Forests News: Q&A: Lessons from China for forest landscape restoration

"The basic principle is that increasing biomass in landscapes – and that can be trees, shrubs or even grasses, like bamboo – generates multiple environmental benefits such as carbon capture, water purification and flood control."

Mohan, V. (2016): Combining Bioenergy with Carbon Capture and Storage (BECCS) - A Review

Mohan, V. (2016): Combining Bioenergy with Carbon Capture and Storage (BECCS) - A Review. In : Near Surface Geoscience 2016 - 22nd European Meeting of Environmental and Engineering Geophysics. Barcelona, Spain: EAGE Publications BVNetherlands (Proceedings).

"This paper provides a comprehensive overview of the technologies and issues associated with BECCS and highlight the implicated challenges related with the incentive policies based on an assessment of the net impact on emissions achievable. Further, the need for internationally compatible accounting policy incorporating all emissions generated by BECCS over its lifecycle is discussed."

Markusson, Nils; et al. (2016): Contrasting medium and genre on Wikipedia to open up the dominating definition and classification of geoengineering

Markusson, Nils; Venturini, Tommaso; Laniado, David; Kaltenbrunner, Andreas (2016): Contrasting medium and genre on Wikipedia to open up the dominating definition and classification of geoengineering. In Big Data & Society 3 (2). DOI 10.1177/2053951716666102.

"We analyse the representation of geoengineering on Wikipedia as a way of opening up this dominating, if contested, model for further debate. We achieve this by contrasting the dominating model as presented in the encyclopaedic article texts with the patterns of hyper-link associations between the articles. Two datasets were created tracing the geoengineering construct on Wikipedia, shedding light on its boundary with its context, as well as on its internal structure. The analysis shows that the geoengineering category tends to be associated on Wikipedia primarily with atmospheric solar radiation management rather than land-based carbon dioxide removal type technologies."

Market Mogul: Engineering The Earth, Or How To Fight Global Warming

"Geoengineering is not an adaptation strategy but is a particular form of climate change, which involves the deliberate intervention into the Earth’s natural systems to counteract the greenhouse effect. This method focuses on solar radiation management which involves the reflection of sunlight back into space, using techniques such as creating a stratospheric veil of aerosol particles to reflect sunlight, or releasing trillions of mirrors into space to deflect the sun’s rays, forming a 100,000 square mile “sun shade.”"

Medium: Scientists Focused on Geoengineering Challenge the Inevitability of Multi-Millennial Global Warming

"I encourage anyone interested in climate change science and policy to explore the rich discussion below about geoengineering, in this case mainly focused on managing incoming solar radiation to counter CO2-driven global warming."

Our Energy Policy: Is Bioenergy with CCS Critical to the Paris Agreement?

"While proponents contend that BECCS might effectuate sequestration up to 17 gigatons of carbon dioxide annually by 2100, questions about the technology’s economic viability and risks abound."

Davis, Nicholas A.; et al. (2016): Changes in the width of the tropical belt due to simple radiative forcing changes in the GeoMIP simulations

Davis, Nicholas A.; Seidel, Dian J.; Birner, Thomas; Davis, Sean M.; Tilmes, Simone (2016): Changes in the width of the tropical belt due to simple radiative forcing changes in the GeoMIP simulations. In Atmos. Chem. Phys. 16 (15), pp. 10083–10095. DOI 10.5194/acp-16-10083-2016.

"To shed light on robust processes associated with tropical expansion, here we examine how the tropical belt width, as measured by the Hadley cell edges, responds to simplified forcings in the Geoengineering Model Intercomparison Project (GeoMIP). The tropical belt expands in response to a quadrupling of atmospheric carbon dioxide concentrations and contracts in response to a reduction in the solar constant, with a range of a factor of 3 in the response among nine models."

The Japan Times: Record heat in 2016 nudges Earth toward Paris ceiling

"Draft documents for the 2018 report by the IPCC also mention more radical solutions, such as spraying chemicals into the upper atmosphere to dim sunlight through “geo-engineering.”"

Pacific Standard: Bracing Ourselves for the Climate Tipping Point

"“An interesting question is the extent to which the scoping team will want to include solar geo-engineering, which is probably the most feasible method of stabilizing at 1.5 degrees Celsius, at least in the short term,” climate scientist Ken Caldeira said by email."
