wtop: What Earth Day means when humans possess planet-shaping powers

"For nearly 50 years, Earth Day has provided an opportunity for people across the globe to come together and rally in support of the natural world. While the specific challenges have varied, the goal has remained more or less the same: to protect the rich, biological world that the current generation has inherited from being overwhelmed by the influences of humanity."

Wei, Liren; et al. (2018): Global streamflow and flood response to stratospheric aerosol geoengineering

Wei, Liren; Ji, Duoying; Miao, Chiyuan; Moore, John C. (2018): Global streamflow and flood response to stratospheric aerosol geoengineering. In Atmos. Chem. Phys. Discuss., pp. 1–38. DOI: 10.5194/acp-2018-338.

"Flood risk is projected to increase under projections of future warming climates due to an enhanced hydrological cycle. Solar geoengineering is known to reduce precipitation and slowdown the hydrological cycle, and may be therefore be expected to offset increased flood risk. We examine this hypothesis using streamflow and river discharge responses to the representative concentration pathway RCP4.5 and Geoengineering Model Intercomparison Project (GeoMIP) G4 experiments."

Algea Industry Magazine: Algae with Bioenergy with Carbon Capture and Storage

"The University of Hawaii at Hilo announced that in affiliation with Duke and Cornell Universities, researchers have authored a study that suggests making croplands more efficient through algae production could unlock an important negative emission technology to combat climate change. Their research, “Integrating Algae with Bioenergy Carbon Capture and Storage (ABECCS) Increases Sustainability,” is funded by a U.S. Department of Energy award and was recently published in the journal Earth’s Future."

Ecologist: Climate change - is it now time for extreme measures?

"Proponents argue that geoengineering may be the only way of preventing climatic harms in the absence of substantial emissions reductions. But the consequences could be global, fatal, unintended and uncontrollable."

CBC: Capturing carbon and the cold from outer space: TED speakers explore how to save the planet

"Wilcox said there are about eight companies around the world that are beginning to capture carbon and harvest it for energy — including Calgary-based Carbon Engineering, which has a plant in Squamish, B.C. The costs to capture carbon are still too high to make the technology ubiquitous enough to have a meaningful impact, however."

McLaren, Duncan P. (2018): In a broken world. Towards an ethics of repair in the Anthropocene

McLaren, Duncan P. (2018): In a broken world. Towards an ethics of repair in the Anthropocene. In The Anthropocene Review 12 (11), 205301961876721. DOI: 10.1177/2053019618767211.

"With the power to break Earth Systems comes responsibility to care for them, and arguably to repair them. Climate geoengineering is one possible approach. But repair is under-researched and underspecified in this context. In a first attempt to establish basic principles for the obligations of repair in the Anthropocene, five disciplines of repair are briefly reviewed: reconstruction of historic buildings; remediation of human bodies; restoration of ecosystems; reconfiguration of cultural materials and artifacts; and reconciliation of broken relationships. In each case ethical practices and debates are described to help identify key themes and challenges in understanding repair."

Oliveira Garcia, Wagner de; et al. (2018): Increasing biomass demand enlarges negative forest nutrient budget areas in wood export regions

Oliveira Garcia, Wagner de; Amann, Thorben; Hartmann, Jens (2018): Increasing biomass demand enlarges negative forest nutrient budget areas in wood export regions. In Scientific reports 8 (1), p. 5280. DOI: 10.1038/s41598-018-22728-5.

"Energy production from biomass is one of the adopted strategies in different European countries to limit global warming to within the 1.5–2° targets after the 2015 UN climate agreement. This will motivate enhanced forest harvest rates and whole tree harvest to supply the increasing biomass demand. Negative nutrient budgets for certain timberland areas where geogenic nutrient supply cannot cope with harvesting rates will be one consequence. A spatially explicit analysis for a U.S. timberland area of 33,570 km2 reveals that for a minimum nutrient loss and supply scenario, negative nutrient budgets occur in 17, 20, 16, and almost 94% of the studied areas for Ca, K, Mg, and P, respectively."
