Singh, M.; et al. (2020): Fingerprint of volcanic forcing on the ENSO-Indian monsoon coupling

Singh, M.; Krishnan, R.; Goswami, B.; Choudhury, A. D.; Swapna, P.; Vellore, R. et al. (2020): Fingerprint of volcanic forcing on the ENSO-Indian monsoon coupling. In Science Advances 6 (38). DOI: 10.1126/sciadv.aba8164.

"Here, we investigate how LVEs influence the nonlinear behavior of the ENSO and IM dynamical systems using historical data, 25 paleoclimate reconstructions, last-millennium climate simulations, large-ensemble targeted climate sensitivity experiments, and advanced analysis techniques."

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."

Visioni, Daniele; et al. (2020): Reduced Poleward Transport Due to Stratospheric Heating Under Stratospheric Aerosols Geoengineering

Visioni, Daniele; MacMartin, Douglas G.; Kravitz, Ben; Lee, Walker; Simpson, Isla R.; Richter, Jadwiga H. (2020): Reduced Poleward Transport Due to Stratospheric Heating Under Stratospheric Aerosols Geoengineering. In Geophysical Research Letters 47 (17). DOI: 10.1029/2020GL089470.

"We show how the heating results in a feedback where increasing injection rates lead to stronger high‐latitudinal transport barriers. This implies a potential limitation in the high‐latitude aerosol burden and subsequent cooling."

Research Matters: Climate change is driving apple orchards higher up in the Himalayas, and geoengineering could be a stopgap

"A recent study, published in the journal Climatic Change, shows that spraying aerosols of sulphate particles into the atmosphere could block solar radiation and combat global warming. It suggests spraying into the stratosphere—a layer of our atmosphere extending up to 31 miles— to aid the apple cultivation of Himachal Pradesh."
