Wibeck, Victoria; Hansson, Anders; Anshelm, Jonas (2015): Questioning the technological fix to climate change – Lay sense-making of geoengineering in Sweden. In: Energy Research [&] Social Science 7 (0), S. 23–30. DOI: 10.1016/j.erss.2015.03.001.
„This paper explores how Swedish laypeople make sense of emerging ideas of the large-scale deliberate technical manipulation of the global climate, known as geoengineering (GE). The paper is based on semi-structured focus group interviews with open-ended questions, allowing participants to express their spontaneous thoughts about GE.“
Cunha, Daniel (2015): The Anthropocene as Fetishism. In: Mediations 28 (2), S. 65–77.
„In fact, this means taking the promise of the Anthropocene very seriously, that is, Man should take conscious control of planetary material cycles, extend the terrain of the political hitherto left to the blind mechanics of nature and, in capitalism, to commodity fetishism.64 And this not only because the productive forces developed by capitalism allow it — although up to now we do it without conscious social control — but also because it might be necessary.“
„You might think that the volume of aerosols needed to increase the Earth’s reflectivity (known as albedo) enough to halt global climate change would be enormous. But speaking to Kishore Hari on this week’s Inquiring Minds podcast, Caldeira explains that „if you had just one firehose-worth of material constantly spraying into the stratosphere, that would be enough to offset all of the global warming anticipated for the rest of this century.“
Horton, J. B. (2015): The emergency framing of solar geoengineering: Time for a different approach. In: The Anthropocene Review. DOI: 10.1177/2053019615579922.
„Solar geoengineering has been proposed as a possible response measure in the event of a ‘climate emergency’. Scientific evidence for climate emergencies in the form of tipping points, however, is contested and unsettled.“
Non-professional dictonary definition. „Loosely defined as the intentional large-scale manipulation of the global environment; planetary tinkering; a subset of terraforming or planetary engineering.“
Gabriel, C. J.; Robock, A. (2015): Stratospheric geoengineering impacts on El Niño/Southern Oscillation. In: Atmos. Chem. Phys. Discuss. 15 (6), S. 9173–9202. DOI: 10.5194/acpd-15-9173-2015.
„To examine the impact of proposed stratospheric geoengineering schemes on the amplitude and frequency of El Niño/Southern Oscillation (ENSO) variations we examine climate model simulations from the Geoengineering Model Intercomparison Project (GeoMIP) G1–G4 experiments. Here we compare tropical Pacific behavior under anthropogenic global warming (AGW) using the representative concentration pathway resulting in 4.5 W m−2 radiative forcing at the end of the 21st Century, the RCP4.5 scenario, with that under G1–G4 and under historical model simulations.„
Radio broadcast. „On the show this week we talk to Ken Caldeira, a climate scientist working for the Carnegie Institution for Science, Department of Global Ecology at Stanford University. He investigates issues related to climate, carbon, and energy systems.“
Di Paola, Marcello (2015): Virtues for the Anthropocene. In: environ values 24 (2), S. 183–207.
„The paper discusses some difficulties that life in Anthropocene poses to our ethical thinking. It describes the sort of ethical task that individuals find themselves confronting when dealing with the planetary environmental quandaries that characterise the new epoch.“
„Let’s hope by the time they get to the field-testing, geoengineering proponents have a better handle on the actual planetary response to manipulation. Otherwise, geoengineering will have a short and disastrous run.“
