Kravitz, Ben; et al. (2014): A multi-model assessment of regional climate disparities caused by solar geoengineering

Kravitz, Ben; MacMartin, Douglas G.; Robock, Alan; Rasch, Philip J.; Ricke, Katharine L.; Cole, Jason N S et al. (2014): A multi-model assessment of regional climate disparities caused by solar geoengineering. In: Environ. Res. Lett. 9 (7), S. 074013. DOI: 10.1088/1748-9326/9/7/074013.

„For the first time, we quantitatively evaluate the potential for regional disparities in a multi-model context using results from a model experiment that offsets the forcing from a quadrupling of CO2 via reduction in solar irradiance.“

Batten, S. D.; Gower, J. F. R. (2014): Did the iron fertilization near Haida Gwaii in 2012 affect the pelagic lower trophic level ecosystem?

Batten, S. D.; Gower, J. F. R. (2014): Did the iron fertilization near Haida Gwaii in 2012 affect the pelagic lower trophic level ecosystem? In: Journal of Plankton Research 36 (4), S. 925–932. DOI: 10.1093/plankt/fbu049.

„Deliberate fertilization of a patch of water west of Haida Gwaii, British Columbia, with iron sulphate and oxide occurred in summer 2012 and triggered a phytoplankton bloom strongly visible in satellite imagery in late August and detectable through September 2012.“

Dorn, R. I. (2014): Ants as a powerful biotic agent of olivine and plagioclase dissolution

Dorn, R. I. (2014): Ants as a powerful biotic agent of olivine and plagioclase dissolution. In Geology. DOI: 10.1130/G35825.1.

On enhanced weathering. „Ants, thus, have potential to provide clues on how to enhance contemporary carbon sequestration efforts to transform Ca-Mg silicates and CO2 into carbonate. Given that ants underwent a great iversification and biomass expansion over the Cenozoic, a speculative implication of this research is that ant enhancement of Ca-Mg silicate dissolution might have been an influence on Cenozoic cooling.“

WGC Blog: Is CDR ‘geoengineering’?

Guest Post- Noah Deich, MBA candidate, UC Berkeley. „Our society urgently needs as many reasonable, low-risk “carbon management” solutions to this problem as possible, and[nbsp]I think most[nbsp]would agree[nbsp]that planting trees, incentivizing carbon sequestering agricultural practices, and building biomass power plants with carbon capture are reasonable sounding options that we should[nbsp]consider[nbsp]alongside renewable energy, energy efficiency, and other GHG emission mitigation strategies in our fight against climate change.“

Berdahl, Mira (2014): Impacts of Volcanic Eruptions and Geoengineering on Arctic Climate

Berdahl, Mira (2014): Impacts of Volcanic Eruptions and Geoengineering on Arctic Climate. (A Dissertation submitted to the Graduate School-New Brunswick Rutgers). New Brunswick.

„Here I study the Arctic response to natural (volcanic eruptions) and potential anthropogenic (geoengineering) stratospheric sulfate aerosols. I use a regional climate model and global climate model output from two modeling intercomparison projects.“
