About This Website

Peter Langdon Ward

This website was written by Dr. Peter Langdon Ward, a geophysicist, who retired from the United States Geological Survey in 1998 after 27 years studying volcanoes, earthquakes, plate tectonics, and regional geology and as a leader in developing the U.S. National Earthquake Hazards Reduction Program.

In 2006, he found well-documented evidence that there was major volcanism at the end of the last ice age, implying that volcanism may have caused the warming. This was an enigma because major explosive volcanoes are well observed to cause cooling. He realized that understanding this enigma might lead to important insights into climate change. So he gave up most other activities, devoting nearly full-time effort, working systematically across relevant aspects of the fields of volcanology, glaciology, climatology, atmospheric chemistry, atmospheric physics, basic physics, spectral physics, and quantum electrodynamics.
