The Earth's medieval magnetic field 1 Citation Science News : A report given at the American Geophysical Union meeting in Toronto, Canada last week suggests that scientists have discovered a way to measure the Earth's magnetic field from 1000 years ago. Geophysicist Annick Chauvin from the University of Rennes, France, and her colleagues have analyzed samples of bricks and mortar from 9th and 10th century French buildings. They suggest that the Earth's magnetic field at the buildings locations peaked in 840 A.D. and measured about 70 m, technorati.com

Climate model raises global temperature predictions 1 Citation Washington Post : If an unusually detailed computer simulation at the Massachusetts Institute of Technology has it right, global warming in this century is on track to be about twice as bad as predicted six years ago. The MIT model is said to be the only one that incorporates among its variables possible changes in economic growth and other human activities and draws on peer-reviewed science on the climatic effects of atmospheric, oceanic and biological systems. After running the model 400, technorati.com

1 Citation According to an investigation headed by the U.S. Geological Survey (?USGS?), the U.S. Gulf of Mexico contains very thick and concentrated gas-hydrate-bearing reservoir rocks which have the potential to produce gas using current technology. Gas hydrate, a substance comprised of natural gas and water, may be a significant new energy source to meet future energy needs. The investigation team consisted of the U.S. Department of Energy (DOE), USGS, U.S. Minerals Management Service (MMS) and a group, technorati.com
