Sorry to be so quiet - this was the first week of classes, so I've been distracted.
I'm giving a seminar on Network Theory, as described here:
* [Network theory news](http://johncarlosbaez.wordpress.com/2014/09/28/network-theory-news/).
and I'll try to write course notes as blog articles, starting here:
* [Network theory (part 30)](http://johncarlosbaez.wordpress.com/2014/10/03/network-theory-part-30/).
I also hope to make videos of the seminar, perhaps in the form of "Hangouts on Air". This is one of the things that has been distracting me.
However, now that these things are underway, and the book with Jacob is close to done, I plan to return to the climate network business and start working very hard on that.
