The PaleoDynamics Lab at the Lamont-Doherty Earth Observatory is led by Prof. Jason E. Smerdon, with strong connections to colleagues in the Division of Ocean and Climate Physics, the Lamont Tree-Ring Laboratory and the NASA Goddard Institute for Space Studies. The broad objective of our group is to characterize and understand climate variability and change on multi-decadal to centennial timescales. Climate research is limited in its ability to understand these climatic variations directly from the instrumental record because such observations are not widely available for more than about 100-150 years. To circumvent this limitation, modern instrumental records are supplemented with climatic proxy records and climate model simulations to help characterize these low-frequency modes of change. Our group uses numerical models, climate proxy records and statistical methods to better understand the variability of climate over decades to centuries. We are particularly interested in how multiple climate proxies can be combined to yield hemispheric and global maps of climate variability spanning the Common Era (the last two thousand years), how climate models represent climatic change over this time period, and how to use model-data comparisons on paleoclimatic timescales to inform future climate projections. Several of our recent efforts are highlighted below and all of our publications are publicly available at our Publications page.
