The Real Old Salt @ 54:

Thank you for the link to the article “Walking the Plank-ton”. I read the article and found it interesting.

I’m inclined to agree that the false assertion “global warming is killing the ocean’s plankton” is probably the next part of the global warming scam (the usual suspects from the Left are promoting this). However I still suspect that a decline in the ocean’s phytoplankton maybe the real reason why the atmosphere’s carbon dioxide has been increasing.

We are fouling up the ocean’s ecosystem. Major fish populations have crashed and wiped out entire industries, e.g. Icelandic cod, sardines in Monterey Bay, etc. Phytoplankton are microscopic creatures and live near the ocean’s surface (they’re very susceptible to poisoning). The comment about causing a plankton bloom through introduction of pulverized rust is interesting. What’s the chemical reaction that’s benefiting the phytoplankton? I’m not a chemist but my suspicion is the rust is changing the level of dissolved oxygen in the water. A quick search of the web revealed the following on this specific topic:
