Floods, Droughts, and Extreme Weather Events

As the climate changes, extreme weather events will occur more frequently.  Examples include droughts, which are caused by an extreme lack of precipitation, and floods, which are caused by an extreme abundance of precipitation.   These extreme weather events will impact health in many ways.  For example, c hanges in water runoff patterns will alter our food and water supplies.  In addition, changes in the weather and water runoff patterns will influence the spread of vector-borne diseases.  Floods can devastate our communities and result in drownings, infections, displacement from one's home, and long-lasting mental health effects.
