Fuss, Sabine; et al. (2018): Negative emissions—Part 2. Costs, potentials and side effects

Fuss, Sabine; Lamb, William F.; Callaghan, Max W.; Hilaire, Jérôme; Creutzig, Felix; Amann, Thorben et al. (2018): Negative emissions—Part 2. Costs, potentials and side effects. In Environ. Res. Lett. 13 (6), p. 63002. DOI: 10.1088/1748-9326/aabf9f.

"The most recent IPCC assessment has shown an important role for negative emissions technologies (NETs) in limiting global warming to 2 °C cost-effectively. However, a bottom-up, systematic, reproducible, and transparent literature assessment of the different options to remove CO2 from the atmosphere is currently missing. In part 1 of this three-part review on NETs, we assemble a comprehensive set of the relevant literature so far published, focusing on seven technologies: bioenergy with carbon capture and storage (BECCS), afforestation and reforestation, direct air carbon capture and storage (DACCS), enhanced weathering, ocean fertilisation, biochar, and soil carbon sequestration."

Minx, Jan C.; et al. (2018): Negative emissions—Part 1. Research landscape and synthesis

Minx, Jan C.; Lamb, William F.; Callaghan, Max W.; Fuss, Sabine; Hilaire, Jérôme; Creutzig, Felix et al. (2018): Negative emissions—Part 1. Research landscape and synthesis. In Environ. Res. Lett. 13 (6), p. 63001. DOI: 10.1088/1748-9326/aabf9b.

"Here, we synthesize a comprehensive body of NETs literature, using scientometric tools and performing an in-depth assessment of the quantitative and qualitative evidence therein. We clarify the role of NETs in climate change mitigation scenarios, their ethical implications, as well as the challenges involved in bringing the various NETs to the market and scaling them up in time."

Forbes: Ask Ethan: Can We Build A Sun Screen To Combat Global Climate Change?

"Global climate change is one of the most pressing long-term issues facing humanity today. The science is abundantly clear on what's happening and why: the Earth is getting warmer, human-caused emission of heat-trapping greenhouse gases is the reason, and the concentration of these gases only continues to rise, unabated, over time. While there are a great many calls to reduce emissions, capture carbon, and move away from fossil fuels, there's little that's effectively been done."

Gannon, Kate Elizabeth; Hulme, Mike (2018): Geoengineering at the “Edge of the World”. Exploring perceptions of ocean fertilisation through the Haida Salmon Restoration Corporation

Gannon, Kate Elizabeth; Hulme, Mike (2018): Geoengineering at the “Edge of the World”. Exploring perceptions of ocean fertilisation through the Haida Salmon Restoration Corporation. In Geo: Geography and Environment 5 (1), e00054. DOI: 10.1002/geo2.54.

"More broadly, the controversy illustrated long‐standing arguments about the desirability and feasibility of ocean fertilisation as a geoengineering response to the threat of anthropogenic climate change. Using the HSRC case, this paper reports a novel situated study of public perceptions of geoengineering that combines ethnographic engagement with Q‐methodology."

Hoffmann Centre: Betting on BECCS? Exploring Land-Based Negative Emissions Technologies

"The workshop explored the role of negative emissions, particularly bioenergy with carbon capture and storage (BECCS), in achieving the UNFCCC Paris Agreement goals. Significant deployment of BECCS is common to most Paris-compliant emissions reduction pathways, but raises important questions for policymakers."

Daily Guardian: Geoengineering and climate change

"As pointed out in the book of Pulitzer Prize-winning author Thomas Freidman, Hot, Flat and Crowded, our climate and energy crisis are interconnected – we can’t solve one without addressing the other. As ordinary citizens, we can do a big part in energy conservation and by changing our lifestyle that it is not energy expensive."

Tilmes, Simone; et al. (2018): CESM1(WACCM) Stratospheric Aerosol Geoengineering Large Ensemble (GLENS) Project

Tilmes, Simone; Richter, Jadwiga H.; Kravitz, Ben; MacMartin, Douglas G.; Mills, Michael J.; Simpson, Isla R. et al. (2018): CESM1(WACCM) Stratospheric Aerosol Geoengineering Large Ensemble (GLENS) Project. In Bulletin of the American Meteorological Society. DOI: 10.1175/BAMS-D-17-0267.1.

"This paper describes the stratospheric aerosol geoengineering large ensemble (GLENS) project, which promotes the use of a unique model dataset, performed with the Community Earth System Model, with the Whole Atmosphere Community Climate Model as its atmospheric component (CESM1(WACCM)), to investigate global and regional impacts of geoengineering. The performed simulations were designed to achieve multiple simultaneous climate goals, by strategically placing sulfur injections at four different locations in the stratosphere, unlike many earlier studies that targeted globally averaged surface temperature by placing injections in regions at or around the equator."

Eastham, Sebastian D.; et al. (2018): Quantifying the impact of sulfate geoengineering on mortality from air quality and UV-B exposure

Eastham, Sebastian D.; Weisenstein, Debra K.; Keith, David W.; Barrett, Steven R.H. (2018): Quantifying the impact of sulfate geoengineering on mortality from air quality and UV-B exposure. In Atmospheric Environment. DOI: 10.1016/j.atmosenv.2018.05.047.

"Using a chemistry-transport model, we quantify the steady-state response of three public health risks to 1 °C global mean surface cooling. We separate impacts into those which are “radiative forcing-driven”, associated with climate change “reversal” through modification of global radiative forcing, and those “direct impacts” associated uniquely with using sulfate geoengineering to achieve this. We find that the direct (non-radiative forcing driven) impact is a decrease in global mortality of ∼13,000 annually."

Bellamy, Rob (2018): Incentivize negative emissions responsibly

Bellamy, Rob (2018): Incentivize negative emissions responsibly. In Nat. Energy 534, p. 631. DOI: 10.1038/s41560-018-0156-6.

"Nation states need to incentivize negative emissions technologies if they are to take the decarbonization of whole energy systems seriously. This incentivization must account for public values and interests in relation to which technologies to incentivize, how they should be incentivized and how they should be governed once incentivized."
