Climate change mitigation strategies have focused on reductions in carbon dioxide and other long-lived greenhouse gases. Smith et al., investigate the viability of a different strategy, recently proposed by Hansen et al., which focuses on controlling short-lived pollutants such as soot and tropospheric ozone. They conclude that carbon dioxide must remain the primary focus of climate change mitigation strategies.
