What is Global Warming?
  • A premise that the environment is increasing in
    overall air and water temperature.
  • If this trend is not interrupted or challenged,
    life on earth will be dynamically effected.
  • A quantifiable set of environmental results that
    are in addition to any normal changes in climate.
  • The effects of global warming can be
    catastrophic.
  • Industrial growth has negatively effected our
    environment by a cycle of harmful processes that
    can increase the damage to our ecosystem.

    warming? Retrieved on January 16 from

What is the most significant cause of global
warming?
  • The primary cause of global warming is Carbon
    Dioxide emissions. Eight billion tons of CO2
    entered the air last year. Currently 40 percent
    of all CO2 emissions are caused by power plants.
    These burn coal, natural gas and diesel fuel.
  • 33 percent of all CO2 is the product of cars and
    trucks with internal combustion engines burning
    fossil fuels.
  • 3.5 percent of CO2 emissions are released from
    aircraft. Jets and other aircraft deliver their
    pollutants directly into the troposphere.

What is the Greenhouse Effect?
  • The greenhouse effect is what happens when heat
    is trapped and then increases as more heat
    radiation is added.
  • It occurs when solar radiation bounces off or is
    radiated from the earth. Instead of passing
    through our atmosphere and into space, it is
    absorbed by extraneous gases and particles.
  • These gases absorb heat and radiate it in all
    directions, including the surface of the earth.
    The process repeats itself, until we have a
    global version of a car with the windows rolled
    up parked in the noonday sun.

Health Effects of Global Warming
  • In 1861, natural philosopher John Tyndall
    predicted that emissions of carbon dioxide would
    trap the radiative energy of the sun within the
    earths atmosphere and raise surface
    temperatures.
  • Recent data of several international consortia
    show global warming is accelerating at a rate far
    greater than predicted a century ago, due in
    large part to combustion of fossil fuels.
  • Global warming has emerged as a public health
    challenge requiring serious, concerted action.
  • The health care community can advocate policies
    that wean us from fossil fuels and mitigate the
    extent of human-induced climate change.

    health implications of global warming. JAMA,

Health Effects of Global Warming
  • Epidemiologists are looking at the potential
    influence of global warming and other climate
    changes on human health.
  • Research has shown evidence of a link between
    climate and microbial foodborne illnesses,
    including salmonella food poisoning.
  • Links have been found between latitudinal
    gradients in the amount of foodborne and
    diarrheal illnesses, changing disease patterns
    during El Nino warmings, and connections between
    weather disturbances and waterborne and foodborne
    illnesses.

health effects of environmental change, JAMA,
296(8), 913-914.

Health Effects of Global Warming
  • Researchers predict a 16 to 28 percent increase
    in person-months of exposure to malaria in Africa
    by 2100.
  • Studies estimate that future heat waves in Europe
    and North America will become more intense, more
    frequent, and longer lasting in the second half
    of the 21st century.
  • The population has exceed the earths carrying
    capacity, resulting in a whole range of problems
    including Global climate change, stratospheric
    ozone depletion, extinction of species, fresh
    water shortages.

What Can We Do About Global Warming?
  • Renewable energy standards
  • To ensure healthy air and a stable climate for
    our children and grandchildren, we must make
    responsible decisions about our energy sources.
  • Practical solutions
  • Renewable electricity standards have been enacted
    in 28 states and the District of Columbia. This
    commitment will have a significant impact on CO2
    emissions.
  • By 2025, state standards will reduce total CO2
    emissions by more than 183 million metric tons
    (MMT), the equivalent of taking 30 million cars
    off the road or planting a forest large enough to
    cover the state of Washington.

    warning. Retrieved on January 15, 2010 from

National Electricity Standards
  • Greater benefits could be achieved if Congress
    adopted a national standard for renewable
    electricity.
  • The 20 percent national standard could reduce
    growth in CO2 emissions from power plants by 63
    percent by the year 2020. This is equivalent to
    taking 36.4 million cars off the road.
  • The U.S. is only five percent of the worlds
    population, and produces nearly 25 percent of
    annual global heat-trapping emissions.
    Electricity generation accounts for one-third of
    these emissions. Renewable electricity standards
    offers an affordable climate solution with a
    proven track record.

Challenges for Climate Change and Health
  • Challenges for future climate change and effects
    on health include
  • Climate change science
  • Temperature-related morbidity and mortality
  • Health effects of extreme weather events
  • Water-related infectious diseases
  • Sea-level rise

    climate change and health Challenges for future
    practitioners. JAMA, 287(17), 2283-2284.
