According to peer-reviewed work (O My God! Peer Review!), there is so a big plume of oil in the Gulf: far below the surface, colourless and odourless. The peer-reviewed folks say it will be around for months, so two different commentators have no hesitation in saying it will be years.
Repeated suggestions that the U.S. government has been "wrong" in its reassurances, but quietly it seems to emerge that the coastline, including many fish and the jobs of many people, have indeed been saved. That's what governments are supposed to do.
Still no mention of the fact that there is oil at the bottom of the Gulf all the time, and some of the wildlife would die without it.
