Global Warming Increases South Asian Monsoon Downpour Intensity = Increased Risk of Flooding

With the ongoing heat in Russia and the flooding in Pakistan (not to mention landslides in China) everyone's commenting on the connection with climate change, with the appropriate caveat that no single weather event can be linked with it but... Well, here's an interesting addition to those: Dot Earth points out a study from back in 2006 linking increased frequency and intensity of monsoonal rain with warming temps:

The frequency and intensity of rainstorms during India's monsoon season has risen significantly since 1950, in concert with global warming, scientists report. An Indian climate research team describes the trend in the journal Science and predicts that further warming is likely to raise the risk of floods. The pattern was found by analyzing rain-gauge measurements. Over all, the total rainfall in June-to-September monsoons across central India had not appreciably changed, but more rain came in sudden bursts and less in light showers, the scientists said. "A substantial increase in hazards related to heavy rain is expected over central India in the future," they added. (New York Times)

Wunderblog also explains (post- obligatory no single event commentary...), "A warming climate does load the dice in favor of extreme precipitation events. This occurs because more water vapor can evaporate into a warmer atmosphere, increasing the chances of heavy downpours."
