Prof. Douw Steyn, PhD, ACM, FCMOS, is Professor Emeritus of Atmospheric Science at The University of British Columbia, in the Department of Earth Ocean and Atmospheric Sciences. He is a member of the Institute for Applied Mathematics, the Institute for Resources, Environment and Sustainability, and the Liu Institute for Global Issues. He has served as Associate Dean (Research and Faculty Development) in the Faculty of Graduate Studies and Principal of the College for Interdisciplinary Studies. Prof. Steyn's professional, teaching and research activities are in the field of air pollution meteorology, boundary layer meteorology, mesoscale meteorology, environmental science and interdisciplinary science. His research involves measurement and modelling studies of regional air pollution, especially in regions with complex terrain. This work involves modelling of near-surface emissions of pollutants and their precursors, atmospheric flow and turbulence modelling, and modelling of chemical transformation of air pollutants. He has worked extensively on the statistics of air pollution, air pollution monitoring and monitoring network design Prof. Steyn is winner of a UBC Killam Teaching Prize, the Canadian Meteorological and Oceanographic Society Andrew Thompson Prize in Applied Meteorology, and the Canadian Federation for Earth Sciences Mentorship Medal. He is Chair of the scientific committee that leads the International Technical Meeting series on Air Pollution Modelling and its Application. He publishes regularly in the international peer reviewed literature, he is editor of the journal Atmosphere-Ocean, and serves on the editorial board of Boundary Layer Meteorology. He is an Accredited Consulting Meteorologist, and has international consultancy experience in his areas of expertise, and has provided expert testimony in numerous court cases and appeal board hearings in British Columbia. Prof. Douw Steyn will summarize various studies and observations that point towards global atmospheric warming and the associated changes in Earth climates. These will include instrumental and proxy near-surface temperature records, satellite derived atmospheric temperature profiles and global atmospheric CO2 measurements. He will examine the history of climate science, and will explain the nature and use of atmospheric numerical models, and how they are used to understand the causes of global warming. He will argue that on the balance of probabilities, the observed global warming, and associated climate changes are due to anthropogenic emission of CO2 and other greenhouse gases.
