A CO2 capture solvent with exceptionally low total costs of capture

The flooding is hardly "water world": https://www.nature.com/articles/s41467-019-12808-z

"Central estimates in the recent literature broadly agree that global mean sea level is likely to rise 20–30 cm by 20503,4,5,6,7,8,9,10. End-of-century projections diverge more, with typical central estimates ranging from 50–70 cm under representative concentration pathway (RCP) 4.5 and 70–100 cm under RCP 8.53,9,10,12, though more recent projections incorporating Antarctic ice sheet dynamics indicate that sea levels may rise 70–100 cm under RCP 4.5 and 100–180 cm under RCP 8.5, and could even exceed 2 m or more in far-tail scenarios4,7,8,11. Via a structured elicitation of opinion, experts now estimate there is a 5 percent chance 21st century sea-level rise will exceed 2 m"

Bad news for East Anglia and the Somerset Levels, and many estuary cities including London will need mitigation work.

#1 thank you for sharing, I was all prepared to come back here and say "20 cm-30 cm is a lot! that puts half of boston underwater!", but it doesn't, not even remotely, and thus is a useful reminder to me I can chill

#2 to be fair to OP, think they're referencing what would happen to humanity as a whole if we _didn't_ have carbon capture, not specifically "water world by 2100", and something I've picked up since moving to Boston from Buffalo is that storm surge has a _much_ more significant effect when you're around so much water. Even the 20-30 cm, once you add a foot or two of storm surge that we get a handful of times a year, floods most of Boston in 2050.
