Indian summer monsoon

The Indian summer monsoon rainfall between June and September critically affects India’s agriculture and economy. It is the primary delivery mechanism for fresh water in the Indian subcontinent. Global warming tends to strengthen the monsoon since warmer air can carry more water. Air pollution and land-use that increases the reflection of sunlight tend to weaken it. The Indian summer monsoon could become more and more unpredictable and in the worst case start to chaotically change between an active and a weak phase within a few years.
