Rising temperatures may trigger a dangerous increase in 'hydroclimatic whiplash' in rivers that would make traditional approaches to flood and drought planning insufficient. According to the Guardian, rivers will experience increasingly rapid transitions between heavy downpours and long dry spells — called hydroclimatic whiplash events — because a warmer atmosphere holds more moisture, intensifying rainfall extremes. Nature.com reported that the hydrological cycle is expected to intensify with global warming, which likely increases the intensity of extreme precipitation events and the risk of flooding. Changes in extreme precipitation and flood intensities for the end of the twenty-first century vary with spatial and seasonal water availability, according to Nature.com. The intensification of extreme precipitation and flood events increases as water availability increases from dry to wet regions, and also increases with the seasonal cycle of water availability, Nature.com reported.
