The overall direction of this research is toward increased understanding of interactive processes in the Earth's physical environment and the development of a more coherent picture of its sensitivities to natural and anthropogenic change. The carbon dioxide greenhouse effect is a continuing source of research problems, and one of the most pressing problems is how to determine the onset of a theoretically predicted warming. Both of these topics receive considerable attention from CIRES researchers.
Jocelyn Turnbull
My research expertise is in the atmospheric carbon cycle, primarily using radiocarbon and other tracers to understand the source and fate of fossil fuel CO2 emissions at scales from individual point sources to urban areas, regions and globally. I hold joint appointments at CIRES and at GNS Science, New Zealand, and co-chair the WMO Integrated Global Greenhouse Gas Information System (IG3IS) program.

Christopher Amante
I'm a Geospatial Research Scientist at the NOAA National Centers for Environmental Information (NCEI) through the Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado Boulder. I develop integrated bathymetric-topographic digital elevation models (DEMs) to support coastal inundation modeling. My research interests include quantifying the uncertainty in coastal DEMs, and incorporating that uncertainty and uncertainty in sea-level rise projections and storm surge models in probabilistic, future flood risk assessments.
