Kroll, Clarissa Alicia; et al. (2020): The Impact of Volcanic Eruptions of Different Magnitude on Stratospheric Water Vapour in the Tropics

Kroll, Clarissa Alicia; Dacie, Sally; Azoulay, Alon; Schmidt, Hauke; Timmreck, Claudia (2020): The Impact of Volcanic Eruptions of Different Magnitude on Stratospheric Water Vapour in the Tropics. In Atmospheric Chemistry and Physics. DOI: 10.5194/acp-2020-1191.

"We analyze tropical volcanic eruptions of different eruption strengths with sulfur (S) injections ranging from 2.5 Tg S up to 40 Tg S using EVAens, the 100-member ensemble of the Max Planck Institute – Earth System Model in its low resolution configuration (MPI-ESM-LR) with artificial volcanic forcing generated by the Easy Volcanic Aerosol (EVA) tool."

Banerjee, Antara; et al. (2020): Robust winter warming over Eurasia under stratospheric sulfate geoengineering – the role of stratospheric dynamics

Banerjee, Antara; Butler, Amy H.; Polvani, Lorenzo M.; Robock, Alan; Simpson, Isla R.; Sun, Lantao (2020): Robust winter warming over Eurasia under stratospheric sulfate geoengineering – the role of stratospheric dynamics. In Atmos. Chem. Phys. Discuss. (in review). DOI: 10.5194/acp-2020-965.

"It has been suggested that increased stratospheric sulfate aerosol loadings following large, low latitude volcanic eruptions can lead to wintertime warming over Eurasia through dynamical stratosphere-troposphere coupling. We here investigate the proposed connection in the context of hypothetical future stratospheric sulfate geoengineering in the Geoengineering Large Ensemble simulations."

Phys.org: The testimony of trees: How volcanic eruptions shaped 2000 years of world history

"Researchers have shown that over the past two thousand years, volcanoes have played a larger role in natural temperature variability than previously thought, and their climatic effects may have contributed to past societal and economic change."

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."

Liu, Fei; et al. 2020: “Could the Recent Taal Volcano Eruption Trigger an El Niño and Lead to Eurasian Warming?”

Liu, Fei, Chen Xing, Jinbao Li, Bin Wang, Jing Chai, Chaochao Gao, Gang Huang, Jian Liu, and Deliang Chen. 2020: “Could the Recent Taal Volcano Eruption Trigger an El Niño and Lead to Eurasian Warming?” Advances in Atmospheric Sciences. https://doi.org/10.1007/s00376-020-2041-z. (in press)

"The Taal Volcano in Luzon is one of the most active and dangerous volcanoes of the Philippines. A recent eruption occurred on 12 January 2020 (Fig. 1a), and this volcano is still active with the occurrence of volcanic earthquakes. The eruption has become a deep concern worldwide, not only for its damage on local society, but also for potential hazardous consequences on the Earth’s climate and environment."

Philippine Daily Inquirer: Global warming and volcanic activity

"The recent spate of volcanic eruptions around the world has people asking if this is connected to the warming of the Earth’s atmosphere. The eruption of Taal Volcano brings this issue closer to home."

Pinke, Z.; et al. (2019): Volcanic mega-eruptions may trigger major cholera outbreaks

Pinke, Z.; Pow, S.; Kern, Z. (2019): Volcanic mega-eruptions may trigger major cholera outbreaks. In Clim. Res. 79 (2), pp. 151–162. DOI: 10.3354/cr01587.

"Reviewing the results of environmental epidemiology, post-volcanic climatology, and environmental history, we focused exclusively on volcanic eruption-ENSO and ENSO-cholera connections in order to establish a hypothesis that large tropical and Northern Hemisphere volcanic eruptions trigger an environmentally driven cascade process via post-volcanic ENSO anomalies. This cascade process has tended historically to lead to cholera outbreaks in Bengal (i.e. the Ganges-Brahmaputra delta region of modern India and Bangladesh)."

Pacific Standard: The Billionaires' Guide to Hacking the Planet

"SRM refers to "solar radiation management," the most frequently discussed form of geoengineering, which involves injecting aerosols in the stratosphere to cool the planet—much like major volcanic eruptions do naturally. The other key term here is "unilateral action." This refers to the possibility that someone might simply take matters into his own hands."

Futurenow: How artificially brightened clouds could stop climate change

"In truth, we already know the action needed to reduce man-made climate change: a rapid reduction in greenhouse gas emissions, replacing fossil fuels with renewable energy. According to the recent Intergovernmental Panel for Climate Change (IPCC) report, the world has just 12 years in which to cut emissions by half, and 32 years (by 2050) to get net emissions down to zero."

Eos: Managing Uncertainties in Climate Engineering

"Climate engineering, or geoengineering, looks at ways to temporarily offset climate change by deliberately modifying the climate system. One of the most studied ideas, which is the focus of a new special issue in the Journal of Geophysical Research: Atmospheres, involves stratospheric sulfate aerosols, mimicking the cooling experienced after large volcanic eruptions [Kravitz et al., 2018]."
