This is a extra special year for "Super Moons"
July 12, 2014 06:55 AM - Roger Greenway, ENN

Super Moons are full moons that are extra, well, super! They are super because they appear larger in the evening sky than your run of the mill full moon. In June of last year, a full Moon made headlines. The news media called it a "supermoon" because it was 14% bigger and 30% brighter than other full Moons of 2013. Around the world, people went outside to marvel at its luminosity. If you thought one supermoon was bright, how about three? The full Moons of summer 2014—July 12th, August 10th, and Sept. 9th--will all be supermoons. The scientific term for the phenomenon is "perigee moon." Full Moons vary in size because of the oval shape of the Moon's orbit. The Moon follows an elliptical path around Earth with one side ("perigee") about 50,000 km closer than the other ("apogee"). Full Moons that occur on the perigee side of the Moon's orbit seem extra big and bright.

Record Radiation in South America
July 11, 2014 09:00 AM - Winfield Winter, ENN

Astrobiologists from the United States and Germany recorded the highest known level of solar UV radiation to reach Earth's surface. This was around 10 years ago. On December 29, 2003, the UV Index (UVI) peaked, reaching the blistering number of 43.3 over the Andes Mountains in Bolivia. To put this in context, a beachgoer in the United States would expect a UVI of 8 or 9 on a summer day. Even with an 8 or a 9, one may not escape the day without sunburn. Nonetheless, it has taken scientists 10 years to detail a report of this data while taking into account all of the variables and anomalies monitored from an international network of dosimeters — or Eldonets (European Light Dosimeter Network) — that measure UV radiation worldwide. This system is comprised of more than 100 stations across 5 continents to account for variation in the atmosphere above each station.

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.
