Gulf Oil Spill Is Bad, but How Bad?

Gulf Oil Spill Is Bad, but How Bad? The oil spill in the Gulf of Mexico is bad — no one would dispute it. But just how bad?

Some experts have been quick to predict apocalypse, painting grim pictures of 1,000 miles of irreplaceable wetlands and beaches at risk, fisheries damaged for seasons, fragile species wiped out and a region and an industry economically crippled for years.

President Obama has called the spill “a potentially unprecedented environmental disaster.” And some scientists have suggested that the oil might hitch a ride on the loop current in the gulf, bringing havoc to the Atlantic Coast.

Yet the Deepwater Horizon blowout is not unprecedented, nor is it yet among the worst oil accidents in history. And its ultimate impact will depend on a long list of interlinked variables, including the weather, ocean currents, the properties of the oil involved and the success or failure of the frantic efforts to stanch the flow and remediate its effects.

As one expert put it, this is the first inning of a nine-inning game. No one knows the final score.

The ruptured well, currently pouring an estimated 210,000 gallons of oil a day into the gulf, could flow for years and still not begin to approach the 36 billion gallons of oil spilled by retreating Iraqi forces when they left Kuwait in 1991. It is not yet close to the magnitude of the Ixtoc I blowout in the Bay of Campeche in Mexico in 1979, which spilled an estimated 140 million gallons of crude before the gusher could be stopped.

And it will have to get much worse before it approaches the impact of the Exxon Valdez accident of 1989, which contaminated 1,300 miles of largely untouched shoreline and killed tens of thousands of seabirds, otters and seals along with 250 eagles and 22 killer whales.

No one, not even the oil industry’s most fervent apologists, is making light of this accident. The contaminated area of the gulf continues to spread, and oil has been found in some of the fragile marshes at the tip of Louisiana. The beaches and coral reefs of the Florida Keys could be hit ATM Partsif the slick is captured by the gulf’s clockwise loop current.
