Did a Volcanic Eruption in 1783 Change the Climate in Europe?

by David Shultz 17 May 2019

A new model of the Laki eruption in Iceland suggests that normal climate variability was to blame for the anomalously warm summer.

Volcano in Iceland Is One of the Largest Sources of Volcanic CO2

by Terri Cook 8 November 201811 January 2019

High-precision airborne measurements, in combination with atmospheric modeling, suggest that the Katla subglacial caldera may be one of the planet’s biggest sources of volcanic carbon dioxide.

A Volcanic Trigger for Earth’s First Mass Extinction?

by L. Joel 30 May 201730 May 2017

Abnormally high levels of mercury in Ordovician rocks may imply that a huge surge of volcanism took place at a time when much of the planet’s ocean life vanished.

Scientists use balloons to measure atmospheric ash and assess how volcanic eruption eruptions affect climate.

Volcanic Ash Contributes to Climate Cooling

by A. Branscombe 25 October 201625 October 2016

A new study shows that atmospheric ash reflects solar radiation months after volcanic eruptions.

A thermal infrared image of the 1991 Mount Pinatubo eruption shows cooler temperatures at the top of the ash cloud.

Volcanic Eruptions Stir an Already Complex Atmosphere

by L. Crane 25 July 201629 July 2016

A study of Earth's atmospheric response to major volcanic eruptions seeks to reconcile contradictions between observations and climate models.

Fewer Tropical Cyclones Form After Volcanic Eruptions

by C. Sullivan 24 February 201624 February 2016

Volcanic eruptions aren't all bad—in some cases, they can lower the frequency of tropical cyclones in the North Atlantic by emitting sulfate aerosols.
