Climate Change Impacts

  • Climate Change and Children's Health

    Children are often more vulnerable to the impacts of climate change. Learn more about climate change and children's health.

  • Air Quality

    Poor air quality harms the health of many Americans. Climate change can worsen air quality, such as by increasing wildfire smoke and airborne allergens. Learn more about climate change impacts on air quality.

  • Rapid Warming in the Arctic

    The Arctic is warming more than twice as fast as the rest of the planet. Warming temperatures, thawing permafrost, melting sea ice, and other impacts can affect communities, ecosystems, and economies. Learn more about climate impacts in the Arctic.

  • Climate Change and Indigenous Populations

    Tribes and Indigenous communities are disproportionately affected by climate change impacts. Read more about climate change and Indigenous populations.

The changing climate impacts society and ecosystems in a broad variety of ways. For example, climate change can alter rainfall, influence crop yields, affect human health, cause changes to forests and other ecosystems, and even impact our energy supply. Climate-related impacts are occurring across the country and over many sectors of our economy.

Explore the impacts of climate change on human health, by economic sector, or by state and region.
