Wolf, Martin J.; et al. (2020): A biogenic secondary organic aerosol source of cirrus ice nucleating particles

Wolf, Martin J.; Zhang, Yue; Zawadowicz, Maria A.; Goodell, Megan; Froyd, Karl; Freney, Evelyn et al. (2020): A biogenic secondary organic aerosol source of cirrus ice nucleating particles. In Nat Comms 11 (1), p. 4834. DOI: 10.1038/s41467-020-18424-6.

"Atmospheric ice nucleating particles (INPs) influence global climate by altering cloud formation, lifetime, and precipitation efficiency. The role of secondary organic aerosol (SOA) material as a source of INPs in the ambient atmosphere has not been well defined. Here, we demonstrate the potential for biogenic SOA to activate as depositional INPs in the upper troposphere by combining field measurements with laboratory experiments."

Yang, Huiyi; et al. (2020): South India projected to be susceptible to high future groundnut failure rates for future climate change and geo-engineered scenarios

Yang, Huiyi; Dobbie, Steven; Ramirez-Villegas, Julian; Chen, Bing; Qiu, Shaojun; Ghosh, Sat; Challinor, Andy (2020): South India projected to be susceptible to high future groundnut failure rates for future climate change and geo-engineered scenarios. In The Science of the Total Environment 747, p. 141240. DOI: 10.1016/j.scitotenv.2020.141240.

"With an increase in global mean temperature predicted for this century accompanied by more frequent extremes, will farming communities need to brace for increased crop failures and hardship? Solar dimming climate geoengineering has been proposed as a possible solution to combat rising global temperature but what effect will it or other climate related adaptation have on crop failures? We performed a crop modelling study using future climate and geoengineering projections to investigate these questions."

Buck, Holly; et al. (2020): Pandemic politics—lessons for solar geoengineering

Buck, Holly; Geden, Oliver; Sugiyama, Masahiro; Corry, Olaf (2020): Pandemic politics—lessons for solar geoengineering. In Commun Earth Environ 1 (1), pp. 1–4. DOI: 10.1038/s43247-020-00018-1.

"Responses to the COVID-19 emergency have exposed break-points at the interface of science, media, and policy. We summarize five lessons that should be heeded if climate change ever enters a state of emergency perceived to warrant stratospheric aerosol injection."
