An Introduction to Earth's Glacial Cycles, Richard McGehee, School of Mathematics |
|
|
For the last million years, Earth's climate has alternated between periods where vast ice sheets cover much of the northern continents and periods of relative warmth, such as we have been experiencing for the last 8000 years. The theory that changes in Earth's orbital parameters are driving these cycles will be explored in this lecture. |

Recent Developments in the Theory of Glacial Cycles, Richard McGehee, School of Mathematics |
|
|
The 21st Century has produced a variety of advances toward resolving the discrepancies between the climate record and the predictions of the Milankovitch theory. |

Underwater Mathematics: Illuminating Deep-Reaching Ocean Eddies in Climate Models, Samantha Oestreicher, School of Mathematics |
|
|
Understanding ocean circulation is vital to developing accurate predictive models for global climate change. Los Alamos National
Laboratory's (LANL's) Climate, Ocean and Sea Ice Modeling project (COSIM) specializes in very high resolution computer modeling. The
model output from these runs provides valuable data in areas we can't normally observe like under Arctic ice sheets or in deep waters.
Our aim is to characterize eddies in the more challenging realm of the Arctic, where very little is known. Several eddy identification
markers will be discussed as well as the results of those markers on COSIM's Parallel Ocean Program (POP). Warning: This talk contains
accessible mathematics and some awesome images! |

An Introduction to Energy Balance Models, Richard McGehee, School of Mathematics |
|
|
Simple models of the balance between the energy from the sun and the energy reradiated into space can explain some global features of the Earth's climate. |

Huyber's Glacial Cycles Model, Richard McGehee, School of Mathematics |
|
|
The long period late Pleistocene glacial cycles can be viewed as driven by obliquity under the assumption that certain obliquity changes do not trigger deglaciations. Huyber's paper is available online. |
