Carbon capture remains controversial as well. For a current perspective on this, this Scientific American article, written by a geoscientist, may be of interest:
In any case, even aspiring geoengineers at, say, Princeton need to choose a suitable major. Geoengineering is not available there. This is inconsequential, however, in that physical scientists on the undergraduate level will be well prepared by choosing courses and majors from foundational fields such as geology, chemistry, physics, math and computer science. In Princeton’s case, geological engineering is available as a certificate program.
