Mother Jones: Attracting almost no attention, Russia may have already conducted the first-ever geoengineering field trial.The journal Russian Meteorology and Hydrologyrecently published a new kind of geoengineering study whose lead author is the journal’s editor, the prominent Russian scientist Yuri A. Izrael.Izrael and his team of scientists mounted aerosol generators on a helicopter and a car chassis, and proceeded to blast out particles at ground level and at heights of up to 200 meters. Then they attempted to measure just how much sunlight reaching Earth was reduced due to the aerosol plume.This small-scale intervention was effective, the Russian scientists say. And in an accompanying article on geoengineering alternatives, Izrael and colleagues note that “Already in the near future, the technological possibilities of a full scale use of [aerosol-based geoengineering] will be studied.”
