We are living through a natural disaster that the news is not reporting. The United States is in an intense drought and down here in Texas it's lasted two and a half years. The Colorado river is becoming hypoxic (deoxiginating), the gulf may be irreperably damaged, almost all of our aquifers are contaminated with TCE, a carcinogen, we're draining fossil water without thought that it can never be replaced (referring to the Ogalala) and we now know that at least some of the hydrologist who study the safety of our water our receiving huge bribes from the oil and gas companies to tell us our water is safe. And all that is just a small picture of what is happening just in the US.
We must educate ourselves to pull ourselves out of our bubbles of ignorance. For me this is an attempt to at least keep myself informed. Aug 16

Soil Carbon Sequestration
MAYFLOWER, Ark. (AP) — Crews on Monday removed a damaged piece of pipeline from which thousands of barrels of oil spilled in central Arkansas last month, as investigators try to determine what caused the rupture. The damaged piece of ExxonMobil Pipeline Co.'s Pegasus pipeline is headed to Hurst Metallurgical Research Laboratory in Euless, Texas, for testing, company spokeswoman Kim Jordan said. Officials still haven't said what caused the pipeline to rupture March 29 and spill an estimated 5,000 barrels of oil in Mayflower, a community about 25 miles northwest of Little Rock. ExxonMobil has said the oil spill didn't affect Mayflower's drinking water supply, which comes from a lake about 65 miles away.

Species at top of freshwater food web can indirectly limit buildup of carbon dioxide in the atmosphere Species at top of freshwater food web can indirectly limit buildup of carbon dioxide in the atmosphere By Janet Raloff
W ater security is emerging as an increasingly important and vital issue for the Asia-Pacific region. Perhaps no other resource—other than oxygen—is so intricately linked to human health and survival. However, as the region’s population growth continues to surge, the demand for water is increasing substantially, without a concomitant increase in water resources. Many Asian countries are beginning to experience moderate to severe water shortages, brought on by the simultaneous effects of agricultural growth, industrialization, and urbanization.
The eye of Hurricane Earl in the Atlantic Ocean, seen from a NASA research aircraft on Aug. 30, 2010. This flight through the eyewall caught Earl just as it was intensifying from a Category 2 to a Category 4 hurricane. Researchers collected air samples on this flight from about 30,000 feet over both land and sea and close to 100 different species of bacteria. Jane Peterson / NASA Microbes are known to be able to thrive in extreme environments, from inside fiery volcanoes to down on the bottom of the ocean.
UCLA Engineering's Eric Hoek holds nanoparticles and a piece of his new RO water desalination membrane. Credit: UCLA Engineering/Don Liebig Researchers at the UCLA Henry Samueli School of Engineering and Applied Science today announced they have developed a new reverse osmosis (RO) membrane that promises to reduce the cost of seawater desalination and wastewater reclamation. Reverse osmosis desalination uses extremely high pressure to force saline or polluted waters through the pores of a semi-permeable membrane. Water molecules under pressure pass through these pores, but salt ions and other impurities cannot, resulting in highly purified water.
This “Learning Package on Hydrology” by the National Institute of Hydrology deals with the basic scientific concepts underlying hydrology. In a general sense the package deals with elements of the hydrologic cycle and explains the processes of rainfall, runoff and evapotranspiration and their interaction. The topics covered include precipitation, abstraction from precipitation, streamflow measurement, hydrographs, flood routing, flood control, groundwater, runoff and floods. The package deals with the occurrence, circulation and distribution of water of the earth and earth's atmosphere. Various phases of the hydrological cycle, such as rainfall, runoff, evaporation and transpiration are all non-uniformly distributed both in time and space. Further, practically all hydrologic phenomena are complex and at the present level of knowledge, they can at best be interpreted with the aid of probability concepts.
Water Contamination Fracking/better than coal
by Anonymous • on News • April 12th • Different reports of some UN agencies warn on increasing scarcity of water per capita in many parts of the developing countries. This crises is happening due to population growth which has the highest rate in those countries, as well as the absence of proper sanitation systems and infrastructures.
