House adopts memorial urging attention to solar geoengineering research and oversight

The Idaho House adopted House Joint Memorial 18 on March 16, which expresses concern about solar geoengineering (solar radiation modification) and urges attention to associated research, governance frameworks and potential risks to soil, water and air.

Sponsor remarks described the scope of geoengineering, referencing stratospheric aerosol injection and academic and policy reports. The sponsor said more than 30 states have proposed or considered legislation related to aspects of geoengineering and cited international research conversations, arguing Idaho should consider protections for natural resources and local decision-making.

Members who spoke in debate recounted personal observations of persistent streaks in the sky and framed the memorial as a call for research and oversight rather than an enactment of policy. The House passed the memorial after dispensation of further reading; language and background materials were placed into the record for members.

The memorial urges federal oversight and attention to research and does not by itself create binding state regulatory authority; any subsequent statutory changes would require separate legislation.

The House recorded the memorial’s passage and directed relevant clerical processing for transmittal.
