The Challenge of Simulating the Warmth of the Mid-Miocene Climatic Optimun in CESM1

The mid-Miocene climatic optimum (MMCO) is an intriguing climatic period due to its above-modern temperatures in mid-to-high latitudes in the presence of closeto-modern CO2 concentrations. We use the recently released Community Earth System Model (CESM1.0) with a slab ocean to simulate this warm period, incorporating recent Miocene CO2 reconstructions of 400 ppm (parts per million). We simulate...

Modeling the Miocene Climatic Optimum. Part I: Land and Atmosphere

This study presents results from the Community Climate System Model 3 (CCSM3) forced with early to middle Miocene (;20–14 Ma) vegetation, topography, bathymetry, and modern CO2. A decrease in the meridional temperature gradient of 6.58C and an increase in global mean temperature of 1.58C are modeled in comparison with a control simulation forced with modern boundary conditions. Seasonal polewar...

Simulation of the Middle Miocene Climate Optimum

[1] Proxy data constraining land and ocean surface paleotemperatures indicate that the Middle Miocene Climate Optimum (MMCO), a global warming event at 15 Ma, had a global annual mean surface temperature of 18.4 C, about 3 C higher than present and equivalent to the warming predicted for the next century. We apply the latest National Center for Atmospheric Research (NCAR) Community Atmosphere M...

Antarctic ice sheet sensitivity to atmospheric CO2 variations in the early to mid-Miocene.

Geological records from the Antarctic margin offer direct evidence of environmental variability at high southern latitudes and provide insight regarding ice sheet sensitivity to past climate change. The early to mid-Miocene (23-14 Mya) is a compelling interval to study as global temperatures and atmospheric CO2 concentrations were similar to those projected for coming centuries. Importantly, th...

The Global Extent of the Mid Stratospheric CN Layer: A Three-Dimensional Modeling Study

For the first time the global extent of a mid stratospheric new particle layer is addressed, using the National Center for Atmospheric Research Community Earth SystemModel, version 1 (CESM1), with the high-top atmosphere component, the Whole Atmosphere Community Climate Model (WACCM). The CESM1(WACCM) version has been configured for pure sulfate formation in the stratosphere, including the form...
