11:45am "Global Cycles in the Earth System" - Food: pizza
Location: Donahue Conference Room, Space Research Building
Prof. Richard Peltier (University of Toronto) with
"A Carbon Dioxide "Attractor" in the Neoproterozoic - "Snowball Earth" prevention by DOC re-mineralization" -- pls see the attached flyer.
Abstract
The "snowball Earth" hypothesis posits the occurrence of a sequence of glaciations in the Earth's history sufficiently deep that photosynthetic activity was essentially arrested. Because the time interval during which these events are believed to have occurred immediately preceded the Cambrian explosion of life, the issue as to whether such snowball states actually developed has important implications for our understanding of evolutionary biology.
A model is described that couples the physical climate system to a model of the Neoproterozoic carbon cycle. The model is employed to suggest that the drawdown of atmospheric oxygen into the ocean, as surface temperatures decline, operates so as to increase the rate of mineralization of a massive pool of dissolved organic carbon. This leads directly to an increase of atmospheric carbon dioxide, enhanced greenhouse warming of the surface of the Earth, and the prevention of a hard snowball state.

3:00pm Impact of solar variability and anthropogenic forcing on the whole atmosphere - Food: refreshments
Location: Auditorium, Room #2246 Space Research Bld
Dr. Brasseur was educated at the Free University of Brussels, Belgium with two engineering degrees: one in physics and one in telecommunications and electronics.
The dynamical, chemical and radiative interactions between the different layers of the atmosphere are complex and not well understood. Dynamical perturbations produced at the surface or in the lower atmosphere propagate to the mesosphere and thermosphere, and affect considerably the state of these layers. At the same time, the effects of solar variability propagate into the atmosphere and could have an impact even in the troposphere.

5:00pm CoE Outreach Partnership Wants YOU!! - Food: a delicious dinner
Location: IOE 1680
The number of historically underrepresented minorities in the STEM fields is dismally low. The College of Engineering (CoE) has taken a new approach to address this issue by partnering with the Ypsilanti Public School District (YPSD) to increase the pipeline and open pathways to STEM options for YPSD students. The partnership has received tremendous support by the University and the College and has enjoyed immense publicity through several presentations made to Michigan’s leaders. The program commenced in Fall 2007 and we are looking for YOU to get involved in Winter 2008 and furthermore into the future as this partnership matures!
We are looking for graduate students in engineering and science who want to partner with YPSD teachers by acting as teaching assistants in a structured, joint program.
As a TA, you will develop mentoring relationships with the students and contribute time, knowledge, and energy to the classroom to increase student understanding, appreciation, and interest in science, technology, engineering, and mathematics (STEM). In return, you’ll get valuable teaching experience and learn pedagogy from master teachers. Through the CoE and additional grants, there will be financial support available to volunteers for their efforts.
We will begin promptly at 5pm, Please RSVP by email to Joy Oguntebi at ogunjoy@umich.edu

"In 39 years, I have never written these words in a movie review, but here they are: You owe it to yourself to see this film. If you do not, and you have grandchildren, you should explain to them why you decided not to." - Roger Ebert, Chicago Sun-Times
