Dwindling Relevance of Large Volcanic Eruptions for Global Glacier Changes in the Anthropocene

Geophysical Research Letters, Volume 48, Issue 14, 28 July 2021., 2021
Abstract Large volcanic eruptions impact climate through the injection of ash and sulfur‐containing gases into the atmosphere. While the ash particles fall out rapidly, the gases are converted to sulfate aerosols that reflect solar radiation in the stratosphere and cause a lowering of the global mean surface temperature.

How Does a Pinatubo‐Size Volcanic Cloud Reach the Middle Stratosphere?

Journal of Geophysical Research: Atmospheres, Volume 126, Issue 10, 27 May 2021., 2021
Abstract Volcanic explosions are the most critical replenishing mechanism of the stratospheric aerosol Junge layer. A fresh volcanic cloud comprises mostly sulfur‐bearing gases, volcanic ash, and water vapor. It is commonly assumed that only sulfate aerosols remain in an aged volcanic cloud.

Global Temperature Responses to Large Tropical Volcanic Eruptions in Paleo Data Assimilation Products and Climate Model Simulations Over the Last Millennium

Paleoceanography and Paleoclimatology, Volume 36, Issue 4, April 2021., 2021
Abstract Large volcanic eruptions are one of the dominant perturbations to global and regional atmospheric temperatures on timescales of years to decades. Discrepancies remain, however, in the estimated magnitude and persistence of the surface temperature cooling caused by volcanic eruptions, as characterized by paleoclimatic proxies and climate models.

On the likelihood of future eruptions in the Chilean Southern Volcanic Zone: interpreting the past century's eruption record based on statistical analyses [PDF]

, 2012
A sequence of 150 explosive eruptions recorded during the past century at the Chilean Southern Volcanic Zone (SVZ) is subjected to statistical time series analysis. The exponential, Weibull, and log-logistic distribution functions are fit to the eruption
