EARTH: 2012 - The end of the world of just another year of living in harm's way
July 24, 2012Alexandria, 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.

Small-Format Aerial Photography: Principles, techniques and geoscience applications by James S. Aber (Author), Irene Marzolff (Author), Johannes Ries (Author) As the need for geographical data rapidly expands in the 21st century, so too do applications of small-format aerial photography for a wide range of scientific, commercial and governmental purposes. Small-format Aerial Photography (SFAP) presents basic and advanced principles and techniques with an emphasis on digital cameras. Unmanned platforms are described in considerable detail, including kites, helium and hot-air blimps, model airplanes, and paragliders. Several case studies, primarily drawn from the geosciences, are presented to demonstrate how SFAP is actually used in various applications. Many of these integrate SFAP with ground-based investigations as well as conventional large-format aerial photography, satellite imagery, and other kinds of geographic information. ... |
