alt Hacker NewsEven if it were meaningful, is the proposal to fight global warming to keep dirty ships? That’s an insane strategy.
More realistically, there’s vested interests in existing ships and shipyards not being made obsolete so any minute effect is overhyped as “this is how we solve global warming”.
This reminds me of a conversation I had with an acquaintance - he was convinced that anthropogenic global warming was impossible because a volcanic eruption emits so much CO2 and was completely unwilling to consider evidence that perhaps humans emitting annually 200x more than all volcanoes combined might have an effect.

"Less bad" is still better than "worse"
You want to unthinkingly reject a proposal that makes things better because you can't understand the third order effects and refuse to accept any evidence.
The proposal is the spray purpose made reflective aerosols high in the atmosphere.
We almost certainly will end up doing this, negatives be damned. Even worse it's just a bandaid not a fix.
