"The hydrological cycle is ultimately driven by the sun's energy, the amount of heat and water that's in the atmosphere. With global climate change we've trapped more heat in the lower atmosphere and the cycling of water in the atmosphere and on earth will be exacerbated, that means it will be increased, accelerated.
"For Minnesota's rivers, and the environments around the rivers, this means that we can expect more extreme precipitation events, more violent storms, earlier flooding, and some of the water resources that naturally protect our rivers and even out their flows, things like the prairie potholes of western Minnesota and wetlands throughout the state, which help to even out flows into a river. Unfortunately scientists think that with the increased evaporation that we're likely to see in the hotter summers, the Kansas-like summers, those areas may dry up and so we won't have those resources as wildlife habitat and we won't have them to control some of the floodwaters heading toward our rivers."
