- Global climate change will have profound a effect on precipitation world wide.
- Scientists anticipate that the amount of precipitation per year will increase, as the warmer the atmosphere becomes, the more water vapor it holds. However, they say that this increase will vary from region to region.
- At high latitudes levels of precipitation are expected to increase, while at low latitudes it is expected to decrease. Thus, the gap between areas with abundant water and areas with scarce water will worsen.
- Precipitation in the United States alone has increased between 5% and 10% since the turn of the century.
- The amount of precipitation being received in areas such as Africa and the Caribbean has decreased in recent years.
