„A relatively small, but growing, voice is suggesting a technological fix to these problems: active climate intervention. This is the audacious idea of intentionally modifying the climate to compensate for the carbon emissions that we seem unwilling to curtail.“
„Today, some scientists are singing a very similar tune. But what technologies do we have at our disposal to counter climate change? Have we advanced geoengineering in the last half-century? Is geoengineering safe or even ethical?“
„However, along with acceptance of a changing climate, there is a yearning for a technological fix, a silver bullet that will make things right.“
„While no one knows for sure which [nbsp]geoengineering proposals offer the most promise, I would argue that they should at least be more openly debated and further researched as a possible climate solution (particularly for a crisis situation where the reduction in CO2 needs to be immediate).“
Critical response to Kahan, D. M.; et al. (2015). „I will argue here that this experiment achieved no such result because the premise was wrong. Specifically, the information on geoengineering that was presented to the study participants (in the form of a fictional newspaper article) bears no relation to mainstream scientific opinion on geoengineering nor, even, to the opinions of advocates of geoengineering.„
„In a collaboration with Rutgers Business School, Distinguished Professor Paul Falkowski talks about two interventions as business opportunities for reducing the effects of carbon dioxide build-up in the atmosphere.“
„Serious research outside of these limits has been a taboo because of the serious risks this may pose for ecosystems and society. However, two recent publications are breaking the ice and bringing the discussion of field experiments into the limelight of the scientific community.“

„In terms of policy interventions, this means that rather than pursuing individual actors to mitigate counter to their
immediate personal interest, the task becomes one of reining in those who want to pursue climate engineering of their own volition.“
Article on Sanchez, Daniel L.; et al. (2015).[nbsp] „By capturing carbon from burning biomass – termed bioenergy with carbon capture and sequestration (BECCS) – power generators could become carbon-negative even while retaining gas- or coal-burning plants with carbon capture technology.“
Sanchez, Daniel L.; Nelson, James H.; Johnston, Josiah; Mileva, Ana; Kammen, Daniel M. (2015): Biomass enables the transition to a carbon-negative power system across western North America. In Nature Climate change 5 (3), pp. 230–234. DOI 10.1038/nclimate2488.
„Here, we explore the economic and deployment implications for BECCS in the electricity system of western North America under aggressive (pre-2050) time frames and carbon emissions limitations, with rich technology representation and physical constraints. We show that BECCS, combined with aggressive renewable deployment and fossil-fuel emission reductions, can enable a carbon-negative power system in western North America by 2050 with up to 145% emissions reduction from 1990 levels.“
