Chapter One

Policy analysts and policymakers continue to search for metaphors to describe the unique complexities posed by climate change. According to economist William Nordhaus, "If global warming is the mother of all public goods, it may also be the father of decision making under uncertainty." Other policy analysts have referred to climate change as "perhaps the most hotly debated and controversial area of environmental policy ever" and as "one of the most complex challenges that the human race has ever created." In the final days of a federal government career that spanned five decades and included a leading role in many foreign and domestic policy challenges during thirty years in the U.S. Senate, Republican John Warner of Virginia put it more simply: "Without question, this is the most complex problem I have ever faced." Most of those comments were uttered prior to the tumultuous climate policy events of 2009-10, which included prolonged political combat over dauntingly complex legislative proposals before Congress, fallout over revelations from hacked e-mails that raised questions about the integrity of some high-profile climate scientists, and the melodramatic albeit largely inconclusive Copenhagen climate summit.

The discovery that accumulating levels of carbon dioxide, methane, and other gases in the atmosphere could cause a "greenhouse effect" that both elevated global temperatures and disrupted the climate is not new, though its saliency has grown markedly in recent years. In the United States, "rapid climate warming" first arose as an issue for the Domestic Policy Council in 1976, as the Gerald Ford administration responded to concerns raised by counterparts in the Soviet Union. Ronald Reagan signed the first federal climate change legislation, the Global Climate Protection Act (P.L. 100-204), into law in 1987. This authorized the State Department to develop an approach to address global warming and established an intergovernmental task force to develop a national strategy. One year later, governors in California (George Deukmejian) and New Jersey (Thomas Kean) signed the first of many state laws designed to respond to climate change, none of which were capable of "solving" the problem or reversing the threat of climate change. But they initiated a process of "greenhouse governance" that has reached new prominence in the twenty-first century.

A domestic path to policy exploration was also established in other national and subnational capitals and moved rapidly into the arena of international policy. Well before the 1997 Kyoto Protocol to the United Nations Convention on Climate Change, which has triggered much controversy and proven such an abject failure of global governance, international agreements on different aspects of climate change were reached. The United States has been a participant in the vast majority of those agreements. In fact, it was among the first of more than 170 nations to ratify the 1992 UN Framework Convention on Climate Change, which formally pledged to attain "stabilization of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system."

Between the first indicators of concern and the December 2009 United Nations Climate Change Conference in Copenhagen, it is impossible to calculate how much has been said and written about this topic. But we clearly know much more about climate change than in prior decades, and the vast preponderance of relevant evidence from the natural and physical sciences indicates a diverse and alarming set of threats to future generations. Former U.S. vice president Al Gore won the 2007 Nobel Peace Prize for his advocacy on this issue in his post-political career, during which he produced an award-winning film on climate change. Gore shared that award with a veritable army of international climate scientists, known as the Intergovernmental Panel on Climate Change (IPCC), which has brought new focus to what we know about this issue from virtually every discipline in the natural and physical sciences. The ongoing IPCC project remains only one piece of a massive effort that involves the work of countless scientists from around the world. For example, in November 2008 the American Geophysical Union, an international body of 50,000 members who study the earth and its environment, presented a number of major new studies on climate change, ranging from ice-melting patterns to temperature trends. This ever-growing body of scientific analysis has been explored in the hundreds of congressional hearings on climate science held between 1975 and 2009. It resonates with research findings from leading scholars on every continent, creating a consistently disturbing portrait of a staggering challenge. Although policy responses to climate change vary markedly, no national government in the world disputes the core scientific findings. Even the histrionics surrounding "Climategate" and the sophisticated effort to use a select set of purloined e-mails to challenge the existence of human-induced climate change do not reverse the veritable avalanche of evidence on this issue. That said, the best scientific practice remains limited in its ability to predict the future of the planet with any degree of exactitude. That leaves policymakers with considerable uncertainty as they weigh various strategies to reduce greenhouse gas emissions and evaluate the possible impact of the steps taken on global temperatures in future years and future decades.

While the community of natural and physical scientists has weighed in intensively on this issue, more modest contributions have emerged from the social and policy sciences. Within those disciplines, economists have clearly been the most active players on climate change, as reflected in a large body of publications and in active engagement in congressional and state legislative policy hearings and formal reports such as the 2006 Stern Review on the Economics of Climate Change. They have played a valuable role in shaping policy options and generally making the case in favor of market-based approaches, such as those that would allow for the trading of emissions among regulated parties or taxing directly the carbon content of fossil fuels. But economic analyses often confront serious limitations, such as weighing the most efficient strategy against political and institutional realities and constraints.

Other social science disciplines have been far more marginal players, including political science and allied fields that address public management and public policy concerns. A content analysis of the leading political science and public management journals over the past decade suggests a rather stunning absence of scholarly engagement on the topic of climate change. For example, between 1998 and 2009, the twenty-seven top-ranked public management journals published in English produced only a pair of articles on the application of management theory to the challenge of climate change. In more than 400 congressional hearings on climate change between 1975 and 2009, only two political science or public management scholars appear to have ever testified on climate change, in contrast to the far more substantial participation from economists, legal analysts, scholars in numerous natural or physical science...
