Speaker discusses weather climate change

Internationally acclaimed scientist and activist Timothy Flannery visited Susquehanna Thursday evening to present a global warming lecture as part of the Claritas Distinguished Speaker in the Sciences Series.

The speech, presented in the Degenstein Theater, featured Flannery, a professor of division of environmental and life sciences at Macquarie University in Sydney, Australia.
He spoke about global warming and its threats and said that it is an imminent threat that can only be solved with teamwork.

"We must all work in harmony and with coordinated efforts to save this indivisible planet of ours," Flannery said.

The lecture began with information about the earth's atmosphere, or as Flannery called it, "the great aerial ocean." The atmosphere is so intimately connected with life that it is actually a manifestation of life that must be taken care of, he said.

The gases in our atmosphere -- specifically the ozone layer -- are what protect us from harmful UV?rays and keep the world inhabitable for human life and should be looked at as something to conserve and treasure, he said.

Flannery then turned his attention to acid rain and greenhouse gases: two topics that may sound like old news, but are still considered by scientists today to be the most destructive elements depleting the ozone layer.

Scientists first became aware of holes in the ozone layer in the 1970s, but the holes have since become a more serious issue. Katherine Straub, assistant professor of earth and environmental science at Susquehanna, said in her introduction that "once upon a time, global warming was thought to be our grandchildren's problem." She said it has become everyone's problem, so everyone must cooperate to help fix it.

Flannery said that large-scale climate changes can happen very rapidly and that people must pay more attention to their day-to-day activities in order to bring about ozone-layer repairs. He said that Americans should reduce gas emissions on a large scale --by as much as 80 percent by the year 2050.

Flannery's book, "The Weather Makers: How Man is Changing the Climate and What It Means for Life on Earth," is a New York Times best-seller that relates his global warming points to readers in a scientifically viable, yet understandable, way.
