Experts say Pakistan's devastating floods are a warning to the world about the dangers of climate change.
A climate scientist has told the BBC that such disruptive rains will not only affect the poor but also wreak havoc in any country in the world.
Every day thousands of people have to be rescued from the flood waters.
And the humanitarian cost is clear as ministers warn of a food crisis after floods wash away half the country's grain.
There is a sense of injustice in Pakistan.
Why is Pakistan at risk?
Pakistan emits only one percent of the greenhouse gases that warm the earth, but due to its geography, it is highly vulnerable to climate change.
Unimaginable crisis in Pakistan, one third of the country under water
More than 1,000 people died in the monsoon devastation in Pakistan
"One-third of Pakistan is now under water, which is a different range or trend than we've seen before," Climate Minister Sherry Rehman said this week.
Pakistan is located in a place on earth where two-tiered weather systems are affected.
One system may bring high temperatures and drought around March, while the other brings monsoon rains.
A large population of Pakistan lives around the Indus River. Monsoon rains can cause massive floods in this river.
Climate change
The scientific link between climate change and extreme monsoons is simple.
Global warming increases the temperature of land and oceans, which increases evaporation.
Warm air carries more water vapor which causes more rain to fall.
Scientists predict an increase in average rainfall during the Indian monsoon, says Anya Katzenberger of the Potsdam Institute for Climate Impact Research.
But there is another factor that makes Pakistan more vulnerable to climate change: its glaciers.
