I think air capture is an important part of the discussion when we talk about trying to get temps back down later this century, but I have serious doubts about it playing a large role in determining what the peak CO2 concentration will be around the middle of the century. Capture is orders of magnitude more expensive than emissions reductions, and will be for a long time. When you invest in capture, you get lower net emissions and that's it. When you invest in emissions cuts, at least while there's still a lot of low-hanging-fruit, you get the same net effect while also getting a productive asset like a power plant. Totally onboard with research budgets going way up for capture tech, we're 100% going to need it, but later rather than sooner I think.
