Research Interests
My research interests have a definite bottom line: to understand
the mechanisms of climate change that have made the ice ages
come and go, and to apply that understanding to prediction of
possible future climate change. Studies include:
(1) climate change by Milankovitch isolation variation,
(2) role of Hudson Strait ice dams in deglaciation,
(3) role of Mediterranean overflow water in initiating new glaciations,
(4) synthesis of events and causes of the last two major deglaciations,
and
(5) historic major variations of climate. These studies have
been stimulated by six seasons of field work on Barbados which
involved surveys of coral terraces formed during the last interglacial,
and collection of coral samples for dating by thermal ionization
mass spectrometry.
