A former Trump administration official is arguing that the president and his allies need to start paying attention to global cooling technologies — whether they believe in climate change or not.

Solar geoengineering technologies, which seek to cool the planet by reflecting sunlight away from Earth, could pose a threat to national security, according to a new report from George David Banks, president of the center-right business group American Council for Capital Formation.

“Regardless of how we feel about climate change, regardless of how we feel about the actual deployment [of solar geoengineering], we can’t afford to have another country — especially an adversary — gain dominance over this technology,” Banks said in an interview.
