China accounted for 95 percent of the world’s rare-earth production, raising fears that it might exert monopolistic control. Meanwhile, renewable energy technologies that could function without rare earths, particularly photovoltaic technologies, aren’t close to deployment.
Bulletin of Atomic Scientists: DEVELOPMENT AND DISARMAMENT ROUNDTABLE Technology’s role in a climate solution If the world is to avoid “severe, widespread, and irreversible [climate] impacts,” carbon emissions must decrease quickly—and achieving such cuts, according to the Intergovernmental Panel on Climate Change, depends in part on the availability of “key technologies.” But arguments abound against
