Reassessment of Crete (Greenland) ice core acidity/volcanism link to climate change

Previous comparisons of the Crête (Greenland) ice core acidity record with climate variations of the last 1400 years suggested that changes in volcanism may have significantly influenced climate on this time scale. However, the ice core acidity record consists of volcanically‐induced spikes superimposed on a background acidity of nonvolcanic origin that varied significantly in amplitude. Herein we produce a record of Crête volcanism based solely...
