Bravo for accurately addressing the most taboo subject I have ever encountered. "Blocking the sun with solar shades" to quote another person offering feedback, has been going on for about twenty years, and has been rampant in southern California in the last two years. Most people haven't noticed yet. Real clouds are a rare commodity where I live...and I live in the heart of a forest. Yes, geoengineering is already widespread. And it is already widespread in the skies above us. As for blocking photosynthesis and making the cycle even worse...yes, that is correct. And finally...yes, it is absolutely time to quit pretending this isn't already happening.
