Photonic cancellation: analogy between the onset of an Ice Age and the onset of a Green Sahara.

Cassandra analyses the similarities between the onset of a Green Sahara and an Ice Age. Both events involve a phenomenon which cancels solar radiation as a source of heat for the planet. A Green Sahara turns solar radiation into chemical bond instead of heat, and an Ice Age reflects solar radiation back into space.
Because of this, if we get it wrong and prevent our technology to keep heating up the planet, if the onset of an ice age occurs, trying to revert it will be much harder than preventing it to start.

That, of course, assuming that we actually are preventing it, and that the very moderate heating we are experiencing is not a very normal and well known event which already happened several times during this interglacial....
