“Ice Ages: Past, Present, and Future”

Journey Back to the Time When Ice Ruled.

Over the past 700 million years, our earth has rarely displayed permanent ice caps like we see now. When you take this long-term perspective, we’re in an ice age—a time of widespread glaciation—right now. And since glaciers are in retreat and ice is mainly found in polar regions, geologists consider our earth to be in an “interglacial period,” a time of warmer temperatures that separates colder periods within an ice age. What actually caused glaciers to expand and cover all of Canada and the northern USA? The answer appears to be our changing relationship with the sun. Long-term cycles alter the shape of our orbit and the tilt of our planet’s rotational axis. These changes have a profound impact on earth’s climate.

Now, human activity may overwhelm these natural cycles. Does that mean our interglacial period will come to an end? The answer to this question is surprisingly complex. While we cannot ignore the effects of greenhouse gases, our sun may have a surprise in store. Even with increasing greenhouse gas emissions, we might experience a mini ice age in the near future.

About Ron Smith
Ron Smith’s teaching and lecturing career began at age 9 when his farther took him to see a planetarium show at the Griffith Observatory. Ten year’s later Ron’s dream came true when he began giving planetarium shows at Griffith while pursing an astronomy degree at the University of Southern California. After graduating from USC, Ron began his 34 year teaching career in the California Community College system. He first directed the Tessmann Planetarium at Santa Ana College, then two years later, became a professor of astronomy at Santa Monica College. In 1984 he left Southern California and taught for 18 years at Santa Rosa Junior College. There he produced planetarium programs for the college star theater, and taught astronomy, meteorology, and earth science.

Ron Smith considers himself to be a planetarium educator. His experience in junior college teaching, public lecturing at the Page Museum of Natural history, and planetarium show production gives him a broad based science background. In retirement, Ron continues to enjoy sharing his love of science with audiences at Sunriver, Dixie State University, and the Kayenta Center for the Performing Arts.

The Voyager Lecture Series is sponsored by Voyager Wealth Advisors, Inc., Cache Valley Bank, and State Farm Insurance Agent Sherry McGhee.

This lecture will begin at 7:30pm on September 24th. An informal gathering beings at 6:30pm. Tickets are $15 including refreshments.

Voyager Lecture Series Featuring Ron Smith Tickets are $15 (Sept 24, 7:30pm, gathering at 6:30pm)
