Article

Uncertainty abounds in issues related to climate science and climate changes, the impacts of those changes, and the efficacy of strategies that might be used to mitigate or adapt to change. There are, however, a few things about which we can be quite certain. There are also a number of things about which many people are certain, but should not be.

Certain and uncertain climate science

Despite the continued efforts of skeptics motivated by a desire for attention or short-term economic interests (Oreskes and Conway 2010), we can be certain about a number of basic facts: human activities have resulted in dramatic increases in the atmospheric concentration of carbon dioxide and a number of other greenhouse gasses; those increased concentrations are changing the climate and will continue to do so; one of those changes will be average warming on a planetary scale. Another unambiguous consequence of rising atmospheric concentrations of carbon dioxide will be the continued acidification of...

Acknowledgments

Preparation of this paper was supported by the Center for Climate and Energy Decision Making (CEDM) at Carnegie Mellon University under a cooperative agreement with the National Science Foundation (SES-0949710). I thank my many collaborators who have helped me in the evolution of my thinking about these matters, most notably Hadi Dowlatabadi, Max Henrion and David Keith.
