Kravitz, B., Robock, A., Boucher, O. et al. (2011), ‘The Geoengineering Model Intercomparison Project (GeoMIP)

Kravitz, B., Robock, A., Boucher, O. et al. (2011), ‘The Geoengineering Model Intercomparison Project (GeoMIP)’, Atmosph. Sci. Lett, 12/2: 162–167. DOI 10.1002/asl.316

"To evaluate the effects of stratospheric geoengineering with sulphate aerosols, we propose standard forcing scenarios to be applied to multiple climate models to compare their results and determine the robustness of their responses. Thus far, different modeling groups have used different forcing scenarios for both global warming and geoengineering, complicating the comparison of results. We recommend four experiments to explore the extent to which geoengineering might offset climate change projected in some of the Climate Model Intercomparison Project 5 experiments. These experiments focus on stratospheric aerosols, but future experiments under this framework may focus on different means of geoengineering."

Global Change: Climate geoengineering. Could we? Should we?

"Radical technological responses to counteract global warming are receiving increased attention as a possible policy option. But is geoengineering a potential safety net, a distraction or a dead end? Phil Williamson explores."

EUROCHAR - Development of technologies for long-term carbon sequestration

"In the context of climate change mitigation, technologies for removing the CO from the atmosphere are key challenges. The transfer of carbon from the atmosphere into useful carbon deposits is currently one promising option. Transferring biomass to carbon-rich materials with potential mega-scale application is an option to sequester carbon from plant material, taking it out of the short-term carbon cycle and therefore binding CO efficiently and even in a useful, productive, way into longer term non-atmospheric carbon pools. EuroChar will investigate carbon sequestration potentials that can be achieved by transforming plant biomass into charcoal (or Biochar) and add that to agricultural soils. Biochar production will be demonstrated using thermochemical (TC) or hydrothermal carbonization processes (HTC) that can produce energy and store 15 to 20% of the Carbon originally contained in the biomass. Detailed ISO-accredited whole Life Cycle Assessment will be carried out according to the International Reference Life Cycle Data System (ILCD) Handbook on LCA, for both TC and HTC production systems to evaluate the net Carbon sequestration capacity associated to Biochar production. Physico-chemical properties of Biochar will be analysed in a series of laboratory studies that will use standardized analytical protocols, and a specific phyto-toxicity test will be made using molecular approaches involving a model plant [...]"
