Of the three talks we watched, I found Daniel Kammen's talk, "The Future of Energy and Earth," the most compelling. In particular, I found two related points most interesting. First, I found the discussion of how the study of climate change has become dominated by the STEM fields, like physicists, chemists, and engineers. Understandably, most efforts to study climate change have focused on the hard science—discerning the processes and dynamics of the earth's climate and the potential for green technologies. Kammen points out that, while this focus is an important part of the field, the study of climate change has underemphasized the humanities and social sciences. To address the global crisis of climate change, we need a comprehensive climate strategy that pervades society. As such, an interdisciplinary understanding of climate change is crucial. Relatedly, I found the discussion of the psychology of climate change fascinating. The social sciences are key to understanding how society can and will respond to climate change. In particular, the interview mentioned how the developing field of behavioral economics will contribute significantly to the study of climate change. Specifically, behavioral economics will uncover cognitive biases which can be exploited to "nudge" individuals toward climate-friendly behavior. Such nudges can be incredibly effective and may be a central component of a comprehensive, interdisciplinary climate change response plan.
