Science Daily: Thinking outside the box on climate mitigation

On Obersteiner, Michael; et al. (2018). "In a new commentary in the journal Nature Climate Change, IIASA researchers argue that a broader range of scenarios is needed to support international policymakers in the target of limiting climate change to under 2°C above pre-industrial levels, and to avoid potential negative environmental and social consequences of carbon dioxide removal on a massive scale."

Yamagata, Yoshiki; et al. (2018): Estimating water–food–ecosystem trade-offs for the global negative emission scenario (IPCC-RCP2.6)

Yamagata, Yoshiki; Hanasaki, Naota; Ito, Akihiko; Kinoshita, Tsuguki; Murakami, Daisuke; Zhou, Qian (2018): Estimating water–food–ecosystem trade-offs for the global negative emission scenario (IPCC-RCP2.6). In Sustain Sci 28, p. 113. DOI: 10.1007/s11625-017-0522-5.

"In this study, we assess the impact of BECCS deployment scenarios on the land systems including land use, water resources, and ecosystem services. Specifically, we assess three land-use scenarios to achieve the total amount of 3.3 GtC year−1 (annual negative emission level required for IPCC-RCP 2.6) emission reduction by growing bioenergy crops which requires huge use of global agricultural and forest lands and water."

Faran, Turaj S.; Olsson, Lennart (2018): Geoengineering. Neither economical, nor ethical—a risk–reward nexus analysis of carbon dioxide removal

Faran, Turaj S.; Olsson, Lennart (2018): Geoengineering. Neither economical, nor ethical—a risk–reward nexus analysis of carbon dioxide removal. In Int Environ Agreements 27 (12), p. 555. DOI: 10.1007/s10784-017-9383-8.

"Using the recently developed approach of risk–reward nexus (RRN) in the economics of innovation, we question the economic viability of CDR. The main argument is simple: if one uses the new framework of RRN in evaluating the innovations involved in the CDR branch of geoengineering, not only does one include more areas of risk but also one has to consider a broader base for distributing the rewards. Consequently, from RRN’s point of view, it would be less likely to find investing in CDR economically viable for the investor firms."

Eco Ri: Carbon-Capture Machines Part of Southern New England's 'Climate Change Moonshot' Initiative

"Graciela Chichilnisky has a machine that removes carbon dioxide from the atmosphere and she wants to build them in Rhode Island, Connecticut, and Massachusetts. The Massachusetts Institute of Technology-trained mathematician is a professor of economics at Columbia University and the CEO and co-founder of Global Thermostat, a New York City company that produces industrial-scale systems that collect carbon dioxide and sell it for commercial uses, such as carbonating soda, making plastic, or feeding plants."

Futurism: Our Climate Is Changing Rapidly. It’s Time to Talk About Geoengineering.

"Yet new versions of these planet-altering proposals persist. Many scientists hold on to geoengineering strategies as last-ditch efforts to save our future from ourselves, should all else fail."

Eureka Alert: Thinking outside the box on climate mitigation

On Obersteiner, Michael; et al. (2018). ""Many currently used emissions pathways assume that we can slowly decrease fossil fuel emissions today and make up for it later with heavy implementation of negative emissions technologies," says IIASA Ecosystems Services and Management Program Director Michael Obersteiner, lead author of the article. "This is a problem because it assumes we can put the burden on future generations--which is neither a realistic assumption nor is it morally acceptable from an intergenerational equity point of view.""

Blanco, Juan A. (2018): Managing Forest Soils for Carbon Sequestration. Insights From Modeling Forests Around the Globe

Blanco, Juan A. (2018): Managing Forest Soils for Carbon Sequestration. Insights From Modeling Forests Around the Globe. In : Soil Management and Climate Change: Elsevier, pp. 237–252.

"Soil carbon (C), a fundamental component of soil organic matter (SOM), is commonly recognized as one of the key parameters of soil quality. It has been linked to ecosystem productivity because it is a sensitive indicator for monitoring programs. It is a critical pool in the carbon cycle, and through its influence on many fundamental biological and chemical processes, it plays a pivotal role in nutrient release and availability. Through its role in soil aggregation, it influences soil porosity and thus gas exchange reactions and water storage and availability for plants and microorganisms. However, several processes can deplete or alter SOM in different ways (acid rain, atmospheric deposition, fire, intensive harvesting, etc.)."

Top10Toplist: Tinkering with the local weather

"To decide on something associated to local weather change, whether or not it's geoengineering or decreasing emissions, the method on the human aspect is mainly the identical: all of us have to sit down across the desk and conform to work collectively to make it work. Even when a method of geoengineering by miracle was to emerge tomorrow, a method that may assure a return to the preindustrial local weather with out unwanted effects, we are going to nonetheless must determine to check it and implement it collectively.

Point Reyes Light: Ranchers want to sequester more carbon

"The lawsuit against the Point Reyes National Seashore has stalled three park ranchers hoping to implement carbon sequestration practices to combat climate change. The practices range from the reduced tilling of grazing lands to the restoration of riparian areas, but a condition in the suit that prohibits new or expanded uses on ranchlands managed by the seashore could prevent the ranchers from adopting them."
