“Climate change poses risks to human health through many pathways, some more obvious than others. Rising greenhouse-gas concentrations, driven by human activities, result in increases in temperature, changes in precipitation, increases in the frequency and intensity of some extreme weather events, and rising sea levels. These climate-change impacts endanger our health by affecting our food and water sources, the air we breathe, the weather we experience, and our interactions with the built and natural environments. As the climate continues to change, the climate-related risks to human health will continue to grow. Today, building on the Third National Climate Assessment issued in May 2014, the Administration released a new report summarizing the growing understanding of how climate change is directly and indirectly affecting human health.  The report, The Impacts of Climate Change on Human Health in the United States: A Scientific Assessment, finds that “every American is vulnerable to the health impacts associated with climate change.” Drawing from decades of advances in the science of climate change and its influences on ecosystems and human society, the report strengthens our understanding of the significant threat that climate change poses to the health of all Americans and highlights factors that make some individuals and communities particularly vulnerable.”
