Earth's magnetic field is currently changing dramatically. Is the observed decrease of the dipole moment indicating a future polarity transition? What would be the effects of such a drastic change on system Earth? Can any positive or negative effects on our biosphere or even humans be expected?

This book gives a first overview about the geomagnetic field in general and serves as an introduction into geomagnetism. As the topic of the book covers a wide range of scientific disciplines, the first chapter summarises basic principles of geomagnetism and related fields including a...

This book provides a major synthesis of evidence for past climate variability at the regional and continental scale across Europe and Africa. It focuses on two complementary time-scales, the Holocene (approximately the last 11,500 years) and the last glacial-interglacial cycle (approximately the last 130,000 years). An overview of the climate system of the past has never been attempted before on this scale, and, as such, the volume represents a benchmark for future research.

It is written by an expert group of climate change scientists and presents an insight into past climate...

Concerns about the effects of global climate change have focused attention on the vulnerability of circumpolar regions. Long-term historical data are needed to better understand the magnitude and direction of environmental change related to both natural and anthropogenic causes, as well as to assess patterns of natural variability. The paucity of instrumental data requires that proxy methods be used. The abundance of lakes throughout the Arctic and Antarctic makes paleolimnological approaches especially powerful tools to assist interpretations of environmental change.

The Ancient Human Occupation of Britain Project (AHOB) funded by the Leverhulme Trust began in 2001 and brought together researchers from a range of disciplines with the aim of investigating the record of human presence in Britain from the earliest occupation until the end of the last Ice Age, about 12,000 years ago. Study of changes in climate, landscape and biota over the last million years provides the environmental backdrop to understanding human presence and absence together with the development of new technologies. This book brings together the multidisciplinary work of the project....

Fishes that walk, fishes that breathe air, fishes that look like--and are--monsters from the deep. These and many more strange creatures swim through The Rise of Fishes, John A. Long's richly illustrated tour of the past 500 million years. Long has updated his classic work with illustrations of recent fossil discoveries and new interpretations based on genetic analyses. He reveals how fishes evolved from ancient, jawless animals, explains why fishes have survived on the Earth for so long, and describes how they have become the dominant aquatic life-form. Indeed, to take things a...
