NORMAN, Okla. (AP) -- Former Vice President Al Gore says dire environmental consequences will result if changes aren't made to reduce the greenhouse gases that humans put into the air and sea.
Gore spoke before an estimated crowd of about 7,000 people at the University of Oklahoma's Lloyd Noble Center. His appearance capped a day-long focus at OU on the global warming debate.
Earlier Thursday, two university professors held a forum on the issue in the campus' student union, and more than 500 people filled an auditorium and part of another room to hear the professors' arguments.
Governor Brad Henry, his wife, Kim, and one of their daughters attended the event, as did State Treasurer Scott Meachem and State Attorney General Drew Edmondson.
OU President David Boren, who served for eight years with Gore in the US Senate, says global warming isn't a subject to discuss but one to live out.
