This is the estimate for the Gulf of Mexico oil spill in less than a year, according to simulations by US scientists:
The simulation is based on 5 typical years' climate and does not include any estimate of biological degradation or other accumulation processes such as the formation of tar balls. Whatever the case it is a most worrisome forecast for SE USA, parts of Mexico and even possibly Europe, where the Gulf Stream eventually ends.
The catastrophe, still mostly uncontrolled, has began to be dubbed "the American Chernobyl".
