The book contains the transcript and images of the science exploration video by Rolf A. F. Witzsche, with the above title at: http: //www.ice-age-ahead-iaa.ca-- The book is a part of the transcripts series. Lead-in The great Ice Age uncertainty is not located in the realm of Ice Age physics, or in our understanding of the principles involved, nor is it located in the lack of evidence. To the contrary, the principles are well understood, the physics is replicated in laboratory experiments, and the evidence that the Ice Age Challenge is real, is monumental. The great uncertainty lies in the court of society's response to what is known and understood and is already evident around the world. Society's response is so faint at the present time that it is almost non-existing. The question of whether there will be a response forthcoming that enables the whole of humanity to live past the onrushing crisis and create itself a bright future for it, for which the potential exists, remains yet to be answered. As I have said, the physics are simple and the physics plainly apparent. We have observed many Grand Solar Minimum events in the past, and large Global Warming events for more than three thousand years. But we saw their amplitude and intervals shrinking. We saw the interglacial climate as a whole, diminishing, measured in ice cores. We also saw the level of solar activity measured in sunspot numbers and isotope ratios, diminishing at an ever-faster rate. Now in more recent time, past the year-2000, we saw even the solar wind diminishing, measured at a rate of 30% per solar cycle, which is still ongoing. Even the 11-year solar cycle itself - the heart beat of the solar system - has slowed, from 11 to 13 years, and is increasing. The climate scene on Earth has thereby become a scene of wide-ranging anomalies, such as blizzards, floods, and droughts. Ironically, what is deemed to be the next sequential Grand Solar Minimum event, anticipated for the 2030/40 timeframe, is not a cyclical event at all that the world will recover from. These events are history. The solar system no longer has the underlying support to recover from its ongoing collapse. While we will experience another Little Ice Age in the near future, the climate collapse towards it, that is already ongoing, has a different cause than the solar minimum events before. This different cause renders the now unfolding Solar Minimum event unrecoverable. This means that the event is not an event itself, but a transition phenomenon in the boundary zone to the start of the next Ice Age that renders the Earth largely uninhabitable for 90,000 years into the future. It is worth repeating that the great uncertainty in all this is not located in the solar collapse process itself, and the corresponding collapse of the climate on Earth. These aspects are certain. The astrophysical processes are fairly predictable with scientific understanding of the principles involved. We have numerous measurements on hand that tell us that we have come to the end of the line of the interglacial world, with enormous consequences looming ahead for society. However, the challenge to master the consequences comes with grand opportunities in its wings for building us a New World with the technological power to avoid the consequences. While all of these factors are certain, our response to them is not. The response is presently a big ZERO. Still, the time remaining to us is our space for repentance, a time to choose life and develop a profound love for the wondrous humanity that we all share and to protect it with the technological power that we have already in the pocket. We need to develop us a new humanist paradigm on this front that inspires us to built ourselves out of the new impending climate crisis, by building us a New World that the Ice Age Climate cannot touch. Only then, when we are committed to this path, will the uncertainty end.

Scientists charged with producing a map of the earth during the last ice age ultimately confirmed the theory that the earth's irregular orbital motions account for the bizarre climatic changes which bring on ice ages. This book tells the story of those periods--what they were like, why they occurred, and when the next ice age is due.

This book studies the history and gives an analysis of extreme climate change on Earth. In order to provide a long-term perspective, the first chapter briefly reviews some of the wild gyrations that occurred in the Earth’s climate hundreds of millions of years ago: snowball Earth and hothouse Earth. Coming closer to modern times, the effects of continental drift, particularly the closing of the Isthmus of Panama are believed to have contributed to the advent of ice ages in the past three million years. This first chapter sets the stage for a discussion of ice ages in the geological recent past (i.e. within the last three million years, with an emphasis on the last few hundred thousand years). The second chapter discusses geological evidence for ice ages – how geologists surmised their existence prior to actual subsurface data that proved the theory. The following two chapters look at ice cores (primarily from Greenland and Antarctica). Chapter 3 discusses how ice core data is processed and Chapter 4 summarizes data obtained from ice cores. Chapter 5 discusses the processing of data obtained from ocean sediments, and summarizes the results, while the following chapter discusses data from other sources, such as "Devil’s Cave." Chapter 7 summarizes the experimental results from Chapters 4, 5, and 6. It provides the foundation for comparison with theories in later chapters. In a perfect world, this data would be totally separate and disconnected from theory. Unfortunately, as the author shows, dating of much of the data was accomplished by "tuning" to the astronomical theory, which introduces circular reasoning. Chapter 8 provides a brief overview of the various theories that have been devised to "explain" the patterns of alternating ice ages and interglacials that have occurred over the past three million years. This serves as an introduction to the following three chapters which presents the astronomical theory in its various manifestations, compare the astronomical theory with data, and then compare other theories with data. Finally, Chapter 12 summarizes what we think we know about ice ages and, more importantly, what we don’t know.

This book provides a new look at the climatic history of the last 2.6 million years during the ice age, a time of extreme climatic fluctuations that have not yet ended. This period also coincides with important phases of human development from Neanderthals to modern humans, both of whom existed side by side during the last cold stage of the ice age. The ice age has seen dramatic expansions of glaciers and ice sheets, although this has been interspersed with relatively short warmer intervals like the one we live in today. The book focuses on the changing state of these glaciers and the effects of associated climate changes on a wide variety of environments (including mountains, rivers, deserts, oceans and seas) and also plants and animals. For example, at times the Sahara was green and colonized by humans, and Lake Chad covered 350,000 km2 – larger than the United Kingdom. What happened during the ice age can only be reconstructed from the traces that are left in the ground. The work of the geoscientist is similar to that of a detective who has to reconstruct the sequence of events from circumstantial evidence. The book draws on the specialisms and experience of the authors who are experts on the glacial history of the Earth. Readership: Undergraduate and postgraduate students studying the Quaternary, researchers, and anyone interested in climate change, environmental change and geology. The book provides a rich collection of illustrations and photographs to help the readers at all levels visualise the dramatic consequences of glacier expansions during the Ice Age.

Cundill History Prize Finalist Longman–History Today Prize Finalist “Meticulous environmental-historical detective work.” —Times Literary Supplement When Europeans first arrived in North America, they faced a cold new world. The average global temperature had dropped to lows unseen in millennia. The effects of this climactic upheaval were stark and unpredictable: blizzards and deep freezes, droughts and famines, winters in which everything froze, even the Rio Grande. A Cold Welcome tells the story of this crucial period, taking us from Europe’s earliest expeditions in unfamiliar landscapes to the perilous first winters in Quebec and Jamestown. As we confront our own uncertain future, it offers a powerful reminder of the unexpected risks of an unpredictable climate. “A remarkable journey through the complex impacts of the Little Ice Age on Colonial North America...This beautifully written, important book leaves us in no doubt that we ignore the chronicle of past climate change at our peril. I found it hard to put down.” —Brian Fagan, author of The Little Ice Age “Deeply researched and exciting...His fresh account of the climatic forces shaping the colonization of North America differs significantly from long-standing interpretations of those early calamities.” —New York Review of Books
