  Decreasing iron?

  I don't know if Mr. George is going to read or respond to these comments, but if so I would like to know what evidence he has that the supply of iron to the ocean in the form of dust is declining.  Certainly iron fertilization only works in high nutrient regions of the ocean where plankton activity is limited by an iron deficit.  However, I have never heard anyone argue that the iron deficit in those regions is anything new or represents any kind of declining trend.  Even if this were true, would it really represent "the single most critical ocean issue"?  I've heard lots of ocean advocates talk about the devastating effects of over fishing, or the rise of toxic flora in response to declining large fauna, coral bleaching from rising temperatures, and ocean acidification.  These are truly critical ocean issues.  This is the first I've heard of the tragic decline in dissolved iron.
