A Return to New York City

I lived in Manhattan from 1968 until 1973 and from 1993 until 2000.  So, I've seen Manhattan at two different points in time.   Now, I'm just another tourist.   But, in early February 2011 --- I will make my return with My NYU Talk  on February 3rd 2011.    As usual, I will be talking about Green Cities and Climatopolis.
