As noted on another list, there are numerous errors in Gelbspan's article. 
There was no two-foot snowfall in LA this year.  (There was snow up in the
mountains, but that's where it belongs.)  There was no 42-inch snow storm in
Boston in January--rather, that was the total for the entire month.  (Winter
in New England wasn't short, either, but dragged on into April.)

In any event, global warming isn't about specific events; it's about
averages and trends.

More to the point, experienced meteorologists see little connection between
global warming and Katrina in particular, or hurricanes in general.  The
September issue of Discover magazine has an interview with Dr. William Gray,
in which he explains the cyclical nature of storm patterns:

(A similar interview recently appeared in the NY Times.)

Other posters have discussed how important it is for science centers to
teach about global warming, and have offered advice on how to do so.  But,
as with all topics we cover, that education needs to be based on reliable facts.
