The West Without Water Documents The Tumultuous Climate Of The American West Over Twenty Millennia, With Tales Of Past Droughts And Deluges And Predictions About The Impacts Of Future Climate Change On Water Resources. Looking At The Region's Current Water Crisis From The Perspective Of Its Climate History, The Authors Ask The Central Question Of What Is Normal Climate For The West, And Whether The Relatively Benign Climate Of The Past Century Will Continue Into The Future. The West Without Water Merges Climate And Paleoclimate Research From A Wide Variety Of Sources As It Introduces Readers To Key Discoveries In Cracking The Secrets Of The Region's Climatic Past. It Demonstrates That Extended Droughts And Catastrophic Floods Have Plagued The West With Regularity Over The Past Two Millennia And Recounts The Most Disastrous Flood In The History Of California And The West, Which Occurred In 1861-62. The Authors Show That, While The West May Have Temporarily Buffered Itself From Such Harsh Climatic Swings By Creating Artificial Environments And Human Landscapes, Our Modern Civilization May Be Ill-prepared For The Future Climate Changes That Are Predicted To Beset The Region. They Warn That It Is Time To Face The Realities Of The Past And Prepare For A Future In Which Fresh Water May Be Less Reliable. -- Publisher's Website.

The West without Water documents the tumultuous climate of the American West over twenty millennia, with tales of past droughts and deluges and predictions about the impacts of future climate change on water resources. Looking at the regions current water crisis from the perspective of its climate history, the authors ask the central question of what is normal climate for the West, and whether the relatively benign climate of the past century will continue into the future. The West without Water merges climate and paleoclimate research from a wide variety of sources as it introduces readers to key discoveries in cracking the secrets of the regions climatic past. It demonstrates that extended droughts and catastrophic floods have plagued the West with regularity over the past two millennia and recounts the most disastrous flood in the history of California and the West, which occurred in 186162. The authors show that, while the West may have temporarily buffered itself from such harsh climatic swings by creating artificial environments and human landscapes, our modern civilization may be ill-prepared for the future climate changes that are predicted to beset the region. They warn that it is time to face the realities of the past and prepare for a future in which fresh water may be less reliable.

Looking at the region’s current water crisis from the perspective of its climate history, the authors ask the central question of what is "normal" climate for the West, and whether the relatively benign climate of the past century will continue into the future.

Droughts over the central United States (US) are modulated by sea surface temperature (SST) variations in the eastern tropical Pacific. Many models, however, are unable to reproduce the severity and spatial pattern of the “Dust Bowl” drought of the 1930s with SST forcing alone. We force an atmosphere general circulation model with 1930s SSTs and model‐generated dust emission from the Great Plains region. The SSTs alone force a drought over the US similar to observations, but with a weaker precipitation anomaly that is centered too far south. Inclusion of dust radiative forcing, centered over the area of observed wind erosion, increases the intensity of the drought and shifts its center northward. While our conclusions are tempered by limited quantitative observations of the dust aerosol load and soil erosion during this period, our study suggests that unprecedented atmospheric dust loading over the continental US exacerbated the “Dust Bowl” drought. Documents the tumultuous climate of the American West over twenty millennia, with tales of past droughts and deluges and predictions about the impacts of future climate change on water resources. This book demonstrates the extended droughts and catastrophic floods that have plagued the West with regularity over the past two millennia.
