World Water Monitoring Challenge Launch - March 16-22, 2015

World Water Monitoring Challenge

EarthEcho is excited to be at the helm of the World Water Monitoring Challenge, a water-quality monitoring program for youth across the world. Join them as they kick off the 2015 testing season with hangouts, virtual field trips, and launch events from across the country. Get your classroom ready today: order your own test kits or explore the events already planned around the world at http://earthecho.org/news/wwmc-launch.

From NSF: Monster hurricanes struck U.S. Northeast during prehistoric periods of ocean warming

National Science Foundation

From NSF, 02/11/2015  --  Scientists find clues in sediment deposits on Cape Cod

Intense hurricanes possibly more powerful than any storms New England has experienced in recorded history frequently pounded the region during the first millennium, from the peak of the Roman Empire to the height of the Middle Ages, according to results of a new study.

The finding could have implications for understanding the intensity and frequency of hurricanes the U.S. Northeast may experience in the future.

EARTH Magazine: New Tracers Can Identify Fracking Fluids

EARTH Magazine

From EARTH Magazine  --  Hydraulic fracturing, the natural gas extraction method known popularly as fracking, has been controversial in large part to the concern about groundwater contamination by the fluids used in the process, especially the so-called flowback fluids that re-emerge at the surface from fracking wells and are usually disposed of by waste water fluid injection into other formations. Now, researchers have developed a geochemical method of identifying fracking fluids in the environment.

Press release for students - Water, key to survival of Roman Empire

EGU Planet Press

From EGU  --  Since the Mediterranean region is often very dry, it was not easy to grow food, such as grain (wheat, oats and other cereals), in some parts of the Empire. Yet, the Romans managed to ensure that the people in their cities had enough food all year round. Scientist Brian Dermody wanted to find out how the Empire survived for so long in the challenging environment of the Mediterranean.

EARTH: California - A Profusion of Drought Restrictions with Varying Results

EARTH Magazine

From EARTH Magazine, 01/26/2015  --  At times last year, 100 percent of California experienced moderate to exceptional drought conditions; even after massive storms in December, almost 80 percent of the state was still under extreme drought, the second-worst category. The drought has been ongoing for a few years now, and last year, state and local officials created new drought restrictions designed to mitigate the effects. But whether these restrictions will make a dent in California’s water shortage amid the ongoing and historic drought remains to be seen.

EARTH: The '100-year-flood' fallacy: Return periods misleading in communication of flood risk

EARTH Magazine

From EARTH Magazine  --  You have probably heard of “100-year floods” and “500-year droughts,” and perhaps you’ve seen signposts near rivers showing when the last big flood was or statements about when the last severe drought occurred. But do you really know what those terms mean, or what your likelihood is of experiencing such a hazard in any given year? Probably not, according to Richard Vogel of Tufts University, because although such terms have long helped policymakers and the public try to make sense of severe weather, they may confuse the issue more than clarify it.
