The possibility of climate change raises many economic issues. The potential for such change introduces uncertainty in long-term decisionmaking and results, first, in costs entailed in scientific investigation of the possibility, which may provide concomitant benefits, such as better understanding of the dynamics of climate or of biological responses to natural climate change.
Economic uncertainties include: (1) the costs (or benefits) that could arise if global climate change were to occur, for example through impacts on agriculture or on low-lying areas subject to flooding by sea-level rise; (2) the costs (or benefits) that could result from trying to mitigate climate change impacts, such as building dikes around communities that might be affected by sea-level rise; and (3) the costs (or benefits) that could result from policy decisions to minimize greenhouse gas concentrations, such as measures to curb greenhouse gas emissions (especially CO2) and to offset emissions, such as tree planting. The comparative costs (or benefits) of actions to curb emissions, such as emissions taxes, emissions permits, and technological fixes to reduce emissions of one or more gases, have received particular attention in economics circles.
Attempts to analyze these issues are complicated by disagreements on appropriate frames of reference and analytical methods. Disagreements are particularly acute on the probability of climate change and the possible rate and magnitude of change, on the development and adoption of energy-using technologies by businesses and households with respect to efficiency and alternative energy sources, on how to address inequalities among nations in resource endowment and economic development status, and on what the implications might be for future generations.
Many studies of costs (and benefits) relating to climate change have been prepared, with major differences in assumptions about specific impacts of climate change and measures to mitigate it, as well as those about the evolving impacts of such measures on social and political forces. These disparities result in a wide range of analytic results. The additional readings and the web sites that follow illustrate this wide array some might say, disarray. Researchers and policymakers need to consider with care the assumptions and methods underlying the analyses found in the readings and accessible through the web sites.CRS Products
