If we want to meet the 2 degrees goal by any means then given current trends we'll have to start removing net amounts of CO2 from the athmosphere. Of course, it makes most sense to do that once we are already carbon neutral, but once we are there, we should have the technology available for deployment and therefore investing in research right now is a good idea.
