The United States should lead an international effort to prohibit the use of solar geoengineering, a senior fellow at the American Enterprise Institute, Roger Pielke Jr., told members of Congress on Sept. 16.

Pielke testified before the House Oversight and Government Reform Subcommittee on Delivering Government Efficiency during a hearing on weather manipulation, specifically cloud-seeding and geoengineering.
