The first was on Sandy and climate change, with two Columbia researchers. This is available as a podcast at http://www.wnyc.org/shows/bl/2012/nov/15/climate-science-and-sandy/.
Also of note from this segment was the link to a Columbia climate forum called After Sandy: Climate and Our Coastal Future. That is happening on Monday (11/19), and you have to register (but you can also stream this, from what I understand): http://www.worldleaders.columbia.edu/events/after-sandy-climate-and-our-coastal-future.
In a few minutes, Catherine Seavitt (from our 10/24 discussion), and Eric Sanderson (a recent GEOS speaker and author of "Manahatta") will be on the Leonard Lopate show discussing the future of NYC's waterfront in the wake of Sandy.
