Climeworks' technology is the real deal, and needs to thrive. The only good CCS is 100% carbon negative and sequesters the carbon in chemically stable forms. This is it, and we need more. Petroleum industry CCS is a scam, but Climeworks is not that.

Disclaimer: I'm biased because I'm Swiss and so is this technology.

We hackers like to believe there is a technological solution for everything. These projects feed that delusion. Massive reductions and degrowth are hard for us to accept. This article somewhat fairly explains how extremely impractical and unlikely carbon capture technologies will be. The investments in the technology and the PR around them serve more to feed the delusion and keep us burning as usual.

I think you can forgive people for wanting to look for solutions that don't require millions/billions of deaths, as that's the only way you'll see the level of change necessary. It will happen naturally over time as economic levels rise and reproduction rates drop below sustaining. But that will take centuries and lots of resources, so I'm doubtful that is what you are proposing.

Great insight as to why we shouldn’t stop ramping renewables deployments. You need not only cover current electrical demand, but demand growth over time, transportation, HVAC, and all of the energy needed to sequester excess atmospheric CO2 emitted during human industrialization (>1000 gigatonnes based on 280ppm atmospheric CO2 pre industrialization and 420ppm current state).

Burning ancient sunlight is expensive.

Burning as usual is clearly not sustainable. If you think massive degrowth is the only way out then I’m afraid we’re totally fucked.

Massive emissions reductions can also be paired with CDR to have even more impact since reductions alone — basically no matter how steep at this point — are not going to get us to where we need to be.
