Nature is fragile, environmentalists often tell us. But the lesson of this book is that it is not so. The truth is far more worrying. Nature is strong and packs a serious counterpunch . . . Global warming will very probably unleash unstoppable planetary forces. And they will not be gradual. The history of our planet's climate shows that it does not do gradual change. Under pressure, whether from sunspots or orbital wobbles or the depredations of humans, it lurches-virtually overnight. —from the Introduction Fred Pearce has been writing about climate change for eighteen years, and the more he learns, the worse things look. Where once scientists were concerned about gradual climate change, now more and more of them fear we will soon be dealing with abrupt change resulting from triggering hidden tipping points. Even President Bush's top climate modeler, Jim Hansen, warned in 2005 that "we are on the precipice of climate system tipping points beyond which there is no redemption." As Pearce began working on this book, normally cautious scientists beat a path to his door to tell him about their fears and their latest findings. With Speed and Violence tells the stories of these scientists and their work-from the implications of melting permafrost in Siberia and the huge river systems of meltwater beneath the icecaps of Greenland and Antarctica to the effects of the "ocean conveyor" and a rare molecule that runs virtually the entire cleanup system for the planet. Above all, the scientists told him what they're now learning about the speed and violence of past natural climate change-and what it portends for our future. With Speed and Violence is the most up-to-date and readable book yet about the growing evidence for global warming and the large climatic effects it may unleash.

(Hydraulic Design Series) This document provides technical information and guidance on the hydraulic analysis and design of bridges. The goal is to provide information such that bridges can be designed as safely as possible while optimizing costs and limiting impacts to property and the environment. Many significant aspects of bridge hydraulic design are discussed. These include regulatory topics, specific approaches for bridge hydraulic modeling, hydraulic model selection, bridge design impacts on scour and stream instability, and sediment transport.

"The purpose of this report is to document the response to the oil spill that resulted from the explosion on the Deepwater Horizon mobile offshore drilling unit on April 20, 2010. On scene coordinator report, Deepwater Horizon oil spill, submitted to the National Response Team, September 2010. On November 18, 2010, the National Response Team (NRT) requested submission of an On-Scene Coordinator (OSC) report for the Deepwater Horizon spill to the NRT Response Committee, pursuant to the National Contingency Plan (NCP). The NART's request listed 33 specific topics be addressed in the report. The list of specific topics addressed in the report expanded to 56 to cover additional focus areas of the Federal On-Scene Coordinators (FOSCs)"--Executive summary.

This book reviews the history of the United States-Liberia relations from the early 1820s to 2015, with particular attention paid to the role of the US armed forces. Contrary to most literature on the genesis and development of Liberia, this book demonstrates how US military power has been the primary influence shaping Liberia's history. This includes the role played by the US military in the founding of Liberia, the protection of the country during the European formal colonial era, multiple covert operations in securing US-friendly administrations in Liberia, and direct military interventions when necessary to secure American interests in the region.

Offers an overview of the temperate forest that covers much of North America, describing the three types of temperate forest biomes and the aspects that define them.
