Anshelm, Jonas; Hansson, Anders (2015): Has the grand idea of geoengineering as Plan B run out of steam?

Anshelm, Jonas; Hansson, Anders (2015): Has the grand idea of geoengineering as Plan B run out of steam? In The Anthropocene Review. DOI: 10.1177/2053019615614592[nbsp]

„However, based on a reading of 700 articles published worldwide in 2014 and 2015, we demonstrate a gradual shift in the coverage, and the daily press now primarily reports critical views of geoengineering technologies. The patterns outlined here point in the same direction: It seems as though the grand idea of geoengineering as Plan B is fading.“

The Stanley Foundation; Perspectives (2015): Assessing Global Climte Engineering Governance. Policy dialogue brief

The Stanley Foundation; Perspectives (2015): Assessing Global Climte Engineering Governance. Policy dialogue brief. Zurich.

„This policy dialogue brief looks at five elements for enhancing global climate engineering governance: the development of knowledge, assessing technology options and deployment pathways, building institutional capacity, decisions and regulations on deployment, and a technology investment mechanism.“

Health Aim: Global Warming Solution – Hacking Nature

„Let’s take a closer look on how the concept of hacking nature will be done. Geoengineering was thought to give solution. An endangering 2-degree-celsius rise is said to possibly happen in the next decades to come. This will be devastating to nature and life. A rapid increase of carbon dioxide on air is making this happen little by little.“

Getty Science: Technological Fix Could We Stop Climate Change Using Science?

„One of the most interesting cases of a theoretical technological solution to a problem facing humanity is geoengineering. The idea behind it is that because we can’t stop the global warming using soft methods such as CO2 emission reduction, we should engineer the earth’s climate so that it cools down. Although most of the geoengineering ideas are at the outskirts of scientific research for now, there is a very interesting debate of whether they would be feasible or more importantly if their use would be ethical.“

Galarraga, Maialen (2015): The Making of a World. Climate Engineering as Creation

Galarraga, Maialen (2015): The Making of a World. Climate Engineering as Creation. In Charlotte Du Cann, Paul Kingsnorth, Tom Simth, Steve Wheeler (Eds.): Technê. Lancashire: Bracketpress (Dark Mountain, 8), pp.[nbsp]1–9.

„This creativity is always new and always unique, and there is no repetition to it:[nbsp]each society establishes a unique imaginary world and there is no articulation of a society that is given once and for all. However, modern societies have a tendency to think of technê as if it were nature – something that always occures in the same way. This misreading is what leaves modern societies unable to account for creative technê, and insensitive to different articulations of worlds.“

Kravitz, B.; et al. (2015): The Geoengineering Model Intercomparison Project Phase 6 (GeoMIP6). Simulation design and preliminary results

Kravitz, B.; Robock, A.; Tilmes, S.; Boucher, O.; English, J. M.; Irvine, P. J. et al. (2015): The Geoengineering Model Intercomparison Project Phase 6 (GeoMIP6). Simulation design and preliminary results. In Geosci. Model Dev. 8 (10), pp.[nbsp]3379–3392. DOI: 10.5194/gmd-8-3379-2015[nbsp]

We present a suite of new climate model experiment designs for the Geoengineering Model Intercomparison Project (GeoMIP). This set of experiments, named GeoMIP6 (to be consistent with the Coupled Model Intercomparison Project Phase 6), builds on the previous GeoMIP project simulations, and has been expanded to address several further important topics, including key uncertainties in extreme events, the use of geoengineering as part of a portfolio of responses to climate change, and the relatively new idea of cirrus cloud thinning to allow more longwave radiation to escape to space.

Gabriel, C. J.; Robock, Alan (2015): Stratospheric geoengineering impacts on El Niño/Southern Oscillation

Gabriel, C. J.; Robock, Alan (2015): Stratospheric geoengineering impacts on El Niño/Southern Oscillation. In Atmos. Chem. Phys. 15 (20), pp.[nbsp]11949–11966. DOI: 10.5194/acp-15-11949-2015[nbsp]

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 several scenarios: an instantaneous quadrupling of the atmosphere’s CO2 concentration, a 1 % annual increase in CO2 concentration, and the representative concentration pathway resulting in 4.5 W m−2 radiative forcing at the end of the 21st century, the Representative Concentration Pathway 4.5 scenario, with that under G1–G4 and under historical model simulations.
