Study confirms link between
carbon dioxide and tree growth
by Barry Cohen
Studies conducted at the
University's Biological Station in
Pellston, Mich., yielded prelimi-
nafy evidence that global warming
will cause major changes in forest
The on-going study simulated
the effect of increased carbon diox-
ide concentrations on the growth of
white pine, red maple, and aspen
After being exposed to concen-
trations of carbon dioxide predicted
to be present in the year 2050, the
trees' growth rate was higher than
that of trees exposed to present car-
bon dioxide concentrations. Donald
Zak, assistant professor of natural
resources, said, "It is pretty clear
carbon dioxide levels are increasing,
along with nitrous oxide and
James Teeri, director of the sta-
tion and professor of biology, said
the purpose of the study was to
"address the question of whether or
not the rise in carbon dioxide by it-
self will have any effect on growth
The increased concentration of
carbon dioxide had a two-fold effect
upon the trees: accelerated growth
and a delayed change in leaf color.
The study was the first in the
country to test increased levels of
carbon dioxide on indigenous trees
grown in nutrient-poor soil. After
one summer of growth, the aspens
exposed to higher levels of carbon
dioxide weighed thirty percent
more than the aspens exposed to
present levels. The white pine and
red maple weighed twenty percent
more than their counterparts.
Teeri said the results "strongly
suggest that ecosystems will be dif-
ferent, that increased levels of car-
bon dioxide will alter plant
growth." He cautioned against
drawing broad conclusions from the
evidence. But he said, "We are cer-
tain the forest in northern Michigan
will look significantly different
100 years from now."
A potential danger in the study's
findings is that an increased concen-
tration of carbon dioxide will alter
the sensitively balanced ecosystem.
Any changes with the growth rate
of trees will have repercussions on
all of the other elements in the
Fred Verner, School of Natural
Resources sophomore and member
of ENACT, said, "This study con-
firms that changes will occur. -But
it gives no indication what (the
changes) will do to the diversity or
balance of the ecosystem."
Zak said since people use so many
forest products, "It is important to
understand how global change will
effect forest ecosystems."

allegations is realistic, the revised
policy has measures that protect
against random accusations.
- "If the allegations cannot be
substantiated ... no disciplinary ac-
tion is taken against the accused,"
Whitaker said. "The issue here is to
make sure that people who have
complaints come forward."

not provide for a fair basis for hear-
ings of sexual harassment cases. For

importance of having a solid,

"Our goal is to get a policy in

University community," Whitaker
said. "We need the policy in order to

its $62 face value.
Other students view the games as
an opportunity to profit in a much
different sense. LSA senior Ron
Dolak uses the games as an excuse to
throw parties. Dolak estimates he
used roughly 280 cups during the
Notre Dame game. When it comes to
the game itself, he attests to the old
argument that any house, as long as
it has a television, is really the
"best seat in the house."
While some choose not to go,
others simply cannot go. LSA senior
Michael Goldburg, for example, has
unwillfully missed the first two
home games this year. During the
Florida State loss, Goldburg found
himself "playing host." He had a
visitor from out of town, and they
decided that cruising Ann Arbor's
streets would prove more reward-
ing than subjecting themselves to
the struggle to locate a ticket.
Missing the games, whether de-
liberately or not, does not seem all
that common, said Brian Klemz, as-
sistant ticket manager at the
Athletic Ticket Office. "Sales are
better this year than in the last few
years," he said.
The Notre Dame game lured the
fifth largest crowd in Michigan
Stadium history, and the second
home game generated an attendance
of 106,145, the fourth largest crowd

Tom Butts, director of the

for violating the idea of capitalism.

touted in Eastern Europe we are try-°

Counselors are there for one an-
other when they grow discouraged
or need reassurance. For some this
makes the counseling experience
special. "I love working there," said
Brian, a new counselor. "I've never
had that kind of network or support
system on a job."
The greatest rewards about peer
counseling, they say, comes from
"I feel really good about what
I'm doing," Brian said. "How often
do you get a chance to help some-
body that you don't even know?"
Jabeen remembers all the callers
who really appreciated the service.
"Sometimes you'll be on the phone
for an hour and after they'll say
'Thanks alot, you really helped
me."' she said. "It gives you such a
sense of fulfillment. You helped
someone for the time being and that
makes it all worth it."
