Climate and Extreme Weather Conditions

Climate and extreme weather conditions pose current and increasing threats to human health and are considered by the leading public health organizations as the "single biggest health threat facing humanity”. As the climate continues to warm, the risks to human health will grow, exacerbating existing health threats and creating new public health challenges. In addition, according to the National Climate Assessment, the health impacts of climate and extreme weather conditions are not felt equally, and some populations are at higher risk than others. With this in mind, organizations across the country are committed to addressing these key issues. For more than 200 years, men and women have served in what is today called the Commissioned Corps of the US Public Health Service (USPHS), an agency responsible for protecting our nation’s health in all 50 states and US territories. The National Park Service (NPS) Office of Public Health leads dozens of members of the US Public Health Service Commissioned Corps to support public health imperatives at national parks across the country—a partnership that has lasted for more than a century to help keep people in parks safe and health.
