Abstract

We review the available reconstructions of the Indian summer and winter monsoons using well-dated natural climatic archives such as tree-rings, corals, ice-cores, speleothems and ocean sediments. Oxygen isotopic analyses of cellulose from annual growth rings of teak trees on an intra-annual scale hold high promise for reconstructing rainfall during both monsoons. Oxygen isotopic variations in corals and ice-cores seem to respond to atmospheric and ocean processes and may not yield direct reconstructions of monsoonal precipitation. Oxygen isotopic variations in speleothem and multiple proxies from ocean sediments consistently show that monsoon precipitation increased during the Holocene. The connection between insolation changes and monsoon needs to be carefully reassessed.
