Before you do anything else, you might want to read David Leonhardt’s N.Y. Times piece explaining the connection of global warming to extreme rainfall…



Precipitation can have wide-ranging effects on human well-being and ecosystems. Rainfall, snowfall, and the timing of snowmelt can all affect the amount of surface water and groundwater available for drinking, irrigation, and industry. They also influence river flooding and can determine what types of animals and plants (including crops) can survive in a particular place. Changes in precipitation can disrupt a wide range of natural processes, particularly if these changes occur more quickly than plant and animal species can adapt. (-Source EPA)

Current climate models indicate that rising temperatures will intensify the Earth’s water cycle, increasing evaporation. Increased evaporation will result in more frequent and intense storms, but will also contribute to drying over some land areas. As a result, storm-affected areas are likely to experience increases in precipitation and increased risk of flooding, while areas located far away from storm tracks are likely to experience less precipitation and increased risk of drought.

Extreme Precipitation Increase

Global warming leads to an increase in both ocean evaporation into the atmosphere and the amount of water vapor the atmosphere can hold when fully saturated. Warmer air, holding more moisture creates conditions more favorable…


Fewer rainy days leading to earlier spring in northern climes
