From another website...
"officials said at the current rate, the Global Mean temperature will rise
1.7 degrees Celsius over the next 100 years."
I still think it might be too soon for Chicken Little... :-)

This is one of the many health-related consequences of
global warming. I'm serious.

Mo. issues tick warning
By Tina Hesman Saey <tsaey@xxxxxxxxxxxxxxxxx>
ST. LOUIS POST-DISPATCH

Officials at the Missouri Department of Health and
Senior Services are
warning residents to be wary of ticks. A child in
northeastern Missouri died
May 23 of an infection with a tick-carried bacterium
called Ehrlichia
chaffeensis. That is one of three types of bacteria
that cause the illness
known as ehrlichiosis. All three types are found in
Missouri.
So far, the health department has confirmed 16 cases
of ehrlichiosis and is
investigating two other cases. On average, Missouri
has about 9 cases of the
diseases at this point during the year.
Cases of Rocky Mountain Spotted Fever have more than
doubled this year.
State health officials have confirmed 54 cases of
the illness this season.
In an average year, only 22 cases would have been
seen by this time.
Health officials have also had reports of 10 cases
of Lyme-like disease and
two cases of tularemia.
Symptoms of the illness usually resemble the flu
with body aches, tiredness,
and fever, said Joyce Berkowitz, infection control
practitioner at SSM
Cardinal Glennon Children's Hospital. Rocky Mountain
Spotted Fever usually
starts with a rash, but rashes appear in less than
half of people with
ehrlichiosis.
The hospital has seen only two possible cases of
tick-borne illnesses this
year. Advertisement
"We usually start seeing stuff when the kids get out
of school and are in
vacation mode," Berkowitz said.
Brian Allan, a biology graduate student at
Washington University, has been
tracking ticks for four years. It's too early in the
season to say if the
increase in diseases from tick bites are due to a
larger number of ticks.
In Illinois, the Department of Public Health has
had an increase in the
number ticks reported by veterinarians, doctors and
others, but people have
not fallen ill at a higher rate than usual.
The increase in human illness may be due to a
greater percentage of ticks
carrying disease, Allan said. The infection rate is
determined largely by
population fluctuations in animals that serve as
reservoirs for the
diseases.
For instance, a large number of infected
white-tailed deer last fall could
lead to an increase human disease now, he said.
White tailed deer carry
Ehrlichia chaffeensis. So Lonestar tick larvae could
have feasted on
infected deer last August or September, picking up
the infection. The ticks
over-winter and emerge as nymphs between May and
July. Ticks at the
nymph life stage are most likely to transmit disease
to people, because
nymphs are small and easy to miss and people often
don't feel the
ticks crawling on their skin, Allan said.
Nymphs take a blood meal, drop off the host and
over-winter, emerging as
adults the following April. Adult ticks may also
infect people, but are more
noticeable and account for only a small number of
infections with tick-borne
diseases, Allan said.
