Carbon
dioxide
threatens
climate
BY VERA SONGWE
Although the greenhouse effect is
a natural phenomenon, the presence
of carbon dioxide in the atmosphere
only serves to hasten abnormal tem-
perature swings, a University pro-
fessor said Friday.
Prof. Don Portman of the Atmo-
spheric and Oceanic Science Depart-
ment said there has been an ex-
ponential increase in carbon dioxide
emissions due to the burning of fos-
sil fuels and cement by industries.
Portman addressed a crowd of
about 150 people at Angell Hall
Auditorium B Friday evening during
the Astronomy Department's "Visi-
tor's Night."
The greenhouse effect has never
been doubted, Portman said. When
the sun's rays strike the earth they'
warm the surface, which then gives
off heat in the form of infrared radia-
tion.
But atmospheric carbon dioxide,
- water vapor, and some other gases
absorb the infrared radiation and do
not allow it to pass undeterred
through the atmosphere to space. As
a result, the earth's temperatures
steadily inch upward. Because the
atmosphere traps the heat and warms
the earth in a manner analogous to
the glass panels of a greenhouse,
this phenomenon is called the
greenhouse effect.
While an increase in carbon diox-
ide is an issue to reckon with, the
most prevalent greenhouse gas is
water vapor - given off by the
evaporation of the oceans - and the
presence of chlorofluorocarbons in
the atmosphere.
Portman said the best way to be-
gin dealing with the problem would
be to start cutting down the amount
of carbon dioxide in the atmosphere.
"It is easier and less dangerous to
move to another source of energy,"
said Astronomy Prof. Elste Gunther,
organizer of the evening. "Most
people don't know the amount of
gas emitted into the atmosphere by
fossil fuel plants."
He said America is almost ready
for the solar age, and even though it
entails a lot of money, the end result
will be well worth the expense.

Group vows
to oppose
arraignments
BY RYAN TUTAK
More than 120 University and
Ann Arbor community members
rallied on the Diag Friday to protest
warrants issued for the arrest of four
University students. The students,
who had been protesting outside the
inauguration of University President
James Duderstadt on Oct. 6, will be
arraigned today.
LSA senior Rollie Hudson and
Rackham graduate student Sandra
Steingraber are being charged with
assault and battery of a police officer
and disturbing the peace. LSA senior
Cale Southworth is being charged
with assault and battery of a police
officer. Rackham graduate student
Michael Fischer is being charged
with disturbing the peace.
All four are Daily staff members.
They are scheduled to be arraigned
at 1:30 p.m. today in 15th District
Court at Ann Arbor City Hall.
Speakers at Friday's rally de-
manded that Duderstadt pressure the
Ann Arbor police to drop the charges
and to repeal several University
policies that limit the range of
protest on campus.
"We have the potential to build a
movement that will win our imme-
diate demands of dropping the
charges and our longer term goal of
eliminating the deputization of cam-
pus security, removing the protest
policy... and winning student and
worker control of running this insti-
tution," said Judy Levy, bargaining
chair for the American Federation of
State, County, and Municipal Em-
ployees.
Physics Prof. Dan Axelrod criti-
cized Duderstadt for protecting the
free speech of University community
members who support his ideals -!
including military research - while
condemning and trying to silence
those who oppose it.
"The University security guards
attack the most active and socially
conscious people on this campus,"
he said. "But administrators do not
speak of the people who will be at-
tacked and poisoned by nerve gases
studied here under contract from the
Army."
. Duderstadt was unavailable for
comment last night, but he had said
in the University Record that "it's a
tragedy when protest gets out of
hand and leads to confrontation."
Steingraber and Southworth en-
couraged people to support the ar-
rested students at today's arraign-
ment.
Fischer, Hudson, and Southworth
had been arrested during the inaugu-
ration protest but were released three
hours later without bond. Stein-
graber was hospitalized for a head
injury sustained during the protest.
The four were among 30
protesters holding a guerilla theater
mocking Duderstadt on the steps of
Hill Auditorium during the
inauguration. The Ann Arbor Police
had arrested Hudson when he and
about 15 protesters tried to enter ti .
closed ceremonies guarded by Ann.
Arbor police and campus security,
officers.

-Buenas Noches Ann Arbor!
Gooood Evening Ann Arbor! Stu-
dent-run WCBN-FM (88.3) has
launched two new weekly radio pro-
grams aimed at informing and enter-
taining the Hispanic-American
community or anyone interested in
Latin America.
Both programs, designed to ac-
quaint listeners with Latino music
and news, are broadcast in English.
"El Mundo Latino," hosted by
public health graduate student Luis
Vazquez, features news, interviews,
and some local events. In his pro-
gram this term, Vazquez has inter-
viewed a local expert on Puerto Ri-
can political prisoners and a student
who volunteered in Nicaragua
through AAMISTAD.
Future programs will include in-
terviews with Latin American artists
visiting Ann Arbor and people who
have recently visited the region,
Vazquez said. In addition, he reads
news reports about Latin America.
"The news that I read is not available
anywhere else on the dial," Vazquez
said.
And for Latin American music,
listeners can now turn to LSA senior
Will Pflaum's "Radio Caliente" (Hot
Radio). American listeners will be
surprised to find out that rock is
alive and well in Latin America,
Pflaum said. "Rock is not anymore
the sole American cultural domain,"
he said. "(Argentinian) Charlie Gar-
cia is one of the best pop musicians
in the world."
The program is designed to show
the universal nature of music, he
said. "Music doesn't have a country,
it violates borders, it doesn't have
colors, and it doesn't need a pass-
port," Pflaum said, "and I think it is
beautiful."
But neither of the programs sound
like the Hispanic-American stations
in Los Angeles, he said, because
they have more programming vari-
ety.
Listeners tuning in next week to
"Radio Caliente" - Sunday from 5-
6 p.m. - may be able to win free
Latin American records. "El Mundo
Latino" airs Thursday evenings from
6-6:30 p.m.
Both Vazquez and Pflaum are
seeking members of the Hispanic-
American community to join and
expand the programming.
