A study by IIT Gandhinagar has linked Indus Valley Civilization’s collapse to four severe droughts lasting for 88-164 years between 4,400 and 3,400 years ago with up to 20% reduction in rainfall, reduced river discharge of over 12%, together with 0.5 degree C warming

The Ganga River has been through unprecedented drying for 30 years between 1991 and 2020 in the last 1,300 years (700 to 2012). The drying seen during 1991-2020 is 76% more intense than the last severe drought that occurred in the 16th Century — between 1501 and 1530. The lastest 30-year period stands out as the driest period not only because of the number of drought years but also because the drought prolonged for a few years without a break

Storms interacting with Chennai’s urban environment consistently deposited their peak rainfall 16-20 km inland, whereas storms over rural areas peaked closer to the coast, within 8-12 km. Urbanisation thus plays a decisive role in altering the spatial distribution of rainfall, particularly by shifting the zone of heaviest precipitation farther inland
