Forecasting the climate response to volcanic eruptions: prediction skill related to stratospheric aerosol forcing

open access: yesEnvironmental Research Letters, 2018
The last major volcanic eruptions, the Agung in 1963, El Chichon in 1982 and Pinatubo in 1991, were each associated with a cooling of the troposphere that has been observed over large continental areas and over the Western Pacific, the Indian Ocean and ...

Volcanic forcing of the Lomagundi–Jatuli carbon isotope excursion [PDF]

open access: yesProceedings of the National Academy of Sciences
The Lomagundi–Jatuli Event (LJE), Earth’s most pronounced and prolonged positive carbon isotope excursion, followed the Great Oxidation Event and remains enigmatic in origin. We present a Pb–Pb isochron age of 2,194 ± 5 Ma for black shales from the Francevillian FB Formation, Gabon—an LJE type locality—coinciding with the ...

Four-dimensional distribution of the 2010 Eyjafjallajökull volcanic cloud over Europe observed by EARLINET [PDF]

open access: yes, 2012
The eruption of the Icelandic volcano Eyjafjallajökull in April–May 2010 represents a "natural experiment" to study the impact of volcanic emissions on a continental scale.

Relative Roles of Land and Ocean Cooling in Triggering an El Niño Following Tropical Volcanic Eruptions

open access: yesGeophysical Research Letters, 2022
Paleoclimate evidence suggests that tropical volcanic eruptions could increase the likelihood of El Niño occurrence. Previous numerical model studies with zonally uniform volcanic aerosol forcing suggested the roles of land cooling‐induced monsoon ...

Robust global ocean cooling trend for the pre-industrial Common Era [PDF]

open access: yes, 2015
The oceans mediate the response of global climate to natural and anthropogenic forcings. Yet for the past 2,000 years — a key interval for understanding the present and future climate response to these forcings — global sea surface temperature changes ...

Climate variability of the mid- and high-latitudes of the Southern Hemisphere in ensemble simulations from 1500 to 2000 AD [PDF]

open access: yesClimate of the Past, 2012
To increase the sparse knowledge of long-term Southern Hemisphere (SH) climate variability, we assess an ensemble of 4 transient simulations over the last 500 yr performed with a state-of-the-art atmosphere ocean general circulation model.

Revising midlatitude summer temperatures back to A.D. 600 based on a wood density network [PDF]

open access: yes, 2015
Annually resolved and millennium-long reconstructions of large-scale temperature variability are primarily composed of tree ring width (TRW) chronologies.

Volcanic impact on terrestrial and aquatic ecosystems in the Eastern Mediterranean

open access: yesCommunications Earth & Environment, 2023
Natural disturbances such as volcanic eruptions provide a unique opportunity to study past ecological dynamics. Here we illustrate the response of terrestrial and aquatic ecosystems to volcanic eruptions in connection to prevailing climate conditions. We

Neglecting future sporadic volcanic eruptions underestimates climate uncertainty

open access: yesCommunications Earth & Environment
Most climate projections represent volcanic eruptions as a prescribed constant forcing based on a historical average, which prevents a full quantification of uncertainties in climate projections.

Assessing the climate impact of an improved volcanic sulfate aerosol representation in E3SM [PDF]

open access: yesGeoscientific Model Development
Accurately simulating historical surface temperature variations is essential for evaluating climate models, yet many struggle to reproduce the mid-20th-century temperature trends associated with significant volcanic eruptions.
