are exposed to high temperature extremes eventually suffer from
heat stress, dehydration, respiratory distress, and occasionally
heat stroke or cardiac malfunction. Luckily, heat waves in the Great
Lakes region are still relatively rare. Although the HadCM2 and
CGCM1 models suggests significant increases in the number of days
above 90°F. Also, interannual variability may decrease
so cool summers may not occur as frequently as they do now. Other
impacts from short-term, extreme weather events such as floods,
tornadoes, and blizzards, may also increase in frequency in the
Great Lakes region especially heavy precipitation events.
associated respiratory disease has not been well studied in the
Great Lakes region. Results suggest that air pollutants are but
some of many factors involved in the etiology of respiratory diseases.
The GCM output from the CGCM1 and HadCM2 models suggests that the
number of days with synoptic patterns that are conducive to high
ozone will increase by the end of this century across much of the
Great Lakes region.

Change & Tourism
Lakes region´s significant natural beauty and cultural features
combine to attract tourists from all over the Midwest. Recreation
and tourism activities that were looked at for this study include:
fishing; snowmobiling; skiing; pleasure boating; leaf peeping; bird
watching; hiking; sightseeing (driving); hunting; gambling; and
stresses on the rural landscape are already significant. Climate
change in the form of increased temperatures and anomalous severe
weather events will serve to further challenge a landscape that
is already in the process of profound change.
