Medieval Irish chronicles reveal persistent volcanic forcing of severe winter cold events, 431–1649 CE – Mayewski et. al. – Environ. Res. Lett., 2013

Abstract Explosive volcanism resulting in stratospheric injection of sulfate aerosol is a major driver of regional to global climatic variability on interannual and longer timescales. However, much of our knowledge of the climatic impact of volcanism derives from the limited number of eruptions that have occurred in the modern period during which meteorological instrumental records […]

Variations in snow and firn chemistry along US ITASE traverses and the effect of surface glazing. The Cryosphere, 7, 2, 515-535. doi:10.5194/tc-7-515-2013. – Dixon/Mayewski et al.

This study provides a baseline from which changes in the chemistry of the atmosphere over Antarctica can be monitored under expected warming scenarios and continued intensification of industrial activities in the Southern Hemisphere. It is the first study to measure more than 25 chemical constituents in the surface snow and firn across extensive regions of […]

West Antarctica’s Sensitivity to Natural and Human-forced Climate Change Over the Holocene – Mayewski et al. 2012

Climate reconstructions developed from a West Antarctic deep ice core (Siple Dome) combined with Antarctic ice sheet reconstructions show that recent poleward migration of the Southern Hemisphere westerlies, coincident with greenhouse gas rise and the Antarctic ozone hop, has led to unprecedented penetration of air masses bringing warmth, extra-Antarctic source dust, and anthropogenic pollutants into […]
