Seeking Comments on Draft USGCRP Climate and Health Assessment

US Global Change Research Program

Public Comment Period Now Open!
April 7, 2015

Dear Colleague:
This message marks the official start of the 60-day public comment period of the U.S. Global Change Research Program's draft report, The Impacts of Climate Change on Human Health in the United States: A Scientific Assessment. The draft report assesses the observed and projected impacts of climate change on human health in the United States, with a particular focus on where impacts can be quantified.

This draft assessment was developed by the Interagency Group on Climate Change and Human Health, a USGCRP working group, as part of the sustained National Climate Assessment and as called for under the President’s Climate Action Plan.

Each chapter of the draft assessment summarizes the scientific literature on specific climate change-related health outcomes or exposures important to health.

Chapters include:

  • Climate Change and Human Health
  • Temperature-Related Death and Illness
  • Air Quality Impacts
  • Vectorborne Disease
  • Water-Related Illness
  • Food Safety, Nutrition, and Distribution
  • Extreme Weather
  • Mental Health and Well-Being
  • Climate-Health Risk Factors and Populations of Concern

The draft assessment and information on submitting comments are available at: All comments must be submitted to the website by 12:00pm EDT on June 8, 2015.

We appreciate your input and encourage you to share this with your colleagues.

Christopher P. Weaver
Acting Executive Director, U.S. Global Change Research Program

Program Description

It is anticipated that climate change will bring extreme weather events, rises in sea level, flooding, drought, and poor air quality. These environmental changes can directly and indirectly impact our health.

Extreme heat can increase risk for heat-related illnesses and degrade air quality, which causes problems for people with respiratory diseases such as asthma. Extreme cold and heat are associated with increased hospitalizations related to cardiovascular disease, and floods can increase exposure to various contaminants. The ways we adapt to climate change also has potential health effects. For example, increased use of air conditioning would require more electricity from power plants, which might increase air pollution.


climate change and the many collaborative research initiatives - NIEHS, Coordination, Federal, NIH - Mitigation and Adaptation, Population Vulnerability, Communication and Education, Methods and Models - Climate Change / Weather Variability

The NIEHS Climate Change and Human Health program funds research aimed at understanding the health impacts of climate change and how strategies used to adapt to or lessen climate change might affect health adversely. This research will help identify populations who are vulnerable to climate change, produce methods and models for studying climate change, and advance knowledge about how to best provide communication and education about risks tied to climate change. The program also plays a key role in facilitating the collaboration and coordination of both the research program and other activities related to climate change taking place within NIEHS and across NIH and other federal agencies.

Grantees currently funded by NIEHS are examining risk factors associated with increased vulnerability to health impacts of global climate change, covering a variety of topics, including how heat and air pollution interact to influence population vulnerability among elderly adults, children and pregnant women, and other vulnerable populations (such as Native Americans); the health impacts of climate change-related increases in forest fires and pollen exposure; and the health impacts of adaptive response to climate change (such as home weatherization and increased use of air conditioning) as well as co-benefits of mitigation of greenhouse gasses for addressing climate change. Other NIEHS-funded grantees are developing new methodological approaches to predict health vulnerabilities to climate change.
