Professor Darin Toohey lectures on "Saving the World's Ozone Layer ", an overview of two decades of research into the impacts of mankind's activities on the fragile ozone layer upon which the World depends. During his fascinating career, Prof. Toohey has conducted numerous stratospheric research projects with NASA and is presently a Science Fellow at the U.S. Department of State.

Prof. Toohey describes his field work principally involving high altitude aircraft and balloons. He examines the role of field observations of trace gases and aerosols in defining the impact of human activities on the atmospheric environment. He also describes his work that for the first time defined the role of chlorofluorocarbons and brominecontaining species on ozone destruction over the Arctic and Antarctic, solidifying the case for the international agreements which followed to protect the ozone layer.

Prof. Toohey also presents his most recent work that explores the enhanced impact of emissions from space rockets going directly into the stratosphere on ozone and climate change, even though they represent only a small fraction of the total exhaust from rockets.

Prof. Toohey concludes that mankind has the ability to alter the Earth's climate through the injection of particles into the stratosphere or "solar radiation management " and, consequently, that mankind has the responsibility to study and regulate activities that inadvertently influence the Earth's climate, in addition to those designed to intentionally alter it by "geoengineering ".

Darin Toohey is Professor of Atmospheric Sciences at the University of Colorado Boulder. He has been at the forefront of research on stratospheric ozone since the early 1980s. His work addresses the chemistry and dynamics of the Earth's atmosphere, with particular emphasis on observations of trace gases and aerosols and their impact on chemistry and climate. He has participated in over 40 field campaigns from around the globe, including in remote locations such as Antarctica and Spitsbergen.

He has authored over 100 publications and he has served with numerous scientific organisations. Amongst a number of awards he received a National Science Foundation Award, the award for an outstanding publication of the American Chemical Society and multiple NASA group achievement awards. He has served as Editor of the Journal of Geophysical Research Atmospheres and Atmospheric Measurement Techniques. He is currently serving as a Jefferson Science Fellow at the U.S. Department of State where he works on green growth and energyrelated issues.
