Reason: We Broke the Climate and We Can Fix It

"It's way past time for humans to start devising an emergency back-up planetary cooling system. Should man-made global warming turn out to be faster and more intense than currently projected, we need a plan for how to respond. Geoengineering offers one possible answer."

Aljazeera: The Paris Agreement is deeply flawed - it's time for a new deal

"The Paris accord is built on speculative 'tech fantasies'. It can not save us from climate catastrophe."

earth.com: Climate geoengineering: Is cooling the planet worth the risk?

"New research is underway examining the potential costs and benefits of climate geoengineering to combat global warming. Geoengineering is certainly a controversial issue, as it requires the purposeful manipulation of climate to mitigate the effects of climate change, which some argue could have devastating side effects. But according to one Popular Science piece, it’s a way to “press pause” on the worsening impacts of global warming."

Moore, John C.; et al. (2018): Geoengineer polar glaciers to slow sea-level rise

Moore, John C.; Gladstone, Rupert; Zwinger, Thomas; Wolovick, Michael (2018): Geoengineer polar glaciers to slow sea-level rise. In Nature 555 (7696), pp. 303–305. DOI: 10.1038/d41586-018-03036-4.

"Stalling the fastest flows of ice into the oceans would buy us a few centuries to deal with climate change and protect coasts, argue John C. Moore and colleagues."

Ji, Duoying; et al. (2018): Extreme temperature and precipitation response to solar dimming and stratospheric aerosol geoengineering

Ji, Duoying; Fang, Songsong; Curry, Charles L.; Kashimura, Hiroki; Watanabe, Shingo; Cole, Jason N. S. et al. (2018): Extreme temperature and precipitation response to solar dimming and stratospheric aerosol geoengineering. In Atmos. Chem. Phys. Discuss., pp. 1–36. DOI: 10.5194/acp-2018-131.

"We examine extreme temperature and precipitation under two potential geoengineering methods forming part of the Geoengineering Model Intercomparison Project (GeoMIP). The solar dimming experiment G1 is designed to completely offset the global mean radiative forcing due to a CO2-quadrupling experiment (abrupt 4 × CO2), while in GeoMIP experiment G4, the radiative forcing due to the representative concentration pathway 4.5 (RCP4.5) scenario is partly offset by a simulated layer of aerosols in the stratosphere. Both G1 and G4 geoengineering simulations lead to lower maximum temperatures at higher latitudes, and on land primarily through feedback effects involving high latitude processes such as snow cover, sea ice and soil moisture."

Thiele, Leslie Paul (2018): Geoengineering and sustainability

Thiele, Leslie Paul (2018): Geoengineering and sustainability. In Environmental Politics 2 (1), pp. 1–20. DOI: 10.1080/09644016.2018.1449602.

"Geoengineering is regarded by advocates as a creative and responsible technological option in the face of a climate emergency. Critics often see it as a hubristic attempt to play God, with disastrous consequences for the planet and humanity. These antipodal perspectives are represented by the ideal types of Prometheans and Gaians. Prometheans and Gaians typically talk past each other. The geoengineering debate can be made more fruitful by well articulating their respective positions and subsequently situating them in the discourse of sustainability."

Buck, Holly Jean (2018): Perspectives on solar geoengineering from Finnish Lapland. Local insights on the global imaginary of Arctic geoengineering

Buck, Holly Jean (2018): Perspectives on solar geoengineering from Finnish Lapland. Local insights on the global imaginary of Arctic geoengineering. In Geoforum 91, pp. 78–86. DOI: 10.1016/j.geoforum.2018.02.020.

"However, this concept has remained a global imaginary, grounded in coarse-resolution climate modeling. How do people actually living in the Arctic imagine themselves experiencing or shaping solar geoengineering? How can the experience of people in particular places inform discussions of solar geoengineering governance? This paper synthesizes perspectives from extended interviews with citizen stakeholders in Finnish Lapland. Rather than approaching solar geoengineering from the perspective of Arctic or local interests, respondents took a global view of its prospects and governance."
