Rm. 439 Telephone: 683-4930 e-mail: dburdige "at" odu "dot" edu Office Hours: Monday 9-10 AM; Thursday 1-2 PM; or by appointment This is primarily a core course for undergraduate ocean and earth science majors, although other undergraduates with a science background should be prepared for this class. I hope that the students in the class will take an active role in the class. As such I ask that you be diligent in keeping up with all required readings, so that we can have thoughtful, educated discussions during class. In this class we will examine the development of the earth as a habitable planet, and look at processes that link the Earth's atmosphere, hydrosphere (oceans), geosphere and biosphere. In the course of this discussion we will also define the scientific basis for understanding the magnitude and temporal scales of recent global environmental changes. 12/14/07 - I have completed the grading and things should be up in Blackboard and Leo Online soon.  Click here to see how I calculated the final grades. 12/10/07 -  HW 9 has been graded.  Come by my office to pick up your copy if you'd like.  The answers to this homework can be downloaded here. 9/28/07 - Check out the following article on the NSF web site about new evidence regarding the timing of oxygen accumulation in the atmosphere. Global environmental change on two very different time scales - natural versus anthropogenic change?

This data set clearly shows that there is some linkage between CO2 and global climate, although the nature of their relationship is still not well understood. Reconstruction of Northern Hemisphere temperature anomaly trend from 1000 A.D. to present from dendroclimatic, coral, and ice-core proxy records as calibrated by instrumental measurements. The thin curves give reconstruction and raw data from 1000-1998 A.D. A smoothed version (thick solid), linear trend from 1000 to 1850 A.D. (long dashed), and two standard error limits (yellow shaded) are also shown. Note the recent rapid increase in temperatures over the past 50-100 yrs that appears to be out of line with the general trends of the last thousand years.
