Bay Journal: Biochar could be the hot new thing in addressing Bay’s poultry litter

"West Virginia farmer Josh Frye raises chickens for a meat processor and sells most of their manure to nearby crop growers for use as fertilizer. But what he does with the rest of the manure could help tackle two big environmental problems: cutting back nutrient pollution in the Chesapeake Bay and reducing carbon emissions that accelerate global warming."

The Nation: Scientists propose new way to tackle climate change

"LOS ANGELES-Scientists have proposed a new way to tackle climate change by spraying sun-dimming chemicals into the Earth's atmosphere, according to a study published on other day. Scientists at Harvard and Yale universities have proposed using a technique known as Stratospheric Aerosol Injection (SAI), which they believe could cut the rate of global warming by half, according to a paper published in the journal Environmental Research Letters."

Gundersen, C.; et al. (2018): Growth response of environmental bacteria under exposure to nitramines from CO2-capture

Gundersen, C.; Andersen, T.; Vogt, R.; Allison, S. (2018): Growth response of environmental bacteria under exposure to nitramines from CO2-capture. In: International Journal of Greenhouse Gas Control 79, S. 248–251. DOI: 10.1016/j.ijggc.2018.11.003.

"Results from this study provide insight into important processes of bacterial response to nitramines that merit further investigation considering the ongoing implementation of CO2 capture technology."

Smith, W.; et al. (2018): Stratospheric aerosol injection tactics and costs in the first 15 years of deployment

Smith, W.; Wagner, G. (2018): Stratospheric aerosol injection tactics and costs in the first 15 years of deployment. In: Environ. Res. Lett. 13 (12), S. 124001. DOI: 10.1088/1748-9326/aae98d.

"We review the capabilities and costs of various lofting methods intended to deliver sulfates into the lower stratosphere. We lay out a future solar geoengineering deployment scenario of halving the increase in anthropogenic radiative forcing beginning 15 years hence, by deploying material to altitudes as high as ~20 km. After surveying an exhaustive list of potential deployment techniques, we settle upon an aircraft-based delivery system. Unlike the one prior comprehensive study on the topic (McClellan et al 2012 Environ. Res. Lett. 7 034019), we conclude that no existing aircraft design—even with extensive modifications—can reasonably fulfill this mission."

Gore, S.; et al. (2018): The potential environmental response to increasing ocean alkalinity for negative emissions

Gore, S.; Renforth, P.; Perkins, R. (2018): The potential environmental response to increasing ocean alkalinity for negative emissions. In: Mitig Adapt Strat Glob Change 47 (1), S. 199. DOI: 10.1007/s11027-018-9830-z.

"Increasing TA, however, did not significantly influence Corallina spp. primary productivity, respiration, or photophysiology. These results show that AOA may not be intrinsically detrimental for Corallina spp. and that AOA has the potential to lessen the impacts of ocean acidification. However, the experiment tested a single species within a controlled environment to constrain a specific unknown, the rate change of calcification, and additional work is required to understand the impact of AOA on other organisms, whole ecosystems, and the global carbon cycle."
