ullah, an official at the Pakistan Meteorological Department, told the AP that more rains will continue to lash parts of Pakistan next month.

Prime Minister Shabaz Sharif on Monday said the rains so far have been the heaviest Pakistan has seen in three decades.

“I saw floodwater everywhere, wherever I went in recent days and even today,” Sharif said in the town of Charsadda in the north-east of the country. Some 180,000 people in the town have been evacuated after the Swat River overflowed and swamped nearby communities.

Sharif has said the Government would provide housing to all those who lost their homes.

But many of the displaced have lost not just homes, but also crops and businesses.

“I am sitting with my family in a tent, and how can I go out to work? Even if I go out in search of a job, who will give me any job as there is water everywhere,” asked Rehmat Ullah, a flood victim in Charsadda.
