The AGU lectures for teachers are some of the most informative I have ever
attended.
The one on how the meteorite that coincided with the disappearance of the
dinosaurs hit on a sulfate rich deposit and excavated a 100 ile wide hole
filling the stratosphere with sulfuric acid was particularly full of useful
information.
