The most comprehensive review of the impact of aviation on climate this century has been presented by a collaborated effort of two schools.
A unique collaboration between the University of Southampton's Schools of Engineering Sciences and Medicine, has presented the review and has been awarded the Royal Aeronautical Society Silver Medal in London.
AdvertisementThe paper entitled 'Systematic review of the impact of emissions from aviation on current and future climate' is the first major study of its kind in the last decade, since the Intergovernmental Panel on Climate Change published its findings on this subject in 1999.
Dr. Kenji Takeda, Senior Lecturer in the School of Engineering Sciences and lead author of the paper explains: "By using an objective approach to reviewing the effect of aircraft on climate, we hope to provide a good baseline for this active debate. There is a clear need for improving scientific understanding, and it is vital for the aircraft industry to continue to support climate scientists and work towards future solutions for sustainable aviation."
The Southampton collaboration is unique in the sense that the application of the systematic review methodology for drug appraisals is subject to climate change. The results of the paper show that there is a wide range of predictions for the impact of aviation on climate. These are most dependent on assumptions made about future economic growth. The paper also highlights how dependent we are on the level of scientific understanding and modeling capability, particularly around the non-CO2 effects of aircraft.
Systematic reviews are carried out to identify and synthesize evidence using a transparent and objective approach. They are used extensively by medical researchers for assessing the effectiveness of methods for preventing, treating and managing different diseases, to inform national policy in the UK on their availability across the National Health Service. This is one of the first times this rigorous approach has been applied to the complex issues around climate change. It is hoped that such objective methodology can be more widely applied in this area to help inform and guide the decision-making process that will determine the future of the planet.
