2025-01-11 Paul Bierman – When the Ice is Gone

THE LECTURE Cold War Science and Engineering Today Reveals Greenland’s Fragility in an Overheating Climate     QGS hosted Paul at 4 PM on January 11, 2025 Paul’s lecture focused on how Greenland, a remote arctic island, holds in its ice enough water to raise sea level over six meters (20 feet). That is enough to flood every major coastal city and displace up to half a billion people. As he discussed, until recently we knew very little about the past comings and goings of this massive ice sheet. Through the lens of climate science, environmental history, and the stories… Read more2025-01-11 Paul Bierman – When the Ice is Gone

2025-02-15 Jeff Tepper – Diamond: A Multifaceted Gem

LECTURE – Diamond:  A Multifaceted Gem   QGS hosted former QGS advisor and emeritus professor, Jeff Tepper on February 15, 2025. Jeff’s lecture described that diamonds have been revered as precious stones for over 2000 years, yet they are composed simply of carbon, one of the most common elements on Earth. He explained their rarity arises from the fact that they form at extreme pressures deep in the Earth’s mantle and then are brought rapidly to the surface in CO2-rich explosive eruptions. No such eruptions have occurred in human history, but we know they occur only in the interiors of continents,… Read more2025-02-15 Jeff Tepper – Diamond: A Multifaceted Gem

2025-03-08 Dan Coe – Mapping Our Glacial Legacy

The Lecture: Mapping the Glacial Legacy of the Pacific Northwest Glaciers have shaped much of the Pacific Northwest’s landscape over the past 15,000 years. The Cordilleran ice sheet, repeated ice age floods, and expansive alpine glaciation have left their distinctive fingerprints on the topography of our region. Geologists and cartographers have been mapping and interpreting glacial landforms since the late 19th century. In the past decade, the Washington Geological Survey has created new maps that build upon this rich cartographic history by fusing older datasets and techniques with modern insights and technology, such as lidar. Using both historical and modern maps,… Read more2025-03-08 Dan Coe – Mapping Our Glacial Legacy
