Pfrommer, T. (2018): Diverging Regional Climate Preferences and the Assessment of Solar Geoengineering

Pfrommer, T. (2018): Diverging Regional Climate Preferences and the Assessment of Solar Geoengineering. Heidelberg (Discussion Paper Series, 0654). DOI: 10.11588/heidok.00025204

"Solar Geoengineering (SG) is a set of potential technologies to counteract climate change. While SG can only imperfectly compensate for temperature changes at the regional level, studies assessing regional SG impacts indicated so far that regional temperature disparities from SG may not be as severe as previously thought. A shortcoming of that literature is its assumption that regions’ temperature preferences correspond to some historic baseline climate. I extend the main framework for examining regional SG impacts by allowing for regions to have temperature preferences diverging from the baseline climate, showing that the impact of these diverging preferences can be split into two components."

C2G2: What we don’t know about geoengineering and biodiversity

"On Montreal’s hottest day since records began, we met with leading technical experts to the Convention on Biological Diversity (CBD), to present a new Technical Briefing Paper exploring what we do and don’t know about geoengineering and biodiversity."

Politico: Europe mulls stripping carbon from the skies

"Carbon removal schemes range from planting lots of trees to more experimental methods to artificially suck up carbon. Some of those ideas are grouped under the label geoengineering, something that’s long been anathema because of fears that overt tinkering with the planet could lead to catastrophe."

Phys.org: Scientists find way to make mineral which can remove CO2 from atmosphere

"Scientists have found a rapid way of producing magnesite, a mineral which stores carbon dioxide. If this can be developed to an industrial scale, it opens the door to removing CO2 from the atmosphere for long-term storage."

Scientists have found a rapid way of producing magnesite, a mineral which stores carbon dioxide. If this can be developed to an industrial scale, it opens the door to removing CO2 from the atmosphere for long-term storage, thus countering the global warming effect of atmospheric CO2. This work is presented at the Goldschmidt conference in Boston.

Schulz, I.; et al. (2018): Remarkable structural resistance of a nanoflagellate-dominated plankton community to iron fertilization during the Southern Ocean experiment LOHAFEX

Schulz, I.; Montresor, M.; Klaas, C.; Assmy, P.; Wolzenburg, S.; Gauns, M. et al. (2018): Remarkable structural resistance of a nanoflagellate-dominated plankton community to iron fertilization during the Southern Ocean experiment LOHAFEX. In: Mar. Ecol. Prog. Ser. 601, S. 77–95. DOI: 10.3354/meps12685.

"We attribute the unusually high biomass attained and maintained by ANF to the absence of their grazers, the salps, and to constraints on protozooplankton grazers by heavy predation exerted by the large copepod stock. The resistance to change of the ecosystem structure over 38 d after fertilization, indicated by homogeneity at regional and temporal scales, suggests that it was locked into a stable, mature state that had evolved in the course of the seasonal cycle. The LOHAFEX bloom provides a case study of a resistant/robust dynamic equilibrium between auto- and heterotrophic ecosystem components resulting in low vertical flux both inside and outside the patch despite high biomass levels."

Heyen, D.; et al. (2018): Strategic implications of counter-geoengineering

Heyen, D.; Horton, J.; Moreno C. (2018): Strategic implications of counter-geoengineering. Clash or cooperation. Munich: CESifo Center for Economic Studies & Ifo Institute (CESifo working paper Category 10, Energy and climate economics, no. 7180). Online verfügbar unter http://www.cesifo-group.de/ifoHome/publications/docbase/DocBase_Content/WP/WP-CESifo_Working_Papers/wp-cesifo-2018/wp-cesifo-2018-07/12012018007180.html.

"We analyze whether the threat of counter-geoengineering technologies capable of negating the climatic effects of solar geoengineering can overcome the free-driver problem and tilt the game in favor of international cooperation. Our game-theoretical model of asymmetric countries allows for a rigorous analysis of the strategic interaction surrounding solar geoengineering and counter-geoengineering. "

Hamilton, D. S.; et al. (2018): Reassessment of pre-industrial fire emissions strongly affects anthropogenic aerosol forcing

Hamilton, D. S.; Hantson, S.; Scott, C. E.; Kaplan, J. O.; Pringle, K. J.; Nieradzik, L. P. et al. (2018): Reassessment of pre-industrial fire emissions strongly affects anthropogenic aerosol forcing. In: nature communications 9 (1), S. 3182. DOI: 10.1038/s41467-018-05592-9.

"Uncertainty in pre-industrial natural aerosol emissions is a major component of the overall uncertainty in the radiative forcing of climate. Improved characterisation of natural emissions and their radiative effects can therefore increase the accuracy of global climate model projections. Here we show that revised assumptions about pre-industrial fire activity result in significantly increased aerosol concentrations in the pre-industrial atmosphere."
