How much each change to the atmosphere has warmed the world:
Recommended actions to cut greenhouse gas emissions in the near future:

36 kilotons a year. Only short by 6 sig figs. You'd need over a 100,000 of these to reach net zero. And the cost for each ton removed is "closer to $1,000 a ton than $100 a ton". Let's say $500 a ton, which is less than the actual cost. That's $18 million a year for this one facility, and you'd need >$1.8 trillion annual to run all the facilities for net zero. It would become the largest single industry in the world (passing agriculture at $1.3 trillion annually)
It's something that needs to be done eventually, but can't be used to get us to net zero.
So, yeah. Neat, but something for after the transition.
