... iron on a large scale should actually cool the planet directly, in addition to increasing C drawdown, because all those liddle phytos release DMS (dimethyl suphide) which is a water nucleator i.e. a rainmaker. Unproductive areas are far from land (see above) and the most productive ones are where ...
