Branch Members Attend Crutzen Seminar at UMD
December 7, 2005
Dr. Paul Crutzen who received the 1995 Nobel Prize in Chemistry presented a seminar on "Atmospheric Chemistry and Climate in the 'Anthropocene'", Thursday night December 1 at the University of Maryland. Dr. Crutzen's main message was that we have entered a new geologic era beginning roughly two hundred years ago, the Anthropocene, the era in which human activity dominates the Earth System. He provided several detailed examples of climate scale anthropogenic effects including the atmospheric chemistry that produced the ozone hole, and the role of aerosols and greenhouse gases in the climate system.
