Extratropical volcanic eruptions

vics nat geo jan 19VICS working group members Matthew Toohey et al. published a paper in Nature Geoscience earlier this week on extratropical volcanic eruptions.

In "Disproportionately strong climate forcing from extratropical explosive volcanic eruptions", the authors use ice-core-derived volcanic stratospheric sulfur injections and Northern Hemisphere summer temperature reconstructions from tree rings to show that, in proportion to their estimated stratospheric sulfur injection, extratropical explosive eruptions since 750 CE have produced stronger hemispheric cooling than tropical eruptions.
