KIB: Climate Engineering – A Technofix to Solve the Problem of Climate Change?

„In this article, we take up these questions, arguing that talking about climate engineering as a technological solution to a social problem – i.e., climate change – can discursively lead to the side-lining of these repercussions and of alternative solutions to climate change. To do so, we will first lay out the rationale of climate engineering and explain what it is. In a second step, we identify potential technical and political side-effects before we critically discuss whether in the current debate climate engineering being framed as a ‘technological fix’. In the conclusion, we summarize our argumentation and provide an outlook on the politics of climate engineering.“

„Using a global climate model, we investigate the hydrological cycle response to ‘cirrus cloud thinning (CCT)’, which is a proposed climate engineering technique that seeks to enhance outgoing longwave radiation. Investigations of the ‘fast response’ in experiments with fixed sea surface temperatures reveal that CCT causes a significant enhancement of the latent heat flux and precipitation. This is due to enhanced radiative cooling of the troposphere, which is opposite to the effect of increased CO2 concentrations.“

„The Forum for Climate Engineering Assessment asked one of its researchers to answer the question: “Who is saying what about the likelihood of staying below a 2 degrees Celsius rise above pre-industrial atmospheric temperatures?” The results beg the question, should researchers and policy-makers be thinking more seriously and openly about climate engineering research?“

„Geoengineering is moving from modelling to field experiments, with potentially significant environmental, social and ethical impacts. Impact assessments are normally undertaken to determine the risks of such activities. But new research suggests international law is currently insufficiently tailored to the particular assessment challenges posed by geoengineering“
