Interesting to read that the floods could cause invasive species to invade the Colorado river and its tributaries. Most birds, Audubon notes, are safe (they can fly away, duh), BUT, some species may have been trapped. Click to find out how.
The United States Geological Survey (USGS) is moving to create a registry of climate change vulnerability to better protect wildlife, ecosystems and dams.
The registry will collect and display information on climate change adaptation projects underway across the country, Laura Thompson, a biologist with the USGS National Climate Change and Wildlife Science Center, told The Hill. It will pool from federal, state, local and tribal governments, she said.
It comes amid a second-term climate change push by President Obama. The president is leaning on federal agencies to address the issue, and part of his plan calls for greater collaboration with state and local governments.
The noticeto gather information for the registry will be filed in Wednesday’s Federal Register.
The intent of the registry, Thompson said, is to improve planning as governments embark on climate change mitigation efforts to protect species, habitats and water infrastructure.
The Bureau of Reclamation today announced it will reduce for the first time ever Colorado River water deliveries from the Lake Powell reservoir downstream to Lake Mead, which provides nearly all of Las Vegas’ water.
Worst drought on record impacting cities in the southwest, including millions in Las Vegas. Demand continues to rise. The Colorado River water wars have begun. Via
BEIJING (Reuters) - China’s environment ministry has given the go-ahead for the construction of what will become the country’s tallest hydroelectric dam despite acknowledging it will have an impact on plants and rare fish.
The dam, with a height of 314 meters (1,030 feet), will serve the Shuangjiangkou hydropower project on the Dadu River in southwestern Sichuan province.
To be built over 10 years by a subsidiary of state power firm Guodian Group, it is expected to cost 24.68 billion yuan ($4.02 billion) in investment.
The ministry, in a statement issued late on Tuesday, said an environmental impact assessment had acknowledged that the project would have a negative impact on rare fish and flora and affect protected local nature reserves.
Developers, it said, had pledged to take “counter-measures” to mitigate the effects.
China aims to raise the share of non-fossil fuels in its energy mix to 15 percent by 2020, up from 9.4 percent in 2011. Hydropower is expected to make the biggest contribution.
It has vowed to speed up construction of dams in the 2011-2015 period after slowing it down following the completion of the controversial Three Gorges project in 2005.
Environmental groups silent. Dam will be 1,000 feet tall, about the same height as the Eiffel Tower.
Above, the gigantic Jirau Dam is one of 34(!) hydroelectric dams being built in the Amazon by Brazil. Thousands of people and dozens of communities and towns will be flooded by the dams. Meanwhile, environmentalists are left out of negotiations.
When it is completed in 2015, the Jirau hydroelectric dam will span the Madeira River, feature more giant turbines than any other dam in the world and hold as much concrete as 47 towers the size of New York’s Empire State Building.
And then there are the power lines, draped along 2,200 km of forests and fields to carry electricity from the middle of South America to Brazil’s urban nerve center, Sao Paulo. Still, it won’t be enough.
The Jirau Dam and the Santo Antonio complex that is being built a few kilometers downstream will provide just 5 percent of what government energy planners say Brazil will need in the next 10 years.
So the country is building more dams, many more, courting controversy by locating the vast majority of them in the world’s largest and most biodiverse forest.
A week after the dumping of at least 20,000 gallons of toxic and potentially radioactive fracking waste into a storm drain that empties into a tributary of the Mahoning River in Youngstown, Ohio, by Hard Rock Excavating, state regulators have yet to disclose information about the quantity of waste and the chemicals involved.
Dang. Most storm drains dump untreated run-off into a river, pond, lake, or some other body of water. Storm drain infrastructure drains roads and parking lots of rain water and snow melt.
My understanding is that it is illegal under the Clean Water Act (e.g., the EPA) to dump toxic chemicals into these drains since fish, riparian mammals, amphibians, and reptiles, birds, kids, swimmers, and farmers use surface waters on a regular basis.
If the above is correct (I’m skeptical), that frackers are dumping chemical-waste-water into storm drains, holy shit - Ohioans downstream are in for a big surprise…
A stretch of China’s mighty Yangtze River, near the city of Chongqing, has turned an alarming shade of red…
Indeed, on 7 September the Chongqing Environmental Protection Agency noted on its website that a water-quality monitoring centre on the Yangtze had detected very high concentrations of silt in the river. The agency says that torrential rain in the upper Sichuan province caused huge amounts of silt to wash into the Yangtze. It also says that the water does not contain hazardous or noxious substances.
Scientists interviewed by Nature say that it is unlikely, although not impossible, that the colouring is a result of an algal bloom. Sudden growths of algae, fed by fertilizer run-off (a process known as eutrophication), can sometimes produce blooms of brownish diatom algae in rivers, says Sergi Sabater, a limnologist at the Catalan Institute of Water Research in Spain, who carries out research in river ecology. Such ‘red tides’ of algae are sometimes observed in warm, shallow and nutrient-rich seas.
Exxon Mobil announced a new oil spill in the Niger Delta today. There’s nothing beyond the announcement now—no word on how much is spilled, if people are hurt, etc. But with the US oil presence in Nigeria in the news for moment, it’s a good time to flag this documentary.
Sweet Crude is the well told story of Big Oil in the Niger Delta (only a 50-year old phenomena), and the local resistance to it. If you’ve ever wanted to know how protest struggles evolve to include guns, and how we see the side we come to see, here’s one way.
