Dear colleagues,

With the deadline fast approaching for the AGU Fall Meeting abstract submission (August 1st, 2018), please consider submitting an abstract to session PP030 titled, “Paleo-CO2 recontruction in the Phanerozoic, which will be held in Washington D.C. December 10-14, 2018. This session welcomes contributions examining the history of CO2 variations in the geological past.

The abstract could be submitted here:

Session Description:
The history of atmospheric CO2 variations in the geological past is important to evaluate the role that greenhouse gases played during past climate changes, which also provides a basis for future climate projections. A wide range of paleo-CO2 proxies from marine and terrestrial sedimentary archives have been developed and applied across various timescales. Sources of uncertainty associated with these proxies may be attributed to: 1) uncertainties in empirical calibration; 2) uncertainties in regression model input variables; 3) uncertainties in measurement; 4) uncertainties in age. The conversion of modern calibration to paleo-application is also complicated by a lack of mechanistic understanding of some of these paleo-CO2 proxies. This session aims to bring together researchers that use paleo-CO2 proxies to understand the CO2-climate relationship, with particular focus on clarifying sources of uncertainty inherent to specific proxies. We encourage contributions focused on the development, validation, or application of CO2 proxies in paleoclimate research.
