One-third of Pakistan is underwater with over 1100 dead. Global warming is sharply increasing the likelihood of extreme rain in South Asia, home to a quarter of humanity. The South Asian summer monsoon is part of a regional weather pattern. Basically, winds tend to blow from the southwest from June through September. That onshore breeze brings wet weather. Rising temperatures mean that water evaporates much faster out at sea. And, a warmer atmosphere can hold more moisture. So, monsoons risk bringing way too much rain. This monsoon season, rainfall in Pakistan has been nearly three times the national average of the past 30 years. In Sindh Province, bordering the Arabian Sea to the south, rainfall is nearly five times the average.
