Scale of disaster becoming apparent as tar balls reach Florida and Gulf of Mexico no-fishing zone doubles in sizehttp://www.guardian.co.uk/environment/2010/may/18/oil-spill-threatens-atlantic-coastThere was mounting evidence tonight that the scale of the oil spill disaster in the Gulf of Mexico has grown beyond all the initial worst-case scenarios, as thousands of gallons of oil continued to gush from the sea floor.
In Key West, coastguard officials said about three tar balls an hour were washing up on the beaches at a state park at the southernmost point of the Florida Keys.
Such evidence suggests the damage wreaked by the spill – which began with an explosion on BP's Deepwater Horizon rig on 20 April – could now grow larger, with crude oil caught up in the powerful loop current that travels a much wider course through the Gulf and up the Atlantic coast. In response to the tar sightings, Washington doubled the no-fishing zone to 19% of the waters in the Gulf.
The Obama administration admitted today it had underestimated the risks of offshore drilling. In a highly charged hearing in the Senate, Ken Salazar, the interior secretary, conceded failures in oversight by the agency responsible for policing offshore drilling. "We need to clean up that house," he told the energy and natural resources committee.
