There’s one word for this meeting: packed.

I’ve been coming to AGU for more than a decade, and there are more people here than ever. There are more than 13,500 abstracts and 1,100 oral sessions. The numbers of presentations, and attendees, keep going up. Today, the registration line snaked around the lobby of the Moscone Center in San Francisco and back on itself. Several times.

I sure hope not everybody shows up on Thursday noon to hear Al Gore speak – we’ll never all get in.
