Abstract

A dust with climate The EPICA ice core, drilled at Dome C in East Antarctica, provides an undisturbed record of the past eight climatic cycles. Dust particles in the atmosphere can affect temperature by absorbing or reflecting solar radiation, and previous work suggested that production, transport and deposition of dust is influenced by climatic changes on glacial-interglacial timescales. A new analysis of the record of dust deposits in the EPICA core shows that the flux in atmospheric dust content increasingly correlates with Antarctic temperature during glacial periods as the climate gets colder, indicative of a progressive coupling of the climates of Antarctica and lower latitudes. An observed 25-fold increase in glacial dust flux over all eight glacial periods may reflect a strengthening of South American dust sources, and longer dust-particle lifetimes in the upper troposphere due to a reduced hydrological cycle during ice ages.
