An, Chunjiang; Huang, Gordon (2015): Environmental concern on biochar. Capture, then what?

An, Chunjiang; Huang, Gordon (2015): Environmental concern on biochar. Capture, then what? In Environ Earth Sci. DOI: 10.1007/s12665-015-4741-8 

"Biochar tends to become the sink of soil pollutants. The changing soil environment can result in the release of toxic compounds from biochar in the long term. Biochar can be deactivated by clogged pores or decreasing sorption capacity."

Bozzi, E.; et al. (2015): Mimicking biochar-albedo feedback in complex Mediterranean agricultural landscapes

Bozzi, E.; Genesio, L.; Toscano, P.; Pieri, M.; Miglietta, F. (2015): Mimicking biochar-albedo feedback in complex Mediterranean agricultural landscapes. In Environ. Res. Lett. 10 (8), p. 84014–84014. DOI 10.1088/1748-9326/10/8/084014

"However, some side effects of large-scale biochar application need to be investigated. In particular a massive use of a low-reflecting material on large cropland areas may impact the climate via changes in surface albedo. Twelve years of MODIS-derived albedo data were analysed for three pairs of selected agricultural sites in central Italy."

Biochar Journal: Anatomy of a Field Trial: Wood-based Biochar and Compost Influences a Pacific Northwest Soil

"The discovery of elevated fertility of the Amazonian Terra Preta soils was widely reported in the news media starting in 2006, coinciding with the initial public awareness of the existential threat of climate change. Small groups of people worldwide seized on the idea of Terra Preta and biochar as a climate solution, and began to publicize and act on the promise of biochar."

Nova Next: The Coal That’s Good for the Climate

"But biochar has another trick up its sleeve. By retaining carbon even after combustion, it may not just help boost Diatta’s low yields. Some researchers believe it could be part of a solution to climate change, one of the most intractable problems of our era."

Morrow, David R. (2014): Ethical aspects of the mitigation obstruction argument against climate engineering research

Morrow, David R. (2014): Ethical aspects of the mitigation obstruction argument against climate engineering research. In Philosophical Transactions of the Royal Society 372 (2031). DOI 10.1098/rsta.2014.0062.

"Why would it be a bad thing if climate engineering research obstructed mitigation? If climate engineering promises to be effective enough, it might justify some reduction in mitigation. Climate policy portfolios involving sufficiently large or poorly planned reductions in mitigation, however, could lead to an outcome that would be worse than the portfolio that would be chosen in the absence of further climate engineering research."

Niemeier, U.; et al. (2013): Solar irradiance reduction via climate engineering - Impact of different techniques on the energy balance and the hydrological cycle.

Niemeier, U.; Schmidt, H.; Alterskjaer, K.; Kristjánsson, J. E. (2013): Solar irradiance reduction via climate engineering - Impact of different techniques on the energy balance and the hydrological cycle. In J. Geophys. Res. Atmos., pp. n/a. DOI 10.1002/2013JD020445

"Different techniques of solar radiation management (SRM) have been suggested to counteract global warming, among them the injection of sulfur into the stratosphere, mirrors in space, and marine cloud brightening through artificial emissions of sea salt. This study focuses on to what extent climate impacts of these three methods would be different."
