Hysteresis in Cenozoic Antarctic ice-sheet variations (2005, methodology): “First, a suite of five GCM climate simulations is performed, with orbital configurations updated every 10,000 years in order to resolve an idealized orbital cycle with 20, 40 and 80 ka periodicities (explained in detail in DeConto and Pollard, 2003a,b).”
Antarctic topography at the Eocene–Oligocene boundary (2012, background): “Ice sheet modeling forced by orbital cycles under a reduced atmospheric CO2 indicate these fluctuations may have been on a similar scale to those of northern hemisphere Pleistocene ice sheets (DeConto and Pollard, 2003; Jamieson and Sugden, 2008) and probably represented Antarctic ice volumes rangin”
Evolution and diversity of the benthic fauna of the Southern Ocean continental shelf (2004, background): “Continental glaciation was probably initiated about 35 Ma BP, and the individual ice-sheets almost certainly fluctuated in size in response to orbital variations on Milankovitch frequencies (Barrett et al. 1987, Fielding et al. 2000, Powell et al. 2000, Naish et al. 2001, DeConto & Pollard 2003).”
Regional climate shifts caused by gradual global cooling in the Pliocene epoch (2004, positive): “A small decrease in carbon dioxide concentration could explain the cooling at the end of the warm period if coupled with positive feedbacks, as suggested for the onset of significant Antarctic glaciatio”
Nonlinearities, Feedbacks and Critical Thresholds within the Earth's Climate System (2004, methodology): “• Develop GCMs coupled to low-dimensional energy balance ice sheet/lithosphere hybrid models (e.g., Deconto and Pollard, 2003) that can simulate the interaction between hydrosphere, atmosphere and land over a wide range of spatial (continental to global) and temporal (centennial, millennia) scales.”
Target atmospheric CO2: Where should humanity aim? (2008, neutral): “In the gla-ciated world (cid:1) T do is limited by the freezing point in the deep ocean.”
Rapid stepwise onset of Antarctic glaciation and deeper calcite compensation in the Pacific Ocean (2005, neutral): “The glaciation was initiated, after climatic preconditionin”
Why is the Land Green and the Ocean Red (2004, background): “In addition, modeling studies show that declining atmospheric CO2 levels played a major role in ice volume increase at the same time (DeConto and Pollard 2003).”
