It’s been nearly four decades since scientists first realized that global warming posed a potential threat to our planet. Why, if we knew of the threats way back in the Carter Administration, can’t we act decisively to limit greenhouse gases, deforestation, and catastrophic warming trends? Why are we still addicted to fossil fuels? Have we all just been fiddling for 40 years as the world burns around us? Schneider, part of the Nobel Prize–winning team that shared the accolade with Al Gore in 2007, had a front-row seat at this unfolding environmental meltdown. Piecing together events like a detective story, Schneider reveals that as expert consensus grew, well-informed activists warned ...

Science, technology, engineering, and mathematics (STEM) are cultural achievements that reflect our humanity, power our economy, and constitute fundamental aspects of our lives as citizens, consumers, parents, and members of the workforce. Providing all students with access to quality education in the STEM disciplines is important to our nation's competitiveness. However, it is challenging to identify the most successful schools and approaches in the STEM disciplines because success is defined in many ways and can occur in many different types of schools and settings. In addition, it is difficult to determine whether the success of a school's students is caused by actions the school takes or...
This book examines five rhetorical strategies used by the US coal industry to advance its interests in the face of growing economic and environmental pressures: industrial apocalyptic, corporate ventriloquism, technological shell game, hypocrite’s trap, and energy utopia. The authors argue that these strategies appeal to and reinforce neoliberalism, a discourse and set of practices that privilege market rationality and individual freedom and responsibility above all else. As the coal industry has become the leading target and leverage point for those seeking more aggressive action to mitigate climate change, their corporate advocacy may foreshadow rhetorical strategies available to other fossil fuel industries as they manage similar economic and cultural shifts. The authors’ analysis of coal’s corporate advocacy also identifies contradictions and points of vulnerability in the organized resistance to climate action as well as the larger ideological formation of neoliberalism.
This book constitutes the refereed proceedings of the 4th European Symposium on Research in Computer Security, ESORICS '96, held in Rome, Italy, in September 1996 in conjunction with the 1996 Italian National Computer Conference, AICA '96. The 21 revised full papers presented in the book were carefully selected from 58 submissions. They are organized in sections on electronic commerce, advanced access control models for database systems, distributed systems, security issues for mobile computing, network security, theoretical foundations of security, and secure database architectures.

This is the mcomprehensive and currreference resource on climate change available today. It features forty-nine individual chapters by some of the world’s leading climate scientists. Its five sections address climate change in five dimensions: ecological impacts, policy analysis, international considerations, United States considerations, and mitigation options to reduce carbon emissions. In many ways, this volume supersedes the Fourth AssessmReport of the Intergovernmental Panel on Climate Change (IPCC). Many important developments too recto be treated in the 2007 IPCC documents are covered here. Overall, Climate Change Science and Policy paints a direr picture of the effects of climate change than do the IPCC reports. It reveals that climate change has progressed faster than the IPCC reports anticipated and that the outlook for the future is bleaker than the IPCC reported.
