Solar radiation modification (SRM) is one potential approach to partially counteract anthropogenic warming by reflecting a small proportion of the incoming solar radiation to increase Earth’s albedo. An international team of researchers (USA – Michigan State University, Stony Brook University, UC Riverside, City University of New York, industry, UT Rio Grande Valley, University of Minnesota, Oak Ridge National Laboratory, University of Tennessee, University of Minnesota, Rutgers University, Cornell University, Canada, Hong Kong) studied the stratospheric aerosol intervention (SAI), a well-studied and relatively feasible SRM scheme that is likely to have a large impact on Earth’s surface temperature. They outlined current gaps in knowledge about both helpful and harmful predicted effects of SAI on ecological systems. Increased collaboration between ecologists and climate scientists would identify a common set of SAI research goals. According to the researchers without this collaboration, forecasts of SAI impacts will overlook potential effects on biodiversity and ecosystem services for humanity…read more.
