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. The Michigan Daily - Monday, October 17, 1988 - Page 3 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.

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.
