An Introduction to Glacial Cycles, Richard McGehee, School of Mathematics |
|
|
The Earth has been experiencing cycles of advancing and retreating ice sheets for millions of years. The theory that these cycles are driven by changes in the Earth's orbital parameters will be explored. |

Recent Developments in the Theory of Glacial Cycles, Richard McGehee, School of Mathematics |
|
|
Paleoclimate data gathered in the last thirty years has challenged previous theories and has given rise to a variety of models. |

Studying fast/slow dynamics of Shallow-Water Equations and its
use for heterogeneous computing, Samantha Oestreicher, School of Mathematics |
|
|
We will be considering the use of ocean dynamic equations
in global climate models and the possible algorithm developments which
may decrease computation time. In particular, we will investigate how
the shallow water equations can be decoupled into fast and slow
dynamics. |

Terrestrial Carbon Sinks,
Samantha Oestreicher, School of Mathematics |
|
|
I will be introducing the carbon sequestration tactics of
peatlands and the possible long term terrestrial carbon sequestration
that they provide. A conceptual model for how this type terrestrial
carbon storage could force the glacial cycles and provide some
explanation for the dynamics of glacial cycles. |

On the Jormungand global climate state,
James Walsh, Oberlin College, visiting the School of Mathematics |
|
|
We report on recent work of Abbot, Voigt and Koll in which an
argument is made for the existence of a stable global climate state in
which very nearly all of the Earth is ice-covered. This "Jormungand" state
presents a potential model for Neoproterozoic glaciations.

An Introduction to Energy Balance Models,
Richard McGehee, School of Mathematics |
|
|
The sun provides the energy driving the Earth's weather and climate. The incoming radiation from the Sun is balanced by the outgoing long wave radiation escaping into space. Even a slight inbalance in these energy fluxes can cause climate change. Simple models of this energy inbalance will be introduced. |
