People talk about climate change as causing a 1m rise in sea levels. Averting that kind of economic and population dislocation makes the kind of energy costs being discussed seem like pissing into the ocean.

1m rise is tiny cost wise compared tk the global economy, just look at the Netherlands, who have calculated[1] they'd need to spend under 0.1% of their GDP to get new barriers and flood control in place to counteract 1m sea level rise.

The effects on agriculture are far more severe than sea level rise.

Right but you when you can put all the industry and money into not producing that much CO2 in the first place I'd wager that's far more effective way to having less CO2 in atmosphere than trying to capture it post-factum.

Or just slapping the same CO2 sequestering method at the end of industrial chain that creates CO2 rather than trying to catch it later.
