All Americans, at some point in their lives, are vulnerable to the impacts of climate change. Some people are more affected by climate change than others because of factors like where they live; their age, health, income, and occupation; and how they go about their day-to-day lives. Understanding the threats that climate change poses to human health can help us work together to lower risks and be prepared. EPA has developed communication materials that summarize key points from the U.S. Climate and Health Assessment for eight different populations that are disproportionately affected by climate change impacts. The agency is providing these materials for use and modification for anyone seeking to communicate the health impacts of climate change to a range of audiences.
