THINK Debate: Climate Emergency: Should we Consider Geoengineering?

We find ourselves in a climate emergency. In the words of UN Secretary-General António Guterres, this is ‘code red for humanity’. Many worry that transitioning to renewable energy, decreased consumption and more sustainable living will not happen fast enough or be sufficient to stop the worst effects of climate change. With little time to act, some ask that geoengineering schemes be considered. As the ETC groups writes, “geoengineering can refer to a wide range of techniques, including: blasting sulphate particles into the stratosphere or 'whitening' clouds to reflect the sun’s rays; dumping iron particles in the oceans to nurture CO2 -absorbing plankton; firing silver iodide into clouds to produce rain or genetically engineering crops so their foliage can better reflect sunlight.” While advocates argue that such drastic actions are necessary, critics point not only to the risks of trying to manipulate complex systems that we do not fully comprehend, but also to the human rights implications and democratic challenges of allowing some countries to make choices that impacts on the whole Earth.
