Landsat Satellites Track Yellowstone's Geothermal Activity

Yellowstone National Park sits on top of a vast, ancient, and still active volcano. Heat pours off its underground magma chamber, and is the fuel for Yellowstone's famous features -- more than 10,000 hot springs, mud pots, terraces and geysers, including Old Faithful.But expected development by energy companies right outside Yellowstone's borders have some fearing that Old Faithful could be cheated out of its energy.

The park funded a study by Lawrence and his co-author Shannon Savage to apply a new perspective to the problem of tracking geothermal activity. Their work is being presented at the American Geophysical Union conference in San Francisco on December 9. Lawrence and Savage used both visible light and heat-sensitive Landsat data channels to get a broad view of the park's geothermal activity....

Whales win, walruses lose in warmer Arctic

The Arctic zone has moved into a warmer, greener "new normal" phase, which means less habitat for polar bears and more access for development, an international scientific team reported.Arctic air temperatures were higher - about 2.5 degrees F (1.5 degrees C) higher in 2011 than the baseline number for the previous 30 years - and there was a dramatic loss of sea ice and glacier mass, the scientists said in a telephone briefing.

London Bridge Will Soon Be All Lit Up With LEDs!

It was over 25 years ago that the London Bridge lighting system, used to illuminate the landmark at night, was last upgraded. But GE and its UK partner EDF Energy recently received a formal approval to retrofit the 800-foot bridge with new energy efficient LED technology and a cabling system that will bring it into the 21st century with style.

Galaxies learned to "go green" early in the history of the universe

Galaxies learned to "go green" early in the history of the universe, continuously recycling immense volumes of hydrogen gas and heavy elements to build successive generations of stars stretching over billions of years.This ongoing recycling keeps galaxies from emptying their "fuel tanks" and therefore stretches out their star-forming epoch to over 10 billion years. However, galaxies that ignite a rapid firestorm of star birth can blow away their remaining fuel, essentially turning off further star-birth activity....
