Drawing on case studies of past environmental debates such as those over acid rain and ozone depletion, science
policy experts Roger Pielke Jr. and Daniel Sarewitz argue that once next generation technologies are available that make meaningful action on climate
change lower - cost, then much of the argument politically over scientific uncertainty is likely to
diminish.26 Similarly, research by Yale University's Dan Kahan and colleagues suggest that building political consensus on climate
change will depend heavily on advocates for action calling attention to a diverse mix of options, with some actions such as tax incentives for nuclear energy,
government support for clean energy research, or actions to protect cities and communities against climate risks, more likely to gain support from both Democrats and Republicans.
