Certain types of populations are more vulnerable than others: for example, outdoor workers, student athletes, and homeless people tend to be more exposed to extreme heat because they spend more time outdoors. Excessive heat is more likely to affect populations in northern latitudes where people are less prepared to cope with excessive temperatures.

The length of the annual longest dry spell is projected to increase in most areas, but these changes are small: less than two days in most areas. Extreme precipitation is projected to increase, with an average change of 5% to 15% in the precipitation falling on the wettest day of the year. Also shown are projections of the wettest day of the year (bottom left) and the annual longest consecutive dry day spell (bottom right). The warmest day of the year is projected to be 4☏ to 6☏ warmer in most areas. By the middle of this century, the coldest night of the year is projected to warm by 6☏ to 10☏ over most of the country, with slightly smaller changes in the south. These include the coldest night of the year (top left) and the hottest day of the year (top right). Projected changes in several climate variables for 2046-2065 with respect to the 1981-2000 average for the RCP6.0 scenario. However, adaptive responses, such as wider use of air conditioning, are expected to reduce the projected increases in death from extreme heat. ![]() These deaths will not be offset by the smaller reduction in cold-related deaths projected in the winter months. These changes will lead to an increase in heat-related deaths in the United States-reaching as much as thousands to tens of thousands of additional deaths each year by the end of the century during summer months. Warmer average temperatures will lead to hotter days and more frequent and longer heat waves. Certain populations, such as children, pregnant women, older adults, and people with low incomes, face increased risks see the section below on Populations of Concern. People in developing countries may be the most vulnerable to health risks globally, but climate change poses significant threats to health even in wealthy nations such as the United States. Impacts will vary based on a where a person lives, how sensitive they are to health threats, how much they are exposed to climate change impacts, and how well they and their community are able to adapt to change. The severity of these health risks will depend on the ability of public health and safety systems to address or prepare for these changing threats, as well as factors such as an individual's behavior, age, gender, and economic status. These impacts threaten our health by affecting the food we eat, the water we drink, the air we breathe, and the weather we experience. The impacts of climate change include warming temperatures, changes in precipitation, increases in the frequency or intensity of some extreme weather events, and rising sea levels. These groups include the poor, some communities of color, limited English-proficiency and immigrant groups, indigenous peoples, children and pregnant women, older adults, vulnerable occupational groups, people with disabilities, and people with medical conditions. Every American is vulnerable to the health impacts associated with climate change, but some populations will be especially affected.Climate change can affect human health in two main ways: first, by changing the severity or frequency of health problems that are already affected by climate or weather factors and second, by creating unprecedented or unanticipated health problems or health threats in places or times of the year where they have not previously occurred.Climate change is a significant threat to the health of the American people.Global Change Research Program produced a report that analyzed the impacts of global climate change on human health in the United States. ![]()
