Fracking by the numbers, a new study from the Environment America Research & Policy Centre, says: â€œPeople who live close to fracking sites are exposed to a variety of air pollutants including volatile organic compounds (VOCs) such as benzene, xylene and toluene. These chemicals can cause a wide range of health problemsâ€”from eye irritation and headaches to asthma and cancer.â€

Technological advances such as horizontal drilling and hydraulic fracturing (commonly known as â€œfrackingâ€) have resulted in the rapid expansion of unconventional oil and gas extraction from shale and other tight rock formations that had been previously deemed inaccessible or too costly to tap. While these techniques have been used for several decades to extract oil from shale in Texas and elsewhe ... Read More
Both freshwater availability for many millions of people and the stability of ecosystems such as the Siberian tundra or Indian grasslands are put at risk by climate change. Even if global warming is limited to two degrees above pre-industrial levels, 500 million people could be subject to increased water scarcity -- while this number would grow by a further 50 percent if greenhouse-gas emissions ...

2 years on after the Fukushima disaster, workers have encountered another serious problem. The rate of water being used to cool down the reactors is exceeding the available storage capacity threatening a leak in the high strontium concentrated water which would contaminate the ground water of the region. ...

Rare kind of snowflakes cover Moscow
1) What is the story?
Graupel, a rare kind of precipitation, fell upon the city of Moscow. Graupel (or snow pellets) form when super-cooled droplets of water condense on a snowflake. Each snow pellet is about 2-5 mm and the snowflake acts as the nucleus. Graupel is more fragile and oval in shape than hail and normally breaks when touched. Read More
Brahma Chellaney writes in the Washington Times of the rising issues concerning water and how it may become a trigger to wars. Writing that the dangers in water, including scarcity, quality and strain on current systems. Noting that the word rival comes from the word in latin "rivalis" meaning one who uses the same stream. ... Read More
With the popularity of complex, physically based hydrologic models, the time consumed for running these models is increasing substantially. Using surrogate models to approximate the computationally intensive models is a promising method to save huge amounts of time for parameter estimation. In this study, two learning machines [Artificial Neural Network (ANN) and support vector machine (SVM)] wer ... Read More
Delving into the â€œInstitutional Black Boxâ€: Revealing the Attributes of Sustainable Urban Water Management Regimes
This paper is based on the proposition that the transition to sustainable urban water management
has been hampered by the lack of insight into attributes of a sustainable urban water regime. ... Read More
