the guardian: Could artificial trees be part of the climate change solution?

"Real trees are forced to work harder as more carbon is released into the atmosphere. Technology could share the load"

Baatz, Christian (2016): Can We Have It Both Ways? On Potential Trade-Offs Between Mitigation and Solar Radiation Management

Baatz, Christian (2016): Can We Have It Both Ways? On Potential Trade-Offs Between Mitigation and Solar Radiation Management. In environ values 25 (1), pp. 29–49. DOI 10.3197/096327115X14497392134847. (final paper)

"Many in the discourse on climate engineering agree that if deployment of solar radiation management (SRM) technologies is ever permissible, then it must be accompanied by far-reaching mitigation of greenhouse gas (GHG) emissions. This raises the question of if and how both strategies interact. Although raised in many publications, there are surprisingly few detailed investigations of this important issue. The paper aims at contributing to closing this research gap by (i) reconstructing moral hazard claims to clarify their aim, (ii) offering one specific normative justification for far-reaching mitigation and (iii) investigating in greater detail different mechanisms that could potentially cause a trade-off between mitigation and SRM."

Tjiputra, J. F.; et al. (2016): Impact of idealized future stratospheric aerosol injection on the large scale ocean and land carbon cycles

Tjiputra, J. F.; Grini, A.; Lee, H. (2016): Impact of idealized future stratospheric aerosol injection on the large scale ocean and land carbon cycles. In J. Geophys. Res. Biogeosci., pp. n/a-n/a. DOI 10.1002/2015JG003045.

"Using an Earth system model, we simulate stratospheric aerosol injection (SAI) on top of the Representative Concentration Pathways 8.5 future scenario. Our idealized method prescribes aerosol concentration, linearly increasing from 2020 to 2100, and thereafter remaining constant until 2200. In the aggressive scenario, the model projects a cooling trend toward 2100 despite warming that persists in the high latitudes."

Smith, Pete (2016): Soil carbon sequestration and biochar as negative emission technologies

Smith, Pete (2016): Soil carbon sequestration and biochar as negative emission technologies. In Global Change Biology. DOI 10.1111/gcb.13178.

"In this paper, I assess the potential for negative emissions from soil carbon sequestration and biochar addition to land, and also the potential global impacts on land use, water, nutrients, albedo, energy and cost. Results indicate that soil carbon sequestration and biochar have useful negative emission potential (each 0.7 GtCeq. yr−1) and that they potentially have lower impact on land, water use, nutrients, albedo, energy requirement and cost, so have fewer disadvantages than many NETs."

Envirotidings: Geo-engineering the climate: Possible remedy or colossal catastrophe?

"The application of geo-engineering as a proposed solution to climate change must be exercised with caution, as it can have numerous damaging and unknown consequences. In a desperate effort to produce innovative ideas to combat climate change, scientists are proposing solutions that range from practical to colossally extreme in their impacts. [...] It appears that rather than promoting solutions on smaller scales, such as at the individual and community levels, a number of scientists are looking to engage in grand solutions that appear promising, but can in fact be disastrous. Doug Parr, chief scientist for Greenpeace UK, strengthens this argument by saying that: “the scientific community is becoming so scared of our collective inability to tackle climate emissions that such outlandish schemes are being considered for serious study.”"
