Geotimes August 2006 Jennifer Yauck	Microbes Reshuffle Earth's Early History Previously, scientists used microfossil evidence to date the earliest eukaryotes to about 1.8 billion years old, and the earliest cyanobacteria to about 2.1 billion years old. Now, geologists present new evidence suggesting both types of organisms existed as early as 2.45 billion years ago.
Geotimes August 2006 Megan Sever	From Hot to Cold in the Arctic For the first time, scientists have recovered direct evidence of what life in the Arctic has been like for the past 56 million years. A new 400-meter-long sediment core is revealing that all in the Arctic has not always been as it seems.
Geotimes August 2006 Jennifer Yauck	Tree Rings Reveal Overestimate in Western Water When a severe drought hit the Colorado River Basin area between 2000 and 2004, people began to question whether current practices for managing the river would be adequate for managing future water demands. One recent study suggests an answer: probably not.
Geotimes August 2006 Wang & Burns	Oregon's Recipe for Mitigating Earthquakes Oregon's recent development of new earthquake safety policies, which include a long-term state-funded grant program to help rehabilitate high-risk public schools and emergency facilities, serves as a good case study for addressing seismic hazards on a community level.
Geotimes August 2006 Steven Quane	It's Not Hairspray: America's Need for Science Education We are facing real and immediate energy and environmental challenges that require genuine and progressive leadership to solve. Greater public understanding of science and sound scientific processes have the potential to transform our society.
IEEE Spectrum August 2006 Paul McFedries	Changing Climate, Changing Language That humans are having a negative effect on the world's climate is almost universally regarded as a fact in scientific circles, but global warming stubbornly remains in the realm of fantasy in some political and business circles.
IEEE Spectrum August 2006	Modeling Toward Accurate Storm Forecasting For the time being, getting the weather right will still require a large dose of good fortune. But continued improvements in our weather predicting capabilities will eventually take the guessing out of storm prediction and bring us to the moment when wagering on the weather will be a safe bet indeed.
IEEE Spectrum August 2006 William Sweet	Climate Emergency If you're still not convinced that global warming is the most urgent and important problem facing the world today, see Al Gore's film An Inconvenient Truth directed by Davis Guggenheim, or if you just can't stand the man, read his book.
IEEE Spectrum August 2006 William Sweet	Yangtze's Power Is Unleashed The last cofferdam -- a temporary structure standing between the waters of the Yangtze River and the main wall of the Three Gorges Dam -- was recently blown up. Three Gorges has likely been the most controversial damn project ever.
IEEE Spectrum August 2006 Robert Gall & David Parsons	It's Hurricane Season: Do You Know Where Your Storm is? Souped-up satellites, supercomputers, and superior science might soon mean you really can trust the weather report.
