Rainwater could save people in India a bucket of money, according to a new study by scientists looking at NASA satellite data. The study, partially funded by NASA’s Precipitation Measurement Missions, found that collecting rainwater for vegetable irrigation could reduce water bills, increase caloric intake and even provide a second source of income for people in India.

What California can learn for Israel on solving serious water shortages
California is still counting up the damage from the 2014 drought, which resulted in more than $200 million in losses in the dairy and livestock industry and a staggering $810 million in crop production. And analysts are predicting this year to be even worse.
But many will admit that if there is any country on earth that knows how to trump a three-year (and counting) drought cycle and convert a wasteland to oasis, it’s Israel. For thousands of years, populations have been wresting a livelihood from the desert of what is now Israel, refining the techniques that would one day result in an agricultural paradise.
Beware the Giant Toxic Algae Bloom
Humans and animals on the west coast should take care when near the water. One of the largest algae blooms of all time is producing dangerous toxins which now stretch from California to Alaska. The neurotoxin being released by the bloom is called domoic acid, and it can cause a series of problems for any mammal that comes into contact with it.
Study examines overall carbon cost of fuel from Canadian oil sands
Gasoline and diesel fuel extracted and refined from Canadian oil sands will release about 20 percent more carbon into the atmosphere over the oil’s lifetime than fuel from conventional crude sources in the Unied States, according to a study by the U.S. Department of Energy’s Argonne National Laboratory; the University of California, Davis; and Stanford University.
The researchers used a life-cycle, or “well-to-wheels,” approach, gathering publicly available data on 27 large Canadian oil sands production facilities. The study, published in the journal Environmental Science and Technology, found the additional carbon impact of Canadian oil sands was largely related to the energy required for extraction and refining.
El Fracking ayuda a reducir la dependencia del carbón
Cuando usted activa un interruptor de la luz, lo más probable es que usted…está quemando carbón. Pero a medida que el auge del “fracking” sigue liberando enormes cantidades de gas natural, la red eléctrica del país está cambiando. Las centrales eléctricas están recurriendo cada vez más a este combustible fósil de bajo costo y más limpio al quemarse.
Bill PentaK se encuentra en medio de un sitio de construcción, echando un vistazo al último proyecto de su compañía que se eleva frente a él: una nueva central eléctrica de gas natural.
California's Isla Rasa being abandoned by seabirds
Isla Rasa, in the Gulf of California, is renowned for its massive aggregations of nesting seabirds. Over 95 percent of the world populations of Elegant Terns and Heerman's Gulls concentrate unfailingly every year on this tiny island to nest. Ever since the phenomenon was described by L. W. Walker in 1953 the island has been a magnet for tourists, naturalists, filmmakers, and seabird researchers.
During some years in the last two decades, however, the seabirds have arrived to the island in April, as they usually do, but leave soon after without nesting. The first event was the 1998 "El Niño," when oceanic productivity collapsed all along the eastern Pacific coast from Chile to California. But then colony desertion happened again in 2003, and since then it has recurred with increasing frequency in 2009, 2010, 2014, and 2015. Researchers and conservationists were asking themselves where are the birds going when they leave their ancestral nesting ground, and what is causing the abandonment of their historic nesting site.
