Science Daily: Geoengineering the Climate Could Reduce Vital Rains

Response to Tilmes, Simone; et al. (2013). "Although a significant build-up in greenhouse gases in the atmosphere would alter worldwide precipitation patterns, a widely discussed technological approach to reduce future global warming would also interfere with rainfall and snowfall, new research shows."

Yale Climate Change & The Media: Strange Bedfellows? Climate Change Denial and Support for Geoengineering

"Potential benefits of geoengineering, despite attendant risks, appeal to some interests showing little concern for the seriousness of the climate change issue generally. What goes here?"

Boucher, Olivier; et al. (2013): Rethinking climate engineering categorization in the context of climate change mitigation and adaptation

Boucher, Olivier; Forster, Piers M.; Gruber, Nicolas; Ha-Duong, Minh; Lawrence, Mark G.; Lenton, Timothy M. et al. (2013): Rethinking climate engineering categorization in the context of climate change mitigation and adaptation. In WIREs Clim Change, pp. n/a. DOI 10.1002/wcc.261.

"We propose a new and more inclusive categorization into five different classes: anthropogenic emissions reductions (AER), territorial or domestic removal of atmospheric CO2 and other greenhouse gases (D‐GGR), trans‐territorial removal of atmospheric CO2 and other greenhouse gases (T‐GGR), regional to planetary targeted climate modification (TCM), and climate change adaptation measures (including local targeted climate and environmental modification, abbreviated CCAM)."

NERC: Geoengineering research should look at nutrient-poor waters

Summary of Hardman-Mountford, N. J.; et al (2013). "A new study suggests that plans to lock up carbon and slow climate change by adding nutrients to the ocean to encourage plankton growth might have been directed at the wrong places."

Hardman-Mountford, N. J.; et al (2013): Impacts of light shading and nutrient enrichment geo-engineering approaches on the productivity of a stratified, oligotrophic ocean ecosystem

Hardman-Mountford, N. J.; Polimene, L.; Hirata, T.; Brewin, R. J. W.; Aiken, J. (2013): Impacts of light shading and nutrient enrichment geo-engineering approaches on the productivity of a stratified, oligotrophic ocean ecosystem. In Journal of The Royal Society Interface 10 (89), p. 20130701. DOI 10.1098/rsif.2013.0701.

"In this paper, we investigate the relationship between light and nutrient availability on productivity in a stratified, oligotrophic subtropical ocean ecosystem using a one-dimensional water column model coupled to a multi-plankton ecosystem model, with the goal of elucidating potential impacts of these geo-engineering approaches on ecosystem production."

Tilmes, Simone; et al. (2013): The hydrological impact of geoengineering in the Geoengineering Model Intercomparison Project (GeoMIP)

Tilmes, Simone; Fasullo, John; Lamarque, Jean-Francois; Marsh, Daniel R.; Mills, Michael; Alterskjaer, Kari et al. (2013): The hydrological impact of geoengineering in the Geoengineering Model Intercomparison Project (GeoMIP). In J. Geophys. Res. Atmos. 118 (19), pp. 11,036. DOI 10.1002/jgrd.50868.

The hydrological impact of enhancing Earth's albedo by solar radiation management is investigated using simulations from 12 Earth System models contributing to the Geoengineering Model Intercomparison Project (GeoMIP).""
