Course description: This course will entail a weekly seminar-style critical reading of journal articles in paleoclimate (one paper per week, curated by the instructor). This year, we will focus on the causes of past Greenhouse climates (including 'relative' Greenhouse warmth like the Holocene), and feedbacks within those climate states.
Expectations and grading: During the semester, each student will be required to lead the discussion of two papers. Each presenter will be selected one week ahead of time. Papers may be presented informally and with or without visual aids, according to the presenter's preference. The presenter should touch on the paper's main Problem, Claim, Evidence, and Uncertainties. Presenters should encourage discussion by asking questions of the group. Each week, everyone is responsible for reading the paper and participating in the discussions. Readers should also identify and share one part of the paper that they had trouble understanding. Grades will be based on overall participation (50%) and on the effort put into the presentations and discussion-leading (50%).
Meets: Wednesdays 12:20-1:10 pm, BESC 1B81

List of possible papers that look interesting (a work in progress). Sorted in rough stratigraphic order according to the time period considered. This lists reflects the bias of Tom's interests, and not all may be appropriate for this year's topic. Students are very welcome to make their own suggestions!
