People need to keep in mind how rare CO2 is in the atmosphere. It currently is at around 420 ppm and was at around 100 ppm less in the 60s. CO2 is a miniscule part of the atmosphere, which is why large relative changes are caused by human activity.

To remove 10ppm of atmospheric CO2 from the atmosphere (which would do nothing to sustainably lower CO2 in the atmosphere) would require processing 10ppm of the entire atmosphere. That is one in 100.000 parts of the atmosphere. The entire atmosphere is around 5x10^18 kg, so we need to process 5x10^13 kg of air. Which is 50 million million (no typo) kilos of air.

The industrial task of doing this unfathomably large and by itself would have no long term Impact.

Human fabricated carbon capture from ambient air is a complete fools errand only promoted by the scientific illiterate or those who benefit from scientific illiteracy. You can essentially just look at the first graph on wikipedia and see that it is never going to work: https://en.wikipedia.org/wiki/Carbon_dioxide_in_the_atmosphe...
