Friday 13 March: 7:30pm - 9:30pm Lady Mitchell Hall, Sidgwick Site Sidgwick Avenue, CB3 9DA Climate engineering is a contentious issue in part due to a perceived lack of progress on crucial emission reductions. Is it a dangerous distraction from the work needed to reduce emissions or could solar radiation management be a straightforward way of mediating climate change? Join Oliver Morton and Professors Martin Rees, Amartya Sen, Onora O’Neill and David Keith to find out more. This event forms part of the International Solar Radiation Management Science 2015 Conference organised by the Department of Engineering, University of Cambridge.

This is a question that perhaps we shouldn't even ask because it will distract us from our primary goal of reducing CO2 emissions. But seriously, what if our CO2 reduction efforts don't work? Do we just accept the climate consequences of the CO2 we generate (35 billion tonnes we emit annually) - sea level rise, desertification, ocean acidification, loss of habitat - or do we try to fix the damage that we are causing? There are several viable technologies for controlling the climate - known as "geoengineering". Carbon Dioxide Removal (CDR) by sequestering CO2 is one, or Solar Radiation Management (SRM) using space reflectors is another. The SPICE project (Stratospheric Particle Injection for Climate Engineering) investigates the benefits, risks, costs and feasibility of SRM by injecting reflective aerosols in the atmosphere. If particles can be pumped into the stratosphere at an altitude of 20km, emulating the effects of a large volcanic eruption, then global cooling of about 2 degC can be achieved. The particles would be pumped through a number of high-pressure pipes suspended by balloons. SPICE presents many novel engineering challenges, especially the design of the pipe and pumping systems to withstand pressures up to 4000 bar and tensions up to 500 tonnes. In this non-technical introductory presentation a number of these challenges will be discussed. Dr. Hugh Hunt is a Senior Lecturer in the Department of Engineering at Cambridge University, and a Fellow of Trinity College. His principal interests are in dynamics and vibration, gyroscopes and boomerangs. His most recent research is in the fields of renewable energy and geoengineering, including the SPICE project - technology for cooling the Earth by 2 degrees C if CO2 emissions targets are not met. Other research includes the control of vibration from underground railways, bells and clocks and wind turbines. He does television work and was Lead Engineer in award-winning documentaries ("Dambusters: building the bouncing bomb", "Digging the Great Escape", "Escape from Colditz" and "Attack of the Zeppelins") which have been broadcast around the world. He took his first degree in Engineering from Melbourne University, Australia and has a PhD from Cambridge. He has accumulated an impressive collection of boomerangs, many of them home made. He uses these to inspire students in the study of Dynamics and Mechanics. - See more at: http://www.sciencefestival.cam.ac.uk/events/engineering-our-climate#sthash.iSqu4z8v.dpuf -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
