Helwegen, K.; et al. (2019): Complementing CO2 emission reduction by solar radiation management might strongly enhance future welfare

Helwegen, K.; Wieners, C.; Frank, J.; Dijkstra, H. (2019): Complementing CO2 emission reduction by solar radiation management might strongly enhance future welfare. In: Earth Syst. Dynam. 10 (3), S. 453–472. DOI: 10.5194/esd-10-453-2019.

„Solar radiation management (SRM) has been proposed as a means to reduce global warming in spite of high greenhouse-gas concentrations and to lower the chance of warming-induced tipping points. However, SRM may cause economic damages and its feasibility is still uncertain. To investigate the trade-off between these (economic) gains and damages, we incorporate SRM into a stochastic dynamic integrated assessment model and perform the first rigorous cost–benefit analysis of sulfate-based SRM under uncertainty, treating warming-induced climate tipping and SRM failure as stochastic elements.“

Colvin, R.; et al. (2019): Learning from the Climate Change Debate to Avoid Polarisation on Negative Emissions

Colvin, R.; Kemp, L.; Talberg, A.; Castella, C. de; Downie, C.; Friel, S. et al. (2019): Learning from the Climate Change Debate to Avoid Polarisation on Negative Emissions. In: Environmental Communication 28, S. 1–13. DOI: 10.1080/17524032.2019.1630463.

„This paper identifies critical lessons from the climate change experience to guide how communications and engagement on negative emissions can be conducted to encourage functional public and policy discourse. Negative emissions technologies present a significant opportunity for limiting climate change, and are likely to be necessary to keep warming below 2°C.“

Forum for Climate Engineering: Researching at the Top of a Slippery Slope?

„Does researching geoengineering—specifically, stratospheric aerosol injection (SAI)—lead us onto a slippery slope, at the bottom of which awaits the deployment of a morally objectionable technology? Should we perhaps abandon research now on account of the possibility that we’ll slide down such a slope? In a recent publication, I argued that we should be cognizant of the possibility for research into SAI to lead to objectionable deployment scenarios.“

The Guardian: Most YouTube climate change videos oppose the consensus view

„The results for the search terms climate, climate change, climate science and global warming mostly reflected the scientific consensus view. Allgaier said this was because many contained excerpts from TV news programmes or documentaries. The same could not be said for the results of searches related to chemtrails, climate engineering, climate hacking, climate manipulation, climate modification and geoengineering.“

Jinnah, S.; et al. (2019): Governing Climate Engineering: A Proposal for Immediate Governance of Solar Radiation Management

Jinnah, S.; Nicholson, S.; Morrow, D.; Dove, Z.; Wapner, P.; Valdivia, W. et al. (2019): Governing Climate Engineering: A Proposal for Immediate Governance of Solar Radiation Management. In: Sustainability 11 (14), S. 3954. DOI: 10.3390/su11143954.

„Solar radiation management (SRM) technologies would reflect a small amount of incoming solar radiation back into space before the radiation can warm the planet. Although SRM may emerge as a useful component of a global response to climate change, there is also good reason for caution.“

Stenzel, F.; et al. (2019): Freshwater requirements of large-scale bioenergy plantations for limiting global warming to 1.5 °C

Stenzel, F.; Gerten, D.; Werner, C.; Jägermeyr, J. (2019): Freshwater requirements of large-scale bioenergy plantations for limiting global warming to 1.5 °C. In: Environ. Res. Lett. 14 (8), S. 84001. DOI: 10.1088/1748-9326/ab2b4b.

„This paper provides a first-order quantification of the biophysical potentials of BECCS as a negative emission technology contribution to reaching the 1.5 °C warming target, as constrained by associated water availabilities and requirements. Using a global biosphere model, we analyze the availability of freshwater for irrigation of BPs designed to meet the projected NEs to fulfill the 1.5 °C target, spatially explicitly on areas not reserved for ecosystem conservation or agriculture.“
