Geoengineering – deliberate manipulation of the physical, chemical, or biological aspects of the Earth’s environment – is increasingly being discussed as a mechanism for combating climate change, especially in the world’s current political climate.
The Australian Academy of Science, together with the Academy of Technological Sciences and Engineering, has invited proponents and opponents of this controversial area of science to an Australian-first symposium at the Shine Dome in Canberra on 26 and 27 September, to explore the ideas and their potential effects and repercussions.
Geoengineering strategies propose either removing greenhouse gases from the atmosphere or decreasing the sun’s incoming radiation to reduce global warming. Various techniques include adding iron to the ocean to enhance carbon dioxide uptake or injecting small particles into the upper atmosphere to reflect the sun’s radiation.
Opponents argue that geoengineering could have unexpected consequences on a global scale and will work against efforts to to reduce emissions of greenhouse gases from human activities.
Proponents argue that the risks associated with geoengineering may be the lesser of two evils as climate change becomes ever more pronounced.
