Climate change is today’s news, but it isn’t a new phenomenon. Centuries-long cycles of heating and cooling are well documented for Europe and the North Atlantic. These variations in climate, including the Medieval Warm Period (MWP), AD 900 to 1300, and the early centuries of the Little Ice Age (LIA), AD 1300 to 1600, had a substantial impact on the cultural history of Europe. In this pathfinding volume, William C. Foster marshals extensive evidence that the heating and cooling of the MWP and LIA also occurred in North America and significantly affected the cultural history of Native peoples of the American Southwest, Southern Plains, and Southeast.

Correlating climate change data with studies of archaeological sites across the Southwest, Southern Plains, and Southeast, Foster presents the first comprehensive overview of how Native American societies responded to climate variations over seven centuries. He describes how, as in Europe, the MWP ushered in a cultural renaissance, during which population levels surged and Native peoples substantially intensified agriculture, constructed monumental architecture, and produced sophisticated works of art. Foster follows the rise of three dominant cultural centers—Chaco Canyon in New Mexico, Cahokia on the middle Mississippi River, and Casas Grandes in northwestern Chihuahua, Mexico—that reached population levels comparable to those of London and Paris. Then he shows how the LIA reversed the gains of the MWP as population levels and agricultural production sharply declined; Chaco Canyon, Cahokia, and Casas Grandes collapsed; and dozens of smaller villages also collapsed or became fortresses.

The contiguous river basins that flowed in Tlaxcala and San Juan Teotihuacan formed part of the agricultural heart of central Mexico. As the colonial project rose to a crescendo in the sixteenth and seventeenth centuries, the Indigenous farmers of central Mexico faced long-term problems standard historical treatments had attributed to drought and soil degradation set off by Old World agriculture. Instead, Bradley Skopyk argues that a global climate event called the Little Ice Age brought cold temperatures and elevated rainfall to the watersheds of Tlaxcala and Teotihuacan. With the climatic shift came cataclysmic changes: great floods, human adaptations to these deluges, and then silted wetlands and massive soil erosion.

This book chases water and soil across the colonial Mexican landscape, through the fields and towns of New Spain’s Native subjects, and in and out of some of the strongest climate anomalies of the last thousand or more years. The pursuit identifies and explains the making of two unique ecological crises, the product of the interplay between climatic and anthropogenic processes. It charts how Native farmers responded to the challenges posed by these ecological rifts with creative use of plants and animals from the Old and New Worlds, environmental engineering, and conflict within and beyond the courts. With a new reading of the colonial climate and by paying close attention to land, water, and agrarian ecologies forged by farmers, Skopyk argues that colonial cataclysms—forged during a critical conjuncture of truly unprecedented proportions, a crucible of human and natural forces—unhinged the customary ways in which humans organized, thought about, and used the Mexican environment.

This book inserts climate, earth, water, and ecology as significant forces shaping colonial affairs and challenges us to rethink both the environmental consequences of Spanish imperialism and the role of Indigenous peoples in shaping them.

Only in Texas could a snowstorm pelt the Panhandle at the very moment abrasive dust is scouring the Permian Basin while searing heat is wilting the Winter Garden region in the south. The state’s large size and central location within North America subject it to a great variety of weather occurrences. Texas state meteorologist George W. Bomar has been observing Texas weather for nearly half a century, and in Weather in Texas, he provides the essential guide to all of the state’s weather phenomena.

Writing in lively layman’s language, Bomar fully explains both how the weather works and how Texans can prepare for and stay safe during extreme weather events. He describes the forces that shape Texas weather from season to season, including the influence of tropical cyclones, frontal boundaries, El Niño, and the polar jet stream. Bomar puts specific weather events in historical context, using a ranking system to illustrate how recent droughts, snowstorms, hurricanes, flash floods, and tornadoes compare with those of previous generations. He also includes comprehensive tabulations of weather data for every area of Texas, quantifying what constitutes “normal” weather, as well as the extreme limits of variables such as low and high temperatures, rain days, snow accumulations, and earliest and latest freezes. With everything from the latest science on climate change and weather modification to dramatic stories about landmark weather events, Weather in Texas is a must-have reference for all Texans..
