My primary interests are in the realm of modeling and analyzing climate-carbon cycle interactions, with a particular focus on interannual variability and future climate change.
- Understanding the relationships between climate variability and carbon cycle variability
- Characterizing the role of natural carbon cycle variability during the 20th century
- Exploring the sensitivity of the coupled climate-carbon cycle system to different climate change scenarios
Prior Research Topics
- execution of the Earth System Model (ESM) for the Intergovernmental Panel on Climate Change Fifth Assessment Report (IPCC AR5)
- mesoscale modeling of wind energy resources and sea breeze circulations
- regional and hemispheric response of snowfall to increases in greenhouse gas (GHG) concentrations

|Does TCRE depend on the rate of carbon emissions?
In a recent paper published in Geophysical Research Letters, we explore this question using the GFDL’s ESM2G coupled climate-carbon cycle model. Our results indicate that TCRE varies between 0.76 and 1.04 °C/TtC for emissions ranging between 2 GtC/year and 25 GtC/year. TCRE is highest for both the very low and very high emissions rates, but is lowest for emission rates that are close to present-day rates (i.e. 5 to 10 GtC/year). We also demonstrate that the TCRE signal difficult to detect under low emissions and on short timescales. Furthermore, the climate response to zero-emissions depends on prior emission rates. [more]
Our paper was also highlighted in the April 2014 issue of Nature Climate Change.
