International and Public Affairs originator text Articles 2011 manuscript version English Climate change is more uncertain, more global, and more long-term than most issues facing humanity. This trifecta makes a policy response that encompasses scientific correctness, public awareness, economic efficiency, and governmental effectiveness particularly difficult. Economic and psychological instincts impede rational thought. Elected officials, who cater to and foster votersā€™ misguided beliefs, compound the soft thinking that results. Beliefs must change before unequivocal symptoms appear and humanity experiences the climate-change equivalent of a life-altering heart attack. Sadly, it may well take dramatic loss to jolt the collective conscience toward serious action. In the long run, the only solution is a bottom-up demand leading to policies that appropriately price carbon and technological innovation, and that promote ethical shifts toward a world in which low-carbon, high-efficiency living is the norm. In the short term, however, popular will is unlikely to drive serious action on the issue. Policy makers can and must try to overcome inherent psychological barriers and create pockets of certainty that link benefits of climate policy to local, immediate payoffs. It will take high-level scientific and political leadership to redirect currently misguided market forces toward a positive outcome.
