When: Wednesdays 14:00-15:00 (usually - special times marked in schedule)
Where: GFI Ø 321 (usually - special locations marked in schedule)
Who: All are welcome.

Aims: Improve critical reading skills, develop methods to evaluate research papers, remain current with the literature, broaden background knowledge on climate issues.

Presenters are asked to prepare a 5-minute introduction of the paper and and lead the discussion. In addition, it is useful to have all the graphics from the paper ready on slides.

The introduction should present the general context of the study and the main result. The goal is to establish the relevant background for the study: ensure that everyone is in the same forest, but avoid the common mistake of singling out particular trees. This is often best accomplished using a few simple graphics that are not from the paper, and a key result figure from the paper. For the discussion, come prepared with a list of questions to get at standard "reviewer" issues such as: What gap in scientific knowledge does the paper fill? Is the methodology appropriate for addressing the scientific questions raised? Do the conclusions follow from the evidence? Are biases, limitations, assumptions, uncertainties and alternative explanations adequately documented and discussed?

Feel free to volunteer, and also to choose papers that are outside your area of focus or research expertise.
