Acidification (from CO2) and temperature (from CO2) rise would continue to lead to collapses of fish stocks even if we stopped trawling the oceans.
Replacing the first 30% of fossil fuel usage is hard/slow. At some point, it will become much easier/quicker... because the economics will be favourable.
The last 30% of fossil fuel will be hard/slow. Fossil fuel burning use cases that for different reasons are hard to replace. For these, exhaust capture makes sense.
All I'm predicting is that carbon reduction will follow a path. Slow, then fast, then slow again. At that late point, exhaust capture may be mandatory... I would even say probably.
But the team is interesting indeed. Incidentally, there's an online SSC meetup with Jaan Tallinn as guest, _today_: https://www.lesswrong.com/events/jQQYCdtiH5d3CtrNC/jaan-tall...
What he is qualified for is running this sort of effort. I just don't know what to call this sort of effort.
Viento is a ‘moonshot’ nonprofit pioneering targeted weather security... by combining big data, forecasting breakthroughs and AI directed weather interventions... framed as "break glass in case of climate emergency."
So... I don't like the idea. I do however, like the way he puts together moonshot projects, generally. Maybe this will evolve into something better. It's useful to have 0.X% of people working on tech, to be doing it in an environment that isn't standard academia or big tech.
