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."

New York Times: A Fresh Look at Iron, Plankton, Carbon, Salmon and Ocean Engineering

On iron fertilization. "One lesson is that while privately financed science is playing a growing role in advancing knowledge, proprietary and legal issues can limit vital transparency."

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 I think most would agree that planting trees, incentivizing carbon sequestering agricultural practices, and building biomass power plants with carbon capture are reasonable sounding options that we should consider 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."

MacKerron, Gordon (2014): Costs and economics of geoengineering

MacKerron, Gordon (2014): Costs and economics of geoengineering (CGG Working Papers, 13).

"The starting point here is the frequently observed phenomenon of ‘appraisal optimism’ or optimism bias (UK Treasury 2013)– the escalation of the costs of a new technology well beyond original expectations. These escalations have been frequent – virtually pervasive – where technologies are novel and/or the scale of activity has been large (‘megaprojects’), and they have overwhelmed any learning or economy of scale effects that have, in other technologies or products, acted to reduce costs over time."

Klepper, G.; Rickels, W. (2014): Climate Engineering: Economic Considerations and Research Challenges. In Review of Environmental Economics and Policy 8 (2), pp. 270–289. DOI: 10.1093/reep/reu010.

"Thus we argue that a research strategy is needed that focuses on increasing our basic understanding of the earth system and conducting comprehensive assessments of the risk(s) associated with both climate change and the deployment of climate engineering."
