Why do you think people choose to live in places that get flooded?
Pakistan's population is a bit over 230 million now (or maybe even 240 million). It was around 45 million in 1960 (not including Bangladesh). It was around 23 million in 1900 (not including the rest of British India).
The numbers vary a bit depending on source but the overall trend is unmistakable.
This increase is not due to "Climate Change" but to increases in public health (cleaner water, better sewers/latrines, soap, plumbing=easier hand washing, cleaner food, vaccinations) and available food (many, many more calories + vitamins).
If the Pakistanis choose to spend that wealth increase on a population growth instead of increase in personal wealth, well, that is not our fault. Perhaps they made the right choice, perhaps not. It's up to them.
Sorry, not to be snarky, here is the "Background" part of the wiki article :
"The minister of climate change of Pakistan, Sherry Rehman, said that the provinces of Sindh and Balochistan had received more rainfall than the August average, with 784% and 500% more, respectively.[9][10] Higher than average monsoon rains were also recorded in India and Bangladesh.[11] The Indian Ocean is one of the fastest warming oceans in the world, warming by an average of 1 °C (1.8 °F) (while worldwide temperatures are now at 1.2 °C (2.2 °F) above pre-industrial temperatures, oceans in general are at around 0.7 °C (1.3 °F)).[11] The rise in sea surface temperatures is believed to increase monsoon rainfall.[12][11] In addition, southern Pakistan experienced back-to-back heat waves in May and June, which were record-setting and themselves made more likely by climate change.[13][14] These created a strong thermal low that brought heavier rains than usual.[12][13] The heatwaves also triggered glacial flooding in Gilgit-Baltistan.[14]
Pakistan contributes less than 1% of global greenhouse gas emissions, but is one of the places most vulnerable to climate change.[15][16] A study by an international team of climate scientists says that global heating made the flooding up to 50% worse and future floods more likely.[17] However, some of the contributors to the severity of the flooding are local to the country. Deforestation in Pakistan has also been a factor worsening the floods"
So much larger than usual rainfall is the problem - they had record flooding - meaning bigger than ever recorded, right?
I don't understand why you are talking about public health like that had an impact in the amount of water that was covering more land than ever?
It not relevant to the comment we're replying to, which is arguing that this problem is not related to climate change and quoted this wikipedia article - is it?
