Traffic Jams & Sea Levels (Part Two)

Traffic Jams & Sea Levels (Part Two)

Host: Lester Graham
Show date: 06/18/2009

Summary:
Traffic jams function like bombs. We take a look at how 'phantom traffic jams' - when everyone slows down for no apparent reason - have a pattern like detonation waves after an explosion. And... sea levels are rising fast... putting some coastal towns at risk. Tamara Keith visited one community that's taking a more natural approach to protecting their shoreline. Tearing down bulkheads... and putting up plants.
