This approach is also risky. We don't know what climate effects might fall out of very fast, very localized changes in the composition of the atmosphere. What's it going to do to the climate if we suck a bunch of carbon dioxide out of the atmosphere in one localized place? Could it change air movement patterns? Cause extreme weather events as the atmosphere moves around to remix itself? I don't know if any modeling has been done on this (or if modeling it is even possible), but I'd be very worried about unintended side effects with the large scale, intensive application of this sort of technology.
