As climate changes, sea-level rise a coastal concern
Posted by Tasley Eastern Shore News: None Given on August 20th, 2012
Tasley Eastern Shore News: Inch by inch along parts of the Atlantic Coast, global climate change is running in what scientists warn is geology’s version of fast-forward -- swamping and eroding beaches, wetlands and farm fields.
Shorelines from North Carolina to Boston are in a “hotspot” for sea-level rise and will see water levels rise at double the rate of most places on the planet, according to the U.S. Geological Survey. The doubling is largely because of a geologic double whammy. Delaware also has the lowest average...

Guardian: Let's say you want to convince an entire province that the pipeline you're planning to run through some of its most treasured natural areas is a great idea. Probably the last thing you'd want to do is suggest that you didn't know what those treasured natural areas look like. And, the chances are, if you did, you'd probably hope not many people heard about it or, say, spread it around on Facebook.

The Effect of Dams on Global Warming
Posted by Environmental News Network: David A Gabel on August 20th, 2012
Environmental News Network: A new study has revealed the under-appreciation that exists for the role dams play in climate change; how the reservoirs behind them can cause surges of greenhouse gases as the water levels go up and down. In a study of the water column at such a reservoir, marine scientists found an astonishing 20-fold increase in methane emissions as water levels were drawn down. Bubbles coming out of the mud and sediment at the bottom were chock full of this potent greenhouse gas.
The role of lakes, reservoirs,...

In Midst of a Drought, Trying to Keep Cargo Moving on the Mississippi
Posted by Washington Post: Juliet Eilperin on August 20th, 2012
New York Times: This ship is making sure that the Big River, shrinking under one of the worst droughts in modern history, stays deep enough. The Potter is scooping this stretch of the Mississippi River’s navigation channel just south of St. Louis, the ship’s 32-foot-wide head sucking up about 60,000 cubic yards of sediment each day and depositing it via a long discharge pipe a thousand feet to the side in a violent, muddy plume that smells like muck and summer. The Army Corps of Engineers has more than a dozen...
