Salby, M. 2011 Presentation: Global Emission of Carbon Dioxide: The Contribution from Natural Sources

Prof. Salby presents scientific evidence that man-made emissions do not control global CO2 levels, do not control the climate, and that temperature controls CO2 levels (rather than CO2 controlling temperature) on a yearly time scale…….hmmm.  Click here for a podcast presented at The Sydney Institute on August 2, 2011.

Atmospheric Science, Climate Change and Carbon – Some Facts

 Carbon dioxide is emitted by human activities as well as a host of natural processes. The satellite record, in concert with instrumental observations, is now long enough to have collected a population of climate perturbations, wherein the Earth-atmosphere system was disturbed from equilibrium. Introduced naturally, those perturbations reveal that net global emission of CO2 (combined from all sources, human and natural) is controlled by properties of the general circulation – properties internal to the climate system that regulate emission from natural sources. The strong dependence on internal properties indicates that emission of CO2 from natural sources, which accounts for 96 per cent of its overall emission, plays a major role in observed changes of CO2. Independent of human emission, this contribution to atmospheric carbon dioxide is only marginally predictable and not controllable.

Professor Murry Salby holds the Climate Chair at Macquarie University and has had a  lengthy career as a world-recognised researcher and academic in the field of Atmospheric Physics. He has held positions at leading research institutions, including the US National Center for Atmospheric Research, Princeton University, and the University of Colorado, with invited professorships at universities in Europe and Asia. At Macquarie University, Professor Salby uses satellite data and supercomputing to explore issues surrounding changes of global climate and climate variability over Australia. Professor Salby is the author of Fundamentals of Atmospheric Physics, and Physics of the Atmosphere and Climate due out in 2011. Professor Salby’s latest research makes a timely and highly-relevant contribution to the current discourse on climate.
