That is far from discussing.
Do you think the political part of the problem will magically go away if there is a viable phase 3 technology that does not contribute more carbon than it captures?
Do you think the politicians will permit it to be used at scale when they have done all possible to slow renewables?
The article discusses this point in the second paragraph.
> We're now in "Phase 2" and stopping climate change requires both emission reduction and removing CO2 from the atmosphere. "Phase 2" is occurring faster and hotter than we thought. If we don't act soon, we'll end up in "Phase 3" and be too late for both of these strategies to work.
