As geoengineer advocates enter Trump administration, plans advance to spray sun-reflecting chemicals into atmosphere
Harvard engineers who launched the world’s biggest solar geoengineering research program may get a dangerous boost from Donald Trump, environmental organizations are warning.
Under the Trump administration, enthusiasm appears to be growing for the controversial technology of solar geo-engineering, which aims to spray sulphate particles into the atmosphere to reflect the sun’s radiation back to space and decrease the temperature of Earth.
