SHADED PLANET  Solar geoengineering proposals could combat global warming by injecting reflective particles (blue) into the atmosphere above clouds (gray). By reflecting and scattering light, the particles could cool Earth’s temperature and alter rainfall patterns. But that also could reduce the growth of crops (green).
