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

Helwegen, K.; Wieners, C.; Frank, J.; Dijkstra, H. (2019): Complementing CO2 emission reduction by Geoengineering might strongly enhance future welfare. In: Earth Syst. Dynam. Discuss., S. 1–24. DOI: 10.5194/esd-2019-5.

"We find that SRM has the potential to greatly enhance future welfare and should therefore be taken seriously as a policy option. However, if only SRM and no CO2 abatement is used, global warming is not stabilised and will exceed 2K. Therefore, even if successful, SRM cannot replace but only complement CO2 abatement. The optimal policy combines CO2 abatement and modest SRM and succeeds in keeping global warming below 2K."

The Conversation: Should we engineer the climate? A social scientist and natural scientist discuss

"Indeed, the spectre of climate engineering hung heavily over the recent United Nations climate conference in Katowice, COP24, having featured in several side events as negotiators agreed on how to implement the landmark 2015 Paris Agreement, but left many worried that it does not go far enough."

E-International Relations: The Emerging Politics of Geoengineering

"As droughts, forest fires and centennial floods become more commonplace, people around the world are feeling the consequences of climate change. As a result, some scientists are putting forth ideas to engineer the climate, collectively summarized as ‘Geoengineering’. But no matter whether one thinks of massive attempts to filter greenhouse gases from the air or planetary sheets of reflective material, geoengineering will have significant political effects."

Bala, G.; et al. (2018): Solar Geoengineering Research in India

Bala, G.; Gupta, A. (2018): Solar Geoengineering Research in India. In: Bulletin of the American Meteorological Society. DOI: 10.1175/BAMS-D-18-0122.1.

"We present here a brief account of the Indian scientific research into solar geoengineering. Climate modeling constitutes the major component of this geoengineering-relevant climate science research. The recent funding initiative by the Department of Science and Technology, the main funding agency for scientific research in India, in support of geoengineering modeling research and its efforts to bring natural, social and political scientists together for an evaluation solar geoengineering at meetings are also discussed. Finally, the directions for future scientific research into geoengineering in India are also discussed."
