Public health consequences of global climate change in the United States--some regions may suffer disproportionately

Climate Communication, Public Health, and Social Media: Examining the Role of Health Agencies in Addressing the Impacts of Climate Change on Human Health

The impacts of climate change on human health are a critical public health concern, with previous studies highlighting its clear effects on well-being. Understanding how state and territorial health agencies (STHAs) are addressing these emerging risks is important. This study conducted 26 in-depth interviews across the U.S. to explore the perceptions and communication strategies of STHA officials regarding climate change's impact on human health. Additionally, the study sought to identify the primary challenges faced by these officials to effectively communicate the impacts. Thematic analysis of the data revealed three major themes: community building and coalitions, climate denialism on social media, and misinformation about climate change and its effects on human health. These findings offer valuable insights for climate change and public health communication. The importance of the STHAs' development of technical and informational capacity to effectively communicate climate-related risks and threats is emphasized.

Climate change: the public health response

There is scientific consensus that the global climate is changing, with rising surface temperatures, melting ice and snow, rising sea levels, and increasing climate variability. These changes are expected to have substantial impacts on human health. There are known, effective public health responses for many of these impacts, but the scope, timeline, and complexity of climate change are unprecedented. We propose a public health approach to climate change, based on the essential public health services, that extends to both clinical and population health services and emphasizes the coordination of government agencies (federal, state, and local), academia, the private sector, and nongovernmental organizations.

Global climate change and children's health

There is a broad scientific consensus that the global climate is warming, the process is accelerating, and that human activities are very likely (>90% probability) the main cause. This warming will have effects on ecosystems and human health, many of them adverse. Children will experience both the direct and indirect effects of climate change. Actions taken by individuals, communities, businesses, and governments will affect the magnitude and rate of global climate change and resultant health impacts. This technical report reviews the nature of the global problem and anticipated health effects on children and supports the recommendations in the accompanying policy statement on climate change and children's health.

Climate change and mosquito-borne disease

Global atmospheric temperatures are presently in a warming phase that began 250--300 years ago. Speculations on the potential impact of continued warming on human health often focus on mosquito-borne diseases. Elementary models suggest that higher global temperatures will enhance their transmission rates and extend their geographic ranges. However, the histories of three such diseases--malaria, yellow fever, and dengue--reveal that climate has rarely been the principal determinant of their prevalence or range; human activities and their impact on local ecology have generally been much more significant. It is therefore inappropriate to use climate-based models to predict future prevalence.
