The results are contrary to the general notion that global warming or increased summer temperature is responsible for extreme summer monsoon rainfall events. experienced a change in extreme rainfall with increasing temperature, while other grids witnessed a decrease or no significant change in rainfall with increased temperature. A study carried out in Brazil revealed that there was a decrease in extreme rainfall with increasing temperature. “The new generation climate model and historical simulations tend to over-estimate the association between extreme rainfall events and temperature. However, the model simulation of Indian rainfall extremes tends to “overestimate the changes in both mean and extreme precipitation”.
