1. Environmental and Natural Resource Economics 2 nd ed. Jonathan M. Harris Data Updates for 2008 Copyright © 2008 Jonathan M. Harris

2. Notes on Data Updates Resource and environmental issues are subject to rapid change. Since publication of the second edition of Environmental and Natural Resource Economics in 2006, there have been a number of significant developments. Many of these are in the area of climate change, leading to a complete update of Chapter 18 on Global Climate Change, available as a module, The Economics of Global Climate Change, at: http://ase.tufts.edu/gdae/education_materials/modules.html This module can be substituted for Chapter 18; new data and figures from the module are in the Powerpoint file Economics of Global Climate Change Figures and Tables at: http://ase.tufts.edu/gdae/publications/textbooks/ENREupdate.html http://ase.tufts.edu/gdae/education_materials/modules.html http://ase.tufts.edu/gdae/publications/textbooks/ENREupdate.html Other significant areas of change are resource and energy prices. After a long period of stability or decline, many resource prices turned sharply upward in 2006-2008. Some of these price changes are reflected in this update, along with recent energy use trends and projections.
