Project: Harvard grants for solar geoengineering

"The Keith Group is grateful to have been the lead recipient of three grants from internal Harvard programs over the past few months: The Star Family Challenge for Scientific Research, The Weatherhead Initiative Research Cluster in International Affairs, and The Harvard Climate Solutions Fund. We thank these generous programs for funding research on a variety of important topics related to solar geoengineering. Grants with a total value of 450 $k (without overhead) will enable researchers to address key scientific and governance questions surrounding solar geoengineering:"

Cao, Long; et al. (2016): Simulated long-term climate response to idealized solar geoengineering

Cao, Long; Duan, Lei; Bala, Govindasamy; Caldeira, Ken (2016): Simulated long-term climate response to idealized solar geoengineering. In Geophys. Res. Lett., pp. n/a-n/a. DOI 10.1002/2016GL068079.

"Here we use the HadCM3L model to conduct a 1000-year sunshade geoengineering simulation in which solar irradiance is uniformly reduced by 4% to approximately offset global mean warming from an abrupt quadrupling of atmospheric CO2. During the 1000-year period, modeled global climate, including temperature, hydrological cycle, and ocean circulation of the high-CO2 simulation departs substantially from that of the control preindustrial simulation, whereas the climate of the geoengineering simulation remains much closer to that of the preindustrial state with little drift."

UMich Blog: It Time to Get Serious About Geoengineering?

Article about iron fertilization of LOHAFEX. "As the RV Polarstern crept out of Cape Town Harbor, Victor Smetacek gathered his 49-member crew on deck to watch the lights of the city slowly fade from view. It was January 7, 2009, a cool South African summer evening. And after nearly four years of painstaking preparations, they had finally begun LOHAFEX, the longest and most comprehensive ocean iron fertilization experiment ever attempted."

Oceanbites: A cloudy future for climate engineering

Blog article on Tjiputra, J. F., A. Grini, and H. Lee (2016). "A team of scientists based in Norway modeled the response of the carbon cycle to aerosol injection compared with the normal projected climate warming. The carbon cycle could either help or hurt geoengineering efforts by regulating the concentration of CO2 (a greenhouse gas) in the atmosphere."

Morrow, David R.; Svoboda, Toby (2016): Geoengineering and Non-Ideal Theory

Morrow, David R.; Svoboda, Toby (2016): Geoengineering and Non-Ideal Theory. In PAQ (Public Affairs Quarterly) 30 (1), pp. 83–102.

"Some acts are beyond the pale: they ought never to be done, except perhaps in the most dire emergencies. Other acts are wrong in a less stringent sense: they would never be done in an ideal world, but might be permissible in nonideal circumstances. Deliberate, large-scale modifications of earth systems to counteract or reduce the effects of climate change, known as geoengineering or climate engineering, arguably belong to one of these two types—but which one?"

Gong, Pi-Hai; et al. (2014): [Estimation and experiment of carbon sequestration by oysters attached to the enhancement artificial reefs in Laizhou Bay, Shandong, China]

Chinese paper on carbon sequestration. Title and abstract hav not been translated until now. "Through sampling investigation of fouling organisms on the enhancement artificial reefs set up in Laizhou Bay, it was proved that oyster (Ostrea plicatula) was the dominant fouling species. Therefore the dry mass of shell (Ms), total fresh mass (Mt) and thickness (T) of oyster attached on the reefs were analyzed. The results showed that the Mt and Ms presented seasonal variation (P < 0.01), that is, the values were the lowest in April and the highest in December."
