GISS Wednesday Lunch Seminar Series
Michael Way, 2011-04-27
I would like to lead a discussion of several papers (along the lines of a journal club discussion) from the past year discussing the "Faint Young Sun Paradox".
Caleb Scharf will give a brief introduction to the topic while I will present a couple slides based on the papers below so that we are all on the same footing.
I suggest people read or scan the following to participate in this discussion:
