Number: RL33849 Title: Climate Change: Science and Policy Implications Authors: Jane A. Leggett, Resources, Science, and Industry Division Abstract: This report presents an overview of the science of climate change and its potential impacts. It provides highlights on the impacts of climate change itself; it does not address the mitigation of climate change (e.g., by controlling greenhouse gas emissions) nor the economic issues associated with it. This report is organized into four topics: Climate change and impacts that have been observed. Forces that are understood to be causing recent climate change. Projections of future climate change and impacts. Implications of climate change science for policy. Pages: 50 Date: May 2, 2007
