We have almost 8 billion people on the planet, we absolutely need to "focus" on every possible solution that may work.

There are currently over 100 proposed solutions that do actually add up to more than enough sequestration but the conversation needs to change and the disparaging whataboutism needs to end.

If people get apathetic or nihilism sets in nobody will be able to make the changes required.

You can’t use every approach as iron seeding and this both do the same thing and the oceans are finite.

So this isn’t a 1% solution, it’s not even a 0.1% soliton it might be a 0.01% solution. “50,000 tonnes of tephra – a bulk carrier vessel’s worth – offshore could sequester 2750 tonnes of atmospheric carbon dioxide. This, they said, equates to a cost of around £43 per tonne of carbon dioxide sequestered” assuming absolutely zero CO2 was released in the process.

Bulk carriers are quite efficient and could move 50,000 tons ~= 0.4 tons of CO2 per mile in a straight line. Which sounds fine except you can’t simply dump all 50,000 tons 1 mile off shore and expect anything useful to happen. If you can dump on average 50 tons per mile you just released ~400 tons to sequester 2750. And that’s assuming it somehow gets loaded and unloaded without releasing any extra CO2.

You're ignoring that science improves and leads to further discovery.

It's perfectly fine if 0.00000001% of the population spends their lives on something that achieves nothing if a few of these lead to further developments.

[Retric]

0.00000001% of the global population is less than one person.

Which is kind of the issue, we need a significant fraction of the global workforce to solve climate change. Inefficiency is useless because we lack the economic capacity to solve climate change inefficiently.

Busywork is as useful as doing nothing.

What does whataboutism mean here?
