We are living in a time of unprecedented and rapid technological, economic, social, and environmental change. I will argue that, in spite of what seems to be ever greater technological complexity, the largest scale natural “operations” of Earth are actually undergoing an unnoticed simplification, one that is already affecting geological landscapes, biodiversity, global economy, and human population. I will make predictions about specific “simplifications” that will accrue from sea-level rise, climate instability, diminishing petroleum output, increasing population, and dwindling global food supply. Whether these simplifications happen fast enough to allay an actual mass extinction (of our species) rather than “just” the current and expanding “mass depletion” over the next century, remains to be observed.
Dr. Peter Ward is a paleontologist and astrobiologist at the University of Washington and a world-renowned authority on mass extinctions, climate change, evolution, and astrobiology. His research examines the history of life on Earth over billions of years, focusing in particular on mass extinction events. That work gives him unique ‘deep time’ perspectives on the future of life on this planet, as well as the possibility of life elsewhere in the universe. Dr. Ward has appeared on NOVA and Ted Talks and written over a dozen popular science books including “Rivers in Time: the Search for Clues to Earth’s Mass Extinctions” and “The Flooded Earth: Our Future In a World Without Ice Caps”.
July 15th and July 31st
Geology group advisors Kitty Reed, Michael Machette, and Keith Norlin led two beach walks along the bluff on the north side of Fort Worden. These walks took 2-3 hours each and occurred during morning low tides: July 15, Mon., 9-12; July 31, Wed. 9:30-12:30. We looked at the sediments that record much of the late Pleistocene history of the area, as well as on-going bluff erosion. A fee of $10 per person (paid at time of field trip) was charged to cover our photocopy costs. Each trip was limited to 15 persons, and registration deadline is a week before each trip.
