Groundwater depletion and western US water supply
July 24, 2014 04:34 PM - NASA and UC Irvine

A new study by NASA and University of California, Irvine, scientists finds more than 75 percent of the water loss in the drought-stricken Colorado River Basin since late 2004 came from underground resources. The extent of groundwater loss may pose a greater threat to the water supply of the western United States than previously thought. This study is the first to quantify the amount that groundwater contributes to the water needs of western states. According to the U.S. Bureau of Reclamation, the federal water management agency, the basin has been suffering from prolonged, severe drought since 2000 and has experienced the driest 14-year period in the last hundred years.

Soccer Under The Sun
June 20, 2014 08:00 AM - Winfield Winter, ENN

The 2014 FIFA World Cup Brazil is underway and off to a bright start. For the first time in the tournament's history, matches will be held in stadiums powered by solar energy. Footballers from the 32 nations represented may curse the sun and the swelter it brings, but Yingli Solar, the world's largest solar panel manufacturer and a FIFA World Cup Sponsor, has captured an opportunity on the world's biggest stage. Yingli Solar estimates its solar panels to generate more than 1MW per year and clean electricity for 25 years or more. The iconic Estádio do Maracanã that witnessed Pelé's 1000th career goal and much of Brazil's rich footballing history is one of the two sites that received this modern upgrade. This Rio de Janeiro landmark that opened in 1950 now boasts 1,500 Yingli Solar panels with the capability to produce 550MWh of clean electricity per year.

Climate Change Decadal Pause Study — Accidental Climate Mitigation

Professor Jesse Thé and Professor Roydon Fraser, University of Waterloo
Professors Jesse Thé and Roydon Fraser from the University of Waterloo are initiating a study on the potential cause of the decade long pause on global warming. This is an interview with Prof. Thé, as a disclosure is also ENN’s Editor-in-Chief. . ENN: What is causing this decade long pause on the average global temperature increase? Prof. Thé: First of all, note that the last decade was the warmest on record. While the maximum temperatures are not increasing as fast, we are not seen a real pause on temperature increase, just a significant reduction on its growth rate. Second, researchers are not certain and our work at this stage can only be placed in the scientific method as a hypothesis. Until we develop the full analysis, all my views in this interview are based on our hypothesis that the pause in the temperature increase is cause by the aerosol formation form the massive burning of coal in China (50% of global consumption of coal) and India.

Dandelion Salad, Anyone?

July 22nd, 2014
Yes, dandelion salad is a real thing, not just a made up salad that kids make while playing pretend in the back yard. In fact, many commonly found plants are actually edible, including dandelions. I thought it would be fun to include some easily found leafy appetizers for ENN users to experiment with. Of course, not all plants are edible, so it is important to correctly identify a plant before trying to eat it.

Are You Smarter Than A Trash Can?

July 12th, 2014
Walking through Boston earlier this week I came across an unusually large trash receptacle. When I went closer to inspect it (throw out my trash) I noticed that it was compactor designed for sustainability.  Besides having a function to compact the trash which would require less pickups, the cans also had solar panels to be [...]
