YSM 2009 - Talks

David Anderson

World Data Center for Paleoclimatology, NOAA, USA

David Anderson is the Director of the World Data Center for Paleoclimatology, and an Associate Professor Adjoint at the University of Colorado. His responsibilities include a mix of data management (scientific stewardship and internet data delivery) and research (on Asian monsoons and carbon cycle reconstructions).  The World Data Center is operated by the National Climatic Data Center of the National Oceanic and Atmospheric Administration (NOAA), and exists to provide the data and information scientists need to understand natural climate variability and future climate change.

Alicia Newton

Associate Editor, Nature Geoscience, UK

Alicia Newton is an Associate Editor with Nature Geoscience, a research journal from Nature Publishing launched in January 2008. Her primary responsibilities include handling manuscripts in the fields of paleoclimatology, hydrology, paleontology, and sedimentology. She also works on “News and Views” and “Research Highlights”, and contributes regularly to “Nature Reports Climate Change”. Before working for Nature Geoscience, Alicia’s research focus was on climate and hydrographic variability in the Indo-Pacific Warm Pool over the past 26,000 years. She also studied trace element variability within the tests of foraminifera.

Gavin Schmidt

Goddard Inst. for Space Studies, NASA, USA

Gavin Schmidt is a climate modeler at the NASA Goddard Institute for Space Studies in New York and is interested in modeling past, present and future climate. He works on developing and improving coupled climate models and, in particular, is interested in how their results can be compared to paleoclimatic proxy data. He was cited by Scientific American as one of the 50 Research Leaders of 2004, and has worked on Education and Outreach with the American Museum of Natural History, the College de France, the New York Academy of Sciences and the website RealClimate.org. He was on the “Daily Show” once.
