PUMPING aerosol particles into the atmosphere to create a sunshade could take a heavier toll on solar power generation than expected. For every 1 per cent of the sun’s rays deflected into space, the average output of solar systems that rely on direct sunlight would drop by 4 to 5 per cent, says Daniel Murphy at the US National Oceanic and Atmospheric Administration in Boulder, Colorado. Geoengineers propose scattering 1 to 2 per cent of sunlight. Aerosols scatter the light that hits them,
