Geotimes November 2006 Megan Sever	Forest Fires Release Mercury The most familiar source of mercury in the atmosphere is coal plants. But a hidden mercury threat is lurking as Earth warms: peatlands in the boreal forest regions of the Northern Hemisphere.
Geotimes November 2006 Carolyn Gramling	Methane Burps Below the Ice Methane bubbles frozen in the ice of a Siberian lake offer a visible target to scientists seeking to estimate how much methane the lakes emit, now estimated at as much as five times higher than previously thought.
Geotimes November 2006 Kathryn Hansen	Canada's Diamonds Face Old Age Geologists are uncovering the unique origins of Canadian diamonds, and finding not only that they are surprisingly old, but also that they have implications for the timing of Earth's early tectonic processes.
Geotimes November 2006 Carolyn Gramling	Mineral Clock Not Set in Stone Dating a hydrothermal deposit -- a vein containing ore minerals left behind by hot, mineral-rich fluids percolating through rocks -- is a notoriously thorny problem, but a radioactive mineral may now offer a solution.
Geotimes November 2006 Laura S. L. Kong	Guarding Against Tsunamis: What Does It Mean To Be Ready? Despite the implementation of new tsunami warning systems, much work is ahead before the coastal communities of the world can be truly prepared.
Geotimes November 2006 Allyson K. Anderson	A Winding Path to the Energy Hill While energy issues are the subject of continued debate on and off the Hill, they won't necessarily be addressed with legislation at the end of the 109th Congress. Instead, a recently proposed bipartisan bill is expected to hit the Senate floor when the Congress returns from recess.
Geotimes November 2006 Carolyn Gramling	Mark D. Myers: Politics, Pipelines and Permafrost The former head of the Oil and Gas Division of Alaska's Department of Natural Resources is heading back down to the lower 48 to be confirmed as the new director of the USGS.
IEEE Spectrum November 2006 Stephen Barlas	U.S. Climate Technology Plan The U.S. climate technology plan represents the first time that federal spending on greenhouse-mitigation technology has been detailed and combined into a complete plan.
IEEE Spectrum November 2006 Kieron Murphy	Q&A: Paul G. Richards, Nuclear Arms Seismologist An interview with the Mellon Professor of the Natural Sciences at Lamont-Doherty Earth Observatory of Columbia University on the science of detecting and measuring nuclear weapons test explosions.
IEEE Spectrum November 2006 Justin Mullins	The Case of Earth's Incredible Shrinking Field Data hidden in the logbooks of 16th, 17th, and 18th century ships have allowed geophysicists to build a picture of the Earth's magnetic field in the centuries before detailed measurements were possible.
