Marquette, MI--This week the
Committee on Environment and Natural
Resources, National Science and
Technology Council, released a 271-page
report on global climate change
entitled: Scientific Assessment of
the Effects of Global Change on the
United States.
Climate change concerns for Upper
Peninsula residents, as described in the
national scientific report, include high
and low water levels in the Great Lakes,
increased frequency of high
precipitation events "in most areas" of
the country, increases in diseases
throughout North America, lack of public
preparedness, and challenges in the
American health care system. |

Sea level rise is not an issue for the
Great Lakes, according to the report,
but "damaging and disruptive" high and
low water levels are described.
In the Great Lakes where sea level
rise is not a concern, both
extremely high and low water levels
resulting from changes in the
hydrologic cycle have been damaging
and disruptive to shoreline
communities (Nicholls et al., 2007).
High lake water levels increase
storm surge flooding, accelerate
shoreline erosion, and damage
industrial and commercial
infrastructure located on the shore.
Conversely, low lake water levels
can pose problems for navigation,
expose intake/discharge pipes for
electrical utilities and municipal
water treatment plants, and cause
unpleasant odors (page 171).

Another concern is the projection by
scientists of increases in "heavy
precipitation event frequency over most
areas," as detailed on page 175:
In addition, the
IPCC [Intergovernmental Panel on
Climate Change] projects a
very likely
increase in heavy precipitation
event frequency over most areas.
Heavy precipitation events are
associated with increased risk of
floods as well as infectious,
respiratory, and skin diseases (IPCC,
2007b).
The report cites 2008 research showing
"that increasing temperatures may result
in increased incidence of disease" (page
183). The report states that "research
also suggests that climate
variables...may be an important driver
for influenza outbreaks" (page 183).
The report warns of increased incidences
of water- and food-borne diseases.
Reaction to inhalant allergens is a
common concern for U.P. residents, and
pollens are "likely to increase,"
according to the scientific report:
The IPCC concluded that pollens are
likely
to increase with elevated
temperature and atmospheric CO2
concentrations in North America
(Field et al., 2007). Moreover,
warming and climate extremes are
likely
to increase pollen and ozone levels,
both of which have the potential
to exacerbate symptoms in people
with respiratory illness (page 186).
The report states that "climate change
has caused an earlier onset of the
spring pollen season in North
America..." (page 186). |

According to the scientists, the
American public will benefit from
disaster preparedness education, among
other recommendations.
Surveys find that the public is
either not aware of the appropriate
preventive actions or incorrectly
assesses the extent of their
personal risk (page 178).
Vulnerability to weather disasters
depends on the attributes of the
people at risk (including where they
live, age, income, education, and
disability) and on broader social
and environmental factors (level of
disaster preparedness, health sector
responses, and environmental
degradation) (page 182).

Continued trouble in the American health
care system is suggested in the national
report on page 178:
Finally, climate change is very
likely to accentuate the disparities
already evident in the American
health care system. Many of the
expected health effects are likely
to fall disproportionately on the
poor, the elderly, the disabled, and
the uninsured. The most important
adaptation to ameliorate health
effects from climate change is to
support and maintain the United
States’ public health
infrastructure.
In summary, the May report,
Scientific Assessment of the Effects of
Global Change on the United States,
is loaded with detailed information for
all Americans about global climate
change in an easy-to-read and study PDF
format.

According to the May 2008 report, the
"Key conclusions...for North America
include:"
• Increased deaths, injuries,
infectious diseases, and
stress-related disorders and
other adverse
effects associated with social
disruption, migration, and loss
of place from more frequent
extreme weather.
• Increased frequency and
severity of heat waves leading
to more illness and death,
particularly
among the young, elderly, frail,
poor, and outdoor workers and
athletes.
• Expanded ranges of vector- and
tick-borne diseases in North
America but with modulation
by public health measures and
other factors. (page
177)

The public message (for me) of the
National Science and Technology Council
report,
Scientific Assessment of the Effects
of Global Change on the United States,
is this:
Learn, adjust, adapt, prepare.
