Precipitation is a very important part of climate. Precipitation is the solid, liquid, or gaseous water that falls from the atmosphere to Earth's surface. This includes snow, sleet, hail, rain, and even mist. Changes in the amount of precipitation falling to Earth affect our lives in many ways. Daily human activities, business and industry, agriculture, and the environment all require water. Much of Earth's water ultimately
comes from precipitation. Too little precipitation can result in dry soil, shallow streams, and shortages of municipal water supplies.
However, too much precipitation can also have a negative impact on human activities, business and industry, agriculture, and the environment. For example, too much rain or snowmelt (water from melted snow) at one time can lead to flooding. Living organisms, including crops, can drown in floodwaters.
Homes, businesses, even land can be washed away.

That is to say, they have been watching changes in the amount of precipitation falling to Earth. In the last 100 years, precipitation has increased by an average of about 1% over all the land surfaces on Earth. Across the United States, alone, precipitation has increased by an average of about 5% in the last 100 years. Note that this is an average. Some areas of the United States have experienced as much as a 20% increase in precipitation over the last 100 years (see figure above). While other areas have experienced a 20% decrease in precipitation.
