Session ID#: 13714

Session Description:
Aerosol and cloud radiative forcings are responsible for the large uncertainty in the overall radiative forcing over the industrial period and limit our ability to constrain climate sensitivity, but their role in paleoclimates has received limited recognition. Natural aerosols such as dust, sea-salt, ash, soot and emissions from vegetation have undoubtedly varied in Earth history, impacting radiative processes in the atmosphere, cloud formation (direct and indirect effects) and hydrological processes.

We welcome data and model contributions that consider changes in the magnitude and variability of natural aerosols and or cloud processes at all timescales (millennial to long-term). We aim to facilitate discussions between the modeling and data communities in how best to move forward in constraining pre-industrial ‘pristine’ climate sensitivity to aerosols and clouds, as well as move beyond CO2  forcing and temperature comparisons in improving our understanding of proxy reconstructions and model-data comparisons.
