While it took Japan over two years to admit the Fukushima situation on the ground is “out of control“, a development many had predicted for years, a just as important topic is what are the implications of this uncontrolled radioactive disaster on not only the local environment and society but also globally, particularly Japan’s neighbor across the Pacific – the US.
To be sure, there has been much speculation, much of it unjustified, in the past two years debating when, how substantial and how acute any potential debris from Fukushima would be on the US. Which is why it was somewhat surprising to see the NOAA come out with its own modeling effort, which shows that not only “some buoyant items first reached the Pacific Northwest coast during winter 2011-2012” but to openly confirm that a debris field weighing over 1 million tons, and larger than Texas is now on the verge of hitting the American coastline, just west off the state of California.
Obviously, the NOAA in releasing such a stunner could well be hammered by the administration for “inciting panic” which is why it caveated its disclosure carefully:
Many variables affect where the debris will go and when. Items will sink, disperse, and break up along the way, and winds and ocean currents constantly change, making it very difficult to predict an exact date and location for the debris’ arrival on our shores.
The model gives NOAA an understanding of where debris from the tsunami may be located today, because it incorporates how winds and ocean currents since the event may have moved items through the Pacific Ocean. This model is a snapshot of where debris may be now, but it does not predict when debris will reach U.S. shores in the future. It’s a “hindcast,” rather than a “forecast.” The model also takes into account the fact that winds can move different types of debris at different speeds. For example, wind may push an upright boat (large portion above water) faster than a piece of lumber (floating mostly at and below the surface).
