New research indicates the cooling effect of rare, large eruptions will increase, whereas the effects of more frequent, smaller eruptions will be reduced.
Volcanoes can warm as much as they cool. Prior simulations have neglected the important warming effects of sulfur dioxide emissions, making some results colder than they should be.
In lab experiments and models, researchers uncover how ash can affect the standing shock waves of erupting volcanoes. Their findings may lead to new predictions of volcanic ash hazards.
A new model of the Laki eruption in Iceland suggests that normal climate variability was to blame for the anomalously warm summer.
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.
The frequency of eruptions with a Volcanic Explosivity Index of 7 is only one or two per thousand years but we cannot afford to be complacent.
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.
Volcanic Ash as an Active Agent in the Earth System (VA3): Combining Models and Experiments; Hamburg, Germany, 12–13 September 2016
A new study shows that atmospheric ash reflects solar radiation months after volcanic eruptions.
A study of Earth's atmospheric response to major volcanic eruptions seeks to reconcile contradictions between observations and climate models.
