The lecture series at the Carnegie Institution for Science always has interesting stuff.  The latest is Margaret Tolbert from the University of Colorado, speaking on Hazy Skies on Early Earth:  Lessons from Saturn’s Moon Titan.  And I must add that the talks I’ve been to have unabashedly lobbied for carbon trading (which I personally believe is going to produce the mother of all unintended consequences), and it is generally part of the Q&A.  There; fair warning.

Saturn’s moon, Titan, is covered by a thick organic haze that completely shrouds the surface from view. Such a mysterious haze might have also been present on Earth billions of years ago. Comparing the hazes that form in these two distant lands can help us learn more about the climate and habitability of our own planet in ancient times.
