IISC research tells:

• Indian monsoon rainfall increased from the last glacial maximum to the present

How?

• Increasing temperatures result in increase in water vapour in the atmosphere, which causes an increase in the quantum of rainfall. 
• Concentration of carbon dioxide in the atmosphere going up, resulting in more water vapour, rainfall is expected to increase in the next 100 years.
