Survey Finds Public Support for Small-Scale Solar Geoengineering Tests

A government-backed report found that members of the British public support small-scale testing of solar radiation modification techniques that could serve as a backup option if greenhouse gas emissions are not sufficiently reduced. The survey examined attitudes toward approaches that would reflect a portion of incoming sunlight away from Earth.

Respondents indicated they would accept such methods only if deployed at limited scale and only if conventional emissions cuts prove inadequate.

Participants emphasized that any experiments should remain small and reversible. They expressed willingness to consider the approach solely as an emergency measure rather than a primary climate strategy. The report did not detail specific technologies or locations for potential tests. It also did not address regulatory or funding requirements for carrying out such experiments.
