Meadowcroft, James (2013): Exploring negative territory Carbon dioxide removal and climate policy initiatives

Meadowcroft, James (2013): Exploring negative territory Carbon dioxide removal and climate policy initiatives. In: Climatic Change 118 (1), pp. 137–149. DOI 10.1007/s10584-012-0684-1

"Over the last five years there has been increased scientific interest in the role carbon dioxide removal (CDR), or ‘negative carbon dioxide emissions’, might play in addressing anthropogenic climate change. [...] This article engages with these issues, considering the significance of CDR approaches for climate policy."

Martiny, Adam C.; et al. (2013): Strong latitudinal patterns in the elemental ratios of marine plankton and organic matter

Martiny, Adam C.; Pham, Chau T. A.; Primeau, Francois W.; Vrugt, Jasper A.; Moore, J. Keith; Levin, Simon A.; Lomas, Michael W. (2013): Strong latitudinal patterns in the elemental ratios of marine plankton and organic matter. In: Nature Geosci 6 (4), pp. 279–283. DOI 10.1038/ngeo1757

Study that is connected to ocean fertilization. "Here we assess global patterns in the elemental composition of phytoplankton and particulate organic matter in the upper ocean, using published and unpublished observations of particulate phosphorus, nitrogen and carbon from a broad latitudinal range, supplemented with elemental data for surface plankton populations."

SciDev: Concerns grow over effects of solar geoengineering

Media response to Bony; et al. (2013). "The latest studies on solar geoengineering to tackle climate change are reinforcing the case for a global governance system and further study before deployment, as they show that the approach may have little effect on preventing rainfall changes in the tropics — and may even lead to widespread drought in Africa."

Robock, Alan et al. (2013): Studying Geoengineering with Natural and Anthropogenic Analogs (accepted)

Robock, Alan; MacMartin, Douglas G.; Duren, Riley; Christensen, Matthew W. (2013): Studying geoengineering with natural and anthropogenic analogs. In: Climatic Change. DOI 10.1007/s10584-013-0777-5

"[T]here are also natural and anthropogenic analogs to SRM, such as volcanic eruptions in the case of stratospheric aerosol injection and ship tracks in the case of marine cloud albedo modification. It is essential to understand what we can learn from these analogs in order to validate models, particularly because of the problematic nature of outdoor experiments."
