Abstract:
This paper starts with the question of whether climate change will require a significant reduction of consumption among the richer people in the world, and ends with the most optimistic picture the author can conjure up, of the world in the year 2075. That hopeful picture is of a world in which inequalities – among and within nations – have been substantially reduced. The challenges and adjustments confronting humanity in the coming decades provide an opportunity that could be used to mitigate climate change in ways that can improve the circumstances of the poor. Ecological reasons to reduce throughput of energy and materials in economic systems urge the abandonment of high-consumption life-styles. The 21st century will be an era of many losses, but it is conceivable that societies will successfully make the transition from goals of economic growth, as understood in the 20th century, to goals of maintaining and increasing sustainable well-being.

12. Economists, Value Judgments, and Climate Change: A View From Feminist Economics

Abstract:
A number of recent discussions about ethical issues in climate change, as engaged in by economists, have focused on the value of the parameter representing the rate of time preference within models of optimal growth. This essay examines many economists' antipathy to serious discussion of ethical matters, and suggests that the avoidance of questions of intergenerational equity is related to another set of value judgments concerning the quality and objectivity of economic practice. Using insights from feminist philosophy of science and research on high reliability organizations, this essay argues that a more ethically transparent, real-world-oriented, and flexible economic practice would lead to more strongly objective, reliable, and useful knowledge.

13. The Economics of Inaction on Climate Change: A Sensitivity Analysis

Abstract:
Economic models of climate change often take the problem seriously, but paradoxically conclude that the optimal policy is to do almost nothing about it. We explore this paradox as seen in the widely used DICE model. Three aspects of that model, involving the discount rate, the assumed benefits of moderate warming, and the treatment of the latest climate science, are sufficient to explain the timidity of the model's optimal policy recommendation. With modifications to those three points, DICE shows that the optimal policy is a much higher and rapidly rising marginal carbon price; that higher carbon price has a greater effect on physical measures of climate impacts. Our modifications exhibit nonlinear interactions; at least at low discount rates, there is synergy between individual changes to the model. At low discount rates, the inherent uncertainty about future damages looms larger in the analysis, rendering long-run economic modeling less useful.

14. Can Climate Change Save Lives? A comment on "Economy-wide estimates of the implications of climate change: Human health"

Abstract:
In a recent article in this journal, Francesco Bosello, Roberto Roson, and Richard Tol make the surprising prediction that the first stages of global warming will, on balance, save a large number of lives. Bosello et al. fail to substantiate this remarkable estimate, and they make multiple mistaken or misleading assumptions. They rely on research that identifies a simple empirical relationship between temperature and mortality, but ignores the countervailing effect of human adaptation to gradual changes in average temperature. While focusing on small changes in average temperatures, they ignore the important health impacts of extreme weather events such as heat waves, droughts, floods, and hurricanes. They extrapolate this pattern far beyond the level that is apparently supported by their principal sources, and introduce an arbitrary assumption that may bias the result toward finding benefits from warming.
