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.
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.
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.
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.
