No amount of VC funding trying to rip CO2 from air is going to save us. Stop putting it there in the first place. Carbon tax, regulation on fossil fuels, ...

I think you're looking at a 'yes, and' situation. The IPCC's simulations just sort of assume we not only cut our carbon emissions but come up with some effective form of carbon capture. Without both, our goose is cooked, but we certainly can't rely on carbon capture alone.

Carbon capture technologies tend to cost more carbon to operate than they are able to actually sequester. Currently very much a pipe dream, especially considering that on a worldwide scale, the carbon equation is still overwhelmingly pushing in the worse direction (more carbon being burned, more forests being removed).

I clicked around, but I didn't see. Is there a device that you sell to capture CO2? Does it capture more than the plant I planted in my office?

It's a very vague website, but it almost seems like they're a business that sells the answer to that question? If so - yuck.
