Announcing the results on their website yesterday, NWF climate scientist Dr. Amanda Staudt explained:“Global warming is partly to blame for these heavy rainfall events. Warmer air simply can hold more moisture, so heavier precipitation is expected in the years to come.”According to the report itself [PDF]:“As the climate continues to warm, the atmosphere will be able to hold more water. With more moisture in the air, the trend towards increasingly intense precipitation events will continue.
