Remediation of soil, preventing deforestation, reforestation are all very important options that need to be pursued. Direct capture to storage is a waste of capital (political, talent and financial) and rewards both the oil and gas historic investments and incentivizes them to continue to pursue fossil fuel production. That with it requiring specific geologic formations and on top there is a risk that there are leaks in the formations (e.g. Aliso Canyon gas leak in California).

Oil and gas companies (and many companies) are going to continue to use fossil fuels regardless of whether or not we invest in direct capture. By your logic, I could say that investing in soil remediation also incentivizes people to keep driving their ICE vehicles... The point is that we are almost certainly going to blow past the 1.5 degree C (and likely 2 degree C) mark if we continue to decarbonize at a slow pace. To avoid this fate, we need to do rapidly electrify everything AND we need to remove carbon from the atmosphere. Direct air capture will never be free, but compared to the cost of future negative climate change impacts the cost of direct air capture could be totally justified. At the very least, it is worth investing in the technology to see if it can become a game changer.

  I do think we need to electrify as much as possible but not everything the last 20% is ineffective and quite costly. I get that electrify everything is a great slogan but the reality is that maybe 60-80% makes sense and then after that it because a total cluster. I disagree - and i will continue to say that CCS is a red herring and waste of resources. It has been under development for a considerable amount of time and still has not proven itself. Go look at Alberta's multibillion dollar investments into CCS and how much has not materialized. Deploy technology we already have and invest in viable R&D technology. Renewables, better agriculture, hydrogen based fuels, reforestation, changing cement processes, landfill management, capture biogas from waste water treatment plants and ag facilities, reduce high GWP refrigerant uses in countries that still allow them.... We will blow by 1.5 C if you've been watching this space since the early 2000s we've blown by every single warning that we've put up. Theres a moment in time that is happening right now - we waste our political clout and money on CCS or anything on GeoEngineering and it will be a disappointing future. And no, investing in soil remediation would not incentivize further use of the ICE/fossil fuel burning tech because the oil majors aren't the companies standing to gain from soil remediation (i.e. they haven't spent considerable money funding R&D institutes to evangelize and deploy this tech).

With the excess CO2 we have in the atmosphere generated by humanties addition to fossil fuels, nature itself cannot act fast enough to save us. Over millenia trees, natural carbon weathering and other processes will stabalize conditions but we cannot wait that long. We have to do everything you said and optimize technologies that convert gaseous CO2 into something that can be permanently stored.

  Nature heals faster than we give it credit for, though there is considerable damage being done. Certain species can grow rapidly and remove CO2 from the air. Not saying this isn't a herculean push that requires all efforts - the only efforts I have a difficult time swallowing are CCS and geo-engineering (see other comments for reasoning). I'm all aboard for the others that have been put forward at this point.
