10bn tonnes must be captured from the air every year to limit global heating to 1.7C, says Johan Rockström

Problem is this part:

To achieve this through technological means, such as direct air capture, would require the construction of the world’s second biggest industry, after oil and gas, and require expenditures of about a trillion dollars a year, scientists said. It would need to be done alongside much more drastic emissions cuts and could also have unintended consequences.

That makes it incredibly unlikely that this kind of removal will be done.
