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."

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."

Proctor, J.; et al. (2018): Estimating global agricultural effects of geoengineering using volcanic eruptions

Proctor, J.; Hsiang, S.; Burney, J.; Burke, M.; Schlenker, W. (2018): Estimating global agricultural effects of geoengineering using volcanic eruptions. In: Nature. DOI: 10.1038/s41586-018-0417-3.

"Here we use the volcanic eruptions that inspired modern solar radiation management proposals as natural experiments to provide the first estimates, to our knowledge, of how the stratospheric sulfate aerosols created by the eruptions of El Chichón and Mount Pinatubo altered the quantity and quality of global sunlight, and how these changes in sunlight affected global crop yields."

Berkeley News: Blocking sunlight to cool Earth won’t reduce crop damage from global warming

"Injecting particles into the atmosphere to cool the planet and counter the warming effects of climate change would do nothing to offset the crop damage from rising global temperatures, according to a new analysis by University of California, Berkeley, researchers."

Nature: Glacier geoengineering needs lawyers too

"Proposals such as those of John Moore and colleagues (Nature 555, 303–305; 2018) for Antarctic glacier geoengineering understate the legal challenges presented by the Antarctic Treaty System (ATS). This system is crucial to Antarctic governance, but faces considerable geopolitical pressure (Nature 558, 161; 2018). It is essential that any activities affecting the Antarctic ecosystem properly engage with the ATS from the outset."
