the balloon is basically litter, unless they retrieve. The winnebago uses fuel. The balloon made from. Petrochemicals no doubt. The fabrication, pressurization and distribution of the SO2. Seems like this batched approach would on its own might be carbon positive.... negative credits.

it’s the arrogance of these self important idiots that drives me mad. every single one of them is a perfect Dunning-kruger example. all self belief, not even the faintest sense that they might possibly have got it wrong

Just what the world needs: Some dudes with a Winnebago, a tank of sulfur dioxide, and zero scientific credibility selling cooling credits

Well, you know, so very many tech bros. Always thinking they invented the wheel. But the wheel they announce is square-shaped.

SO2 has a short residence time compared to CO2. To sell this (very bad idea) as carbon credits they’d need a plan to keep injecting SO2 for a thousand years or so, not a timescale tech bros are good at, even when they try.
