Fracking by numbers

Posted by Hadian 322 days ago in Miscellaneous from http://touchstoneblog.org.uk

Fracking by the numbers, a new study from the Environment America Research & Policy Centre, says: “People 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 problems—from eye irritation and headaches to asthma and cancer.”

What Does the Data Actually Tell Us about the Risks Associated with Fracking?

Posted by Hadian 322 days ago in Miscellaneous from http://www.ucsusa.org

Technological advances such as horizontal drilling and hydraulic fracturing (commonly known as “fracking”) 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

More Than 500 Million People Might Face Increasing Water Scarcity

Posted by rdavtalab 323 days ago in Miscellaneous from http://www.sciencedaily.com

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 ...

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

Approximating SWAT Model Using Artificial Neural Network and Support Vector Machine

Posted by Kondwani 324 days ago in Planning and Management from http://onlinelibrary.wiley.com

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
