„Over the past few weeks, the topic of geoengineering has popped up a lot in my newsfeeds. It’s not a new conversation, but seems to be making a revival post the UN Climate Summit last year[nbsp]where world leaders recognised the urgency of working together to find solutions.“
„Climate researchers are turning their minds to Plan B – manipulating the atmosphere to engineer a return to liveable conditions.“
Caseldine, Chris (2014): So what sort of climate do we want? Thoughts on how to decide what is ‘natural’ climate. In The Geographical Journal, pp. n/a. DOI 10.1111/geoj.12131.
„Any decisions on forms of geoengineering, enhanced or reduced GHG use will lead to a climate response and a global climate that is inevitably to some extent anthropogenically determined. It is therefore of value to pose the question: So what sort of climate do we want?“
Jackson, L. S.; Crook, J. A.; Jarvis, A.; Leedal, D.; Ridgwell, A.; Vaughan, N.; Forster, P. M. (2015): Assessing the controllability of Arctic sea ice extent by sulfate aerosol geoengineering. In Geophys. Res. Lett., pp. n/a. DOI 10.1002/2014GL062240.
„n an assessment of how Arctic sea ice cover could be remediated in a warming world, we simulated the injection of SO2 into the Arctic stratosphere making annual adjustments to injection rates. We treated one climate model realisation as a surrogate ‘real world’ with imperfect ‘observations’ and no re-running or reference to control simulations.“
Newspaper article citing Cairns, Rose (2014). „As farfetched (and baseless) as these claims may be, a recent scholarly analysis of the chemtrails movement suggests we can’t write off its relevance entirely — not because its proponents are right, but because of the insights they may offer about a future debate over geoengineering.“
„However, two recent publications are breaking the ice and bringing the discussion of field experiments into the limelight of the scientific community.“
Kiel Earth Institut (2014): Modelling in Climate Engineering Research. Significance and Uncertainties. Priority Programme 1689 of the German Research Foundation DFG.
„In the priority programme “Climate Engineering: Risks, Challenges, Opportunities?” (SPP 1689), we want to provide a comprehensive evaluation of the ideas that have emerged on Climate Engineering (CE) in science and climate politics in recent years. […] With the resulting brochure, we hope to inform both scientists and interested members of the public about the basic aspects of our research, thereby making it easier to join the discourse on CE.“
Linnér, Björn-Ola; Wibeck, Victoria (2015): Dual high-stake emerging technologies: a review of the climate engineering research literature. In WIREs Clim Change, pp. n/a. DOI 10.1002/wcc.333.
„This paper presents a comprehensive review of social and natural science papers on this topic since 2006 and listed in SCOPUS and Web of Science. It adds to previous literature reviews by combining analyses of bibliometric patterns and of trends in how the technologies are framed in terms of content, motivations, stakes, and recommendations.“
Including CE. „We’ve built canals between oceans and tunnels under the sea. But some engineers are thinking bigger“
Anand, S.; Mayya, Y. S. (2015): Comment on „Reduced efficacy of marine cloud brightening geoengineering due to in-plume aerosol coagulation: parameterization and global implications“ by Stuart et al. (2013). In Atmos. Chem. Phys. 15 (2), pp. 753–756. DOI 10.5194/acp-15-753-2015.
Response to Stuart et al. (2013). „We examine the parameterized model of Stuart et al. (2013) vis-à-vis a diffusion-based model proposed by us earlier (Anand and Mayya, 2011) to estimate the fraction of aerosol particles surviving coagulation in a dispersing plume. While the Stuart et al. approach is based on the solutions to the coagulation problem in an expanding plume model, the diffusion-based approach solves the diffusion–coagulation equation for a steady-state standing plume to arrive at the survival fraction correlations.„
