Washington Post: The 1991 eruption of Mount Pinatubo, a volcano in the Philippines, blasted enough fine particles and sulfur dioxide gas into the atmosphere to envelop the Earth in a high-altitude cloud for the better part of two months. When scientists checked in 1992, they determined that the cloud had deflected enough sunlight to cool the planet by about 1 degree. Now, with the planet warming inexorably and the threat of long-term climate change looming, some experts are wondering whether the time may have...

New Method Improves Solar Energy Efficiency, Cuts Costs
2013-09-07 20:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World News: Researchers have developed a method for improving the connections between stacked solar cells that allows for the greater overall efficiency of the solar energy devices. Developed by scientists from North Carolina State University, the new technique allows these cells to operate at solar concentrations of 70,000 suns worth of energy while minimizing the amount of voltage lost as "wasted energy," or heat. Stacked solar cells represent the most efficient cells on the market, converting up to...

Immense Pacific Volcano Among Solar System's Largest
2013-09-06 18:01:00| Climate Ark Climate Change & Global Warming Newsfeed
Yale Environment 360: A massive underwater volcano the size of New Mexico has been discovered 1,000 miles east of Japan, Nature Geoscience reports. Covering an area of 120,000 square miles, the volcano is 50 times larger than Hawaii's Mauna Loa, making it the largest volcano on Earth, according to a team of researchers from the U.S., Japan, and the U.K. The newly discovered volcano, named Tamu Massif, is only 25 percent smaller than the immense volcano on Mars, Olympus Mons, which is large enough to spot with a backyard...

5 Reasons Solar is Beating Fossil Fuels
2013-09-06 14:01:00| Climate Ark Climate Change & Global Warming Newsfeed
EcoWatch: The solar industry is growing drastically every year, while fossil fuels continue to be phased out. This is why it`s frustrating to hear people say that renewable energy is not ready to compete with fossil fuels as a means to power our country. Here are five reasons why solar is already winning. 1. Jobs There are more people in the U.S. employed in the solar energy marketplace than mining coal. The banal argument that transitioning to a clean energy economy will cost us jobs is simply false....
