Hi Mike,
Welcome to EvCforum. Interesting (if a bit lengthy) post. To be honest, I'm having some difficulty separating what you wrote with Lovelock and Margulis' Gaia Hypothesis. There are aspects that are extremely similar. Although they don't focus on ionization/clouds
per se, one aspect of their idea does discuss large-scale hypercycles and feedback loops between airborne "plankton" and climate control. Unfortunately, airborne sampling hasn't as yet yielded the quantities of this plankton that would appear to be necessary for such a cycle.
Could you please condense the differences in your idea and that of Lovelock/Margulis? Maybe by using bullets to show specific differences?
For reference, I'm basing my comparison on Margulis' 2000 "Symbiotic Planet", which although a tad rambling has the benefit of being a short explanation, and Lovelock's larger 1987, "Gaia: a New Look at Life on Earth".
