Spears, Bryan M.; et al. (2013): Geo-Engineering in Lakes—A Call for Consensus

Spears, Bryan M.; Dudley, Bernard; Reitzel, Kasper; Rydin, Emil (2013): Geo-Engineering in Lakes—A Call for Consensus. In: Environ. Sci. Technol., DOI 10.1021/es401363w

"Unlike proposals for atmospheric manipulations, geo-engineering in lakes and reservoirs using phosphorus(P)-removing materials has been implemented at a global scale as a eutrophication management tool for decades, in the absence of scientific consensus on its use."

Morgan, M. Granger; et al. (2013): Needed: Research Guidelines for Solar Radiation Management

Morgan, M. Granger; Nordhaus, Robert R.; Gottlieb, Paul (2013): Needed: Research Guidelines for Solar Radiation Management. In: Issues in Science & Technology (Spring).

"As this approach to geoengineering gains attention, a coordinated plan for research will make it possible to understand how it might work and what dangers it could present."

Hanafi, Alex; Hamburg, Steven P. (2013): The Solar Radiation Management Governance Initiative: Advancing the International Governance of Geoengineering Research

Hanafi, Alex; Hamburg, Steven P. (2013): The Solar Radiation Management Governance Initiative: Advancing the International Governance of Geoengineering Research. Opinion Article (‘Geoengineering Our Climate?’ Working Paper and Opinion Article Series, 1).

"The most difficult issues lie in the areas of ethics, politics, and governance.  As communities and policymakers around the world face the risks presented by a rapidly changing climate, understanding the scientific, ethical, and governance issues at the core of geoengineering research will be critical to making informed decisions about response options."

Canty, T.; et al. (2013): An empirical model of global climate – Part 1: A critical evaluation of volcanic cooling

Canty, T.; Mascioli, N. R.; Smarte, M. D.; Salawitch, R. J. (2013): An empirical model of global climate – Part 1: A critical evaluation of volcanic cooling. In: Atmos. Chem. Phys. 13 (8), pp. 3997–4031. DOI 10.5194/acp-13-3997-2013

Paper on vulcanic cooling via aerosols with a link to SRM. "Finally, we highlight possible shortcomings in simulations of volcanic cooling by general circulation models, which are also being used to assess the impact of geoengineering of climate via stratospheric sulfate injection."

Jaffe, R.; et al. (2013): Global Charcoal Mobilization from Soils via Dissolution and Riverine Transport to the Oceans

Jaffe, R.; Ding, Y.; Niggemann, J.; Vahatalo, A. V.; Stubbins, A.; Spencer, R. G. M. et al. (2013): Global Charcoal Mobilization from Soils via Dissolution and Riverine Transport to the Oceans. In: Science 340 (6130), pp. 345–347.

Related to biochar. "We have quantified dissolution products of charcoal in a wide range of rivers worldwide and show that globally, a major portion of the annual charcoal production is lost from soils via dissolution and subsequent transport to the ocean."
