Did you know that changes in the Earth’s climate can affect things such as public health, agriculture, water supplies, energy production and land development? Indeed, changes in climate affect the average weather conditions to which we are accustomed, and these changes may result in multiple threats to human health and welfare. For example, warmer average temperatures will likely lead to hotter days and more frequent and longer heat waves, which could increase the number of heat-related illnesses and deaths. Increases in the frequency or severity of extreme weather events, such as storms, could increase the risk of dangerous flooding, high winds, and other direct threats to people and property. Overall, the nature and extent of these effects from climate change, and whether they will be harmful or beneficial, will vary regionally and over time.
