Low water strands 97 vessels on Mississippi River: USCG

Reuters: The U.S. Coast Guard said on Monday that 97 vessels were stranded by low water on the Mississippi River near Greenville, Mississippi, after it closed an 11-mile stretch of the drought-parched waterway for dredging and to replace missing navigation buoys. The worst U.S. drought in 56 years has left the river there at its lowest point since 1988, a year when a similarly dire drought also stalled commercial traffic on the major shipping waterway. Further north, dredging operations near St. Louis...

Hydropower Dam to Flood Sacred Amazon Indigenous Site

Inter Press Service: The Sete Quedas or "seven waterfalls" on the Teles Pires River, which runs through the Amazon rainforest states of Mato Grosso and Pará in central Brazil, are a spiritual oasis venerated by several indigenous groups. But the 20-metre-high rocky falls are to be covered by a reservoir created by a hydroelectric dam that is to flood an area of 95 square km. "It's a sacred area, our creator and mother. And the 'pajé` (shaman) says it is where the fish lay their eggs," João Kayabi, 52, told...

Hurricanes Get Supercharged by River Mouths

National Geographic: Hurricanes can get supercharged when they hit river mouths, researchers now find. Hurricanes keep alive by converting the warmth of tropical waters into motion. The strong winds they kick up in turn cause surface water heated by the sun to mix with deeper, cooler waters, and that drop in warmth causes hurricanes to weaken. Rivers and rainfall alter this pattern by adding freshwater, which is less dense than saltwater. Therefore, this freshwater sits on top of cold seawater for much the same...

EPA seeks input on ethanol mandate waiver requests

Reuters: The U.S. Environmental Protection Agency on Monday said it has begun weighing requests to suspend the U.S. ethanol mandate, which requires refiners to blend ethanol into gasoline, and is seeking public feedback. The governors of North Carolina and Arkansas asked the agency last week to temporarily waive the U.S. quota on ethanol made from corn, because the worst drought in 50 years has driven corn prices higher and hurt livestock producers who depend on the grain for feed. The EPA asked on...

What’s Causing Extreme Weather?

National Geographic: and 2011 that routed storms away from drought-prone parts of North America, and a massive high pressure system, known as a heat ridge, that parked itself over the U.S. this summer and refused to budge. But there's more to the story, said John Nielsen-Gammon, state climatologist in Texas, which just went through the worst one-year drought in its history. It wasn't just bad luck that caused these disasters, he explained. Human-induced global warming was also to blame. (Test your global warming...

Fire crews battle wildfires blazing across West

Reuters: As crops wilt and die in the Balkans, farmers struck down by a particularly harsh drought this year are ruing the region's failure to upgrade irrigation networks and invest in a long-term agricultural strategy. Hot, dry weather in eastern and southern Europe has piled pressure on world grain markets already reeling from huge drought damage in the United States. The toll in Bosnia, where surface soil temperatures in the south have hit 47 degrees Celsius (116 Fahrenheit), is estimated at almost...

US drought will lead to inflation and higher food prices, says report

Guardian: America's severest drought in half a century will push up inflation and put a fresh obstacle in the path of the struggling global economy, one of the UK's leading banks has warned. Karen Ward, senior global economist at HSBC, said sharp increases in the cost of wheat, corn and soya beans came at a time when growth was slowing but said the weakness of wage pressure meant there was no need for central banks to raise interest in response to a higher cost of living." Blistering heat in the US has...
