POST (2017): Greenhouse Gas Removal. UK Parliamentary Office of Science and Technology (POSTnotes, 549).
„The 2015 Paris Agreement called for a balance between sources of Greenhouse Gas (GHG) emissions and their removal by 2100 to halt global temperature rise. This POSTnote explains why Greenhouse Gas Removal (GGR) techniques may be required to achieve this goal, outlines the benefits of and concerns about them, and considers policy options.“
„To geochemist Greg Rau, the future looks like a seaside power plant. More specifically, it looks like a biomass combustion plant that’s actually carbon-negative because the CO2 emissions are dissolved and captured in a mix of seawater and alkaline minerals through a process called chemical weathering. Why does Rau want to see that plant erected, perhaps along the coast near UC Santa Cruz, where he works? Because he believes that energy generation can solve the problems created by energy generation. He believes that this is how you begin to turn back 150 years of carbon dioxide emissions before sea level rise engulfs the landscape and would-be power plant operators have to look for new real estate.“

„This paper examines how the meanings of geoengineering experimentation, specifically SAI field trials, are reconfigured in the deliberation of the lay public. To this end, we conducted focus groups with Japanese citizens in June 2015 on the geoengineering concept and SAI field trials.“
Fischer, Severin (2017): Climate Policy After Paris: Inconvenient Truths. Edited by Christian Nünlist (CSS Analyses in Security Policy, 203).
„The Paris Agreement of December 2015 fundamentally realigned the structures of international climate policy. At the same time, global targets and national measures are diverging. One direct implication is the need to consider new technology options.“

Laakso, Anton; Korhonen, Hannele; Romakkaniemi, Sami; Kokkola, Harri (2017): Radiative and climate effects of stratospheric sulfur geoengineering using seasonally varying injection areas. In: Atmos. Chem. Phys. Discuss., S. 1–25. DOI: 10.5194/acp-2017-107.
„In this study we employ alternative aerosol injection scenarios to investigate if the resulting radiative forcing can be optimized to be zonally more uniform without decreasing the global efficacy. We used a global aerosol-climate model together with an Earth system model to study the radiative and climate effects of stratospheric sulfur injection scenarios with different injection areas. According to our simulations, varying the SO2 injection area seasonally would result in a similar global mean cooling effect as injecting SO2 to the equator, but with a more uniform zonal distribution of shortwave radiative forcing.„
„Countries will need far more capacity to capture carbon and store it to reach their emissions reductions goals as outlined in the Paris agreement, study concludes.“

„This article provides a unique intercontinental mapping of the prioritization of BECCS for the long term transition of the electricity supply sector. Based on survey responses from 711 UN climate change conference delegates, the article reports the low prioritization of BECCS relative to alternative technologies, indicating an urgent need for studies of the socio-political preconditions for large-scale BECCS deployment.“

„Geoengineering technologies like Solar Radiation Management have the potential to mitigate risks from climate change, while at the same time posing risks of their own. The current lack of international norms on acceptable research practices may well be holding back safe exploration of climate engineering options.“
