The mission of the NIEHS is to reduce the burden of human illness and disability,
by understanding how the environment influences the development and progression
of human disease.

Global Public Health Leaders Call for Action
Climate change is one of the
most serious public health
threats facing our nation.
Yet few Americans are aware
of the very real consequences
of climate change on the
health of our communities,
our families and our children.

Executive Director
American Public Health Association

Empirical research links between climate
and adverse health outcomes
•
2006 California Heat Wave: 16,166 excess emergency department visits
and 1,182 excess hospitalizations (Knowlton et.al. 2009, Environmental Health
Perspectives)
•
Under three different climate change scenarios for 2081 -2100 and in the
absence of adaptation, the city of Chicago could experience between 166 and
2,217 excess deaths per year attributable to heat waves, based on
estimates from seven global climate models (Peng et al., 2011, Environmental Health
Perspectives)
•
Climate change could cause an increase in regional summer ozonerelated asthma emergency department visits for children aged 0-17 years
of 7.3% across New York City by 2020. (Sheffield et. al., 2011, American Journal of
Preventive Medicine)
•
Recent warming by latitude associated with increased length of ragweed
pollen season in central North America (Ziska et.al., 2011, Proceedings of the National
Academy of Sciences)

Climate Change: A Human Health Perspective
What you will do: Read, Identify, Map
Learning Outcomes:
•Participants will be able to describe potential
impacts of climate change on human health.
•Participants will be able to organize
information into a visual to assist with
understanding the complexities of the climate
change-health effect system.
•Participants will be able to describe the health
co-benefits of climate change adaptation.

Directions
• Change in climate  Environmental impacts 
environmental hazards  health effects
Change in climate: Increase in temperature
Environmental Impact: Decrease in cloud cover
Environmental Hazard: Increase in ultraviolet radiation
Health Effect: Increase in incidence of skin cancer
(Note: that health effects are population-specific, not individual-specific.)
• Changes in climate: Changes in precipitation,
temperature, weather patterns

What next...some ideas
Alliance for Climate Education (ACE) funds student led climate adaptation
programs.
Starting an Environmental Club at school.
Bringing in guest speakers – state and county officials working on climate
adaptation and mitigation strategies, university researchers.
Resource conservation projects in your school.
Develop a heat-management plan for your school.
Anti-idling campaign for your school.
Others…..
