2016, January 11, 11:30 am, the American Meteorological Society Annual Meeting, Talk entitled Mario Molina’s research not only led to the solution for the Antarctic ozone hole, but it led to the solution for global warming caused by humans since 1960. This talk is part of the Mario J. Molina Symposium. Mario J. Molina received the Nobel Prize in Chemistry in 1995, together with Paul Crutzen and F. Sherwood Rowland, “for their work in atmospheric chemistry, particularly concerning the formation and decomposition of ozone.” [Abstract]

2015, December 18, The American Geophysical Union Fall Meeting, poster presentation entitled Climate throughout geologic time was cooled by sequences of explosive volcanic eruptions forming aerosols that reflect and scatter ultraviolet solar radiation and warmed by relatively continuous extrusion of basaltic lava that depletes ozone, allowing more solar ultraviolet radiation to reach earth. [Abstract]

2015, November 1, 8:15 am, Geological Society of America Annual Meeting, talk entitled Climate throughout geologic time has been controlled primarily by the balance between abrupt warming caused by voluminous effusive eruptions of basaltic magma over months to hundreds of thousands of years and abrupt cooling caused by major explosive eruptions of evolved magmas over hours to days. [Abstract] [Talk]

2015, October 28, TEDx Wilmington, Volcanoes: A Forge for Climate Change. Dr. Peter Langdon Ward worked 27 years as a geophysicist with the United States Geological Survey, being featured on Good Morning America and winning two national awards for explaining science to non-scientists. Nine years ago, while in retirement, he found reliable data suggesting that volcanic eruptions not only cool the earth for a few years, something that is well known, but also can warm the earth substantially. How could this be? Realizing the importance of figuring this out, he set off on a full-time quest trying to understand in detail how volcanism has controlled climate throughout Earth history, throughout the evolution of our species, throughout written history, and why 2015 is the hottest year on record. [Talk] (Video available by December.)

2015, May 21-23, Geological Society of America Rocky Mountain Section, Climate throughout geologic time has been controlled primarily by the balance between cooling caused by major explosive eruptions of evolved magmas typical of island arcs and warming caused by voluminous effusive eruptions of basaltic magma typical of subaerial ocean ridges, island chains, and continental flood basalts [Abstract] [Talk]
