EARTH: 2012 - The end of the world of just another year of living in harm's way

July 24, 2012
Alexandria, VA - December 21, 2012 - the purported last day of a 5,125-year cycle in the Mesoamerican calendar - has been added to an endless list of days when the world has been expected to end. But what are our real chances of being wiped out by a catastrophic event - the kind that has happened in the past and will inevitably occur again someday? In the August issue of EARTH, we explore four of the most probable global events that could change life on Earth forever.

Near-Earth objects (NEOs), super-eruptions, solar storms and cataclysmic earthquakes all pose serious risks to our planet on a global and regional scale. However, though these threats exist, is it possible to realistically and economically prepare for them all?

Turn trash to treasure when scientists turn nonrecylced waste into low-carbon fuel; discover how fossilized raindrops provide clues to Earth's early atmosphere; and learn about the silver lining of potentially hazardous asteroids all in this month's issue of EARTH.

The American Geosciences Institute is a nonprofit federation of geoscientific and professional associations that represents more than 250,000 geologists, geophysicists and other earth scientists. Founded in 1948, AGI provides information services to geoscientists, serves as a voice of shared interests in the profession, plays a major role in strengthening geoscience education, and strives to increase public awareness of the vital role the geosciences play in society's use of resources, resiliency to natural hazards, and interaction with the environment.

Geoscience Handbook: AGI Data Sheets, 4th (revised) Edition
by J. Douglas Walker and Harvey A. Cohen (Author), Christopher M. Keane and Abigail Howe (Editor)


One of the best-kept secrets in geology is this handy compilation of geological information. The essential reference for geoscientists in the field, office, or lab, The Geoscience Handbook provides quick reference for the key metrics and concepts, as well as short tutorials on subjects that may not be familiar to all geoscientists. The Handbook covers diverse subjects, from geophysics to geologic map symbols to GPS usage, and everything in between! Now in full color, the Handbook uses color photos when possible to better illustrate geology in the real world. New to this printing is the new and revised 2009 Geologic Timescale published by the Geological Society of America!!!!

Petroleum Geoscience: From Sedimentary Environments to Rock Physics

Petroleum Geoscience: From Sedimentary Environments to Rock Physics
by Knut Bjørlykke (Author)


Petroleum geoscience comprises those geoscientific disciplines which are of greatest significance for the exploration and recovery of oil and gas. These include petroleum geology, of which sedimentary geology is the main foundation along with the contextual and modifying principles of regional, tectonic and structural geology. Additionally, biostratigraphy and micropalaeontology, organic geochemistry, and geophysical exploration and production techniques are all important tools for petroleum geoscientists in the 21st century. This comprehensive textbook present an overview of petroleum geoscience for geologists destined for the petroleum industry. It should also be useful for students interested in environmental geology, engineering geology and other aspects of sedimentary geology

Geological Storage of Carbon Dioxide (CO2): Geoscience, Technologies, Environmental Aspects and Legal Frameworks (Woodhead Publishing Series in Energy)
by J Gluyas (Editor), S Mathias (Editor)


Geological storage and sequestration of carbon dioxide, in saline aquifers, depleted oil and gas fields or unminable coal seams, represents one of the most important processes for reducing humankind's emissions of greenhouse gases. Geological storage of carbon dioxide (CO2) reviews the techniques and wider implications of carbon dioxide capture and storage (CCS).

Part one provides an overview of the fundamentals of the geological storage of CO2. Chapters discuss anthropogenic climate change and the role of CCS, the modelling of storage capacity, injectivity, migration and trapping of CO2, the monitoring of geological storage of CO2, and the role of pressure in CCS. Chapters in part two move on to explore the environmental, social and regulatory aspects of CCS including CO2 leakage...
