Hurricane Alex has made Gulf coast beaches particularly vulnerable. "With this weather, we lost all the progress we made," says scientist.
Hurricane season is upon us and that could mean trouble for the 31,000 miles of Gulf oil pipelines that snake across the floor of the Gulf.
The plan to build 90 miles of sand berms to protect Louisiana wetlands from the Gulf oil spill is now getting under way. But it could take nine months and have unintended consequences.

Despite BP's efforts, only a small percentage of the oil from the Gulf of Mexico oil spill will be cleaned up, say experts.
