New Mexico S Ice Ages

The Late Pennsylvanian was a time of ice ages and associated climate dynamics. A major reduction in Gondwana ice-volume was followed by a prolonged period of relative global warmth, culminating in the last great ice age of the late Paleozoic. It also was a major turning point in the evolution of life on land, when the coal forests of the Middle Pennsylvanian gave way to new kinds of Late Pennsylvanian wetland vegetation, and new kinds of animals appeared. Changes in the terrestrial biota began during the Middle Pennsylvanian, accelerating and proceeding in a spatially complex manner throughout the Late Pennsylvanian. The Late Pennsylvanian is thus a laboratory for studying environmental changes in a glacial world, and for assessing coeval biotic changes, in part to establish the possible links between the two. No book has been dedicated to this time interval, so this volume fills a gap in our understanding of a dynamic Late Pennsylvanian world that is much like the late Cenozoic world.

Ice Age Earth provides the first detailed review of global environmental change in the Late Quaternary. Significant geological and climatic events are analysed within a review of glacial and periglacial history. The melting history of the last ice sheets reveals that complex, dynamic and catastrophic change occurred, change which affected the circulation of the atmosphere and oceans and the stability of the Earth's crust.

It is now the year 2125 and the ice age about which the people on Earth were told is actually starting. The world is in chaos and most of the governments around the world are no longer functioning. The Washburn-Melbanks family, which includes Max and his wife Alice, their two twin daughters, and both sets of grandparents are trying to reach the equatorial region of South America. Max knows that the 'visitors' who came to Earth to tell everyone what was in their near future made a short stop at the equatorial region in the year 2130. If they can get from Minnesota to Columbia and the equatorial region, they may be able to contact the 'visitors' with the hope of being taken to a new planet to which the 'visitors' brought other human beings to try to save the human race. Unfortunately, the going isn't very easy and they have to fight their way through many obstacles before they reach their final destination. Even though they do eventually reach their goal, will they be able to contact the 'visitors' and be taken by them to the new world where other human beings are now living.
