Atmospheric circulation and hydroclimate impacts of alternative warming scenarios for the Eocene

Henrik Carlson and Rodrigo Caballero

Data sets

Community Atmospheric Model 3.1 CESM

Short summary
Climate models are able to simulate the surface temperature of the early Eocene as reconstructed from paleoclimatology data, but only by using extremely high CO2 concentrations or clouds that are more transparent to solar radiation. We explore the potential for distinguishing among these two forcing agents via their impact on regional climate. Better constraining the radiative forcing that led to Eocene warmth has important implications for understanding Earth's climate sensitivity.
