Non-erupting volcanoes leak a surprisingly high amount of sulfur-containing gases. A Greenland ice core shows that volcanoes quietly release at least three times as much sulfur into the Arctic atmosphere than estimated by current climate models. Aerosols are the most uncertain aspect of current climate models, so better estimates could improve the accuracy of long-term projections.
