This is a concise list of the talks presented under the Talk tab.  It minimizes scrolling down to find the talk you want to see – if you already know something about the subject.  We may be gradually reworking some of the older talks to make them more self-contained and with more content – to reach a broader audience than was originally intended.

Some meteorological and environmental talks, of a somewhat more technical nature, can be seen here.
