ENERTIA® CEO Michael Sykes announces three new Extreme EX models of the Award-Winning Green kit-home series, with beefed up thermal mass for more inertia, and reflective hidden internal surfaces like a thermos bottle. Because they are connected to the earth, and face the sun, Enertia homes can maintain livable conditions when there is no electricity, or fuel supply. Youngsville, NC (PRWEB) March 25, 2014 Few homes are ready for the next Polar Vortex, with power outages and shortages...

Changing Seasons On Titan
2013-04-12 07:40:24

April Flowers for redOrbit.com - Your Universe Online The latest sign that the change of seasons has started a cascade of radical changes in the atmosphere on Titan is an ice cloud taking shape over the south pole. This type of cloud, made from unknown ice, has long hung over the north pole. According to observations by the composite infrared spectrometer (CIRS) on NASA's Cassini spacecraft, the northern cloud is now fading. "We associate this particular kind of ice cloud with winter...

Causes Of 2011 Arctic Ozone Hole Pinpointed By NASA
2013-03-12 10:16:04

NASA A combination of extreme cold temperatures, man-made chemicals and a stagnant atmosphere were behind what became known as the Arctic ozone hole of 2011, a new NASA study finds. Even when both poles of the planet undergo ozone losses during the winter, the Arctic´s ozone depletion tends to be milder and shorter-lived than the Antarctic´s. This is because the three key ingredients needed for ozone-destroying chemical reactions –chlorine from man-made...

Deep Ocean Currents Affected By Atmosphere
2012-09-24 11:23:52

Brett Smith for redOrbit.com - Your Universe Online Atmospheric researchers at the University of Utah have uncovered a Rube Goldberg-like mechanism that begins in the polar stratosphere and drives global weather patterns through a chain of interactions, according to a new report. "It is not new that the stratosphere impacts the troposphere," said University of Utah professor Thomas Reichler, senior author of the report published in the journal Nature Geoscience. "It also is not new...

Arctic Ice Melt Setting The Stage For Severe Winters
2012-06-07 04:09:38

The dramatic melt-off of Arctic sea ice due to climate change is hitting closer to home than millions of Americans might think. That's because melting Arctic sea ice can trigger a domino effect leading to increased odds of severe winter weather outbreaks in the Northern Hemisphere's middle latitudes — think the "Snowmageddon" storm that hamstrung Washington, D.C., during February 2010. Cornell's Charles H. Greene, professor of earth and atmospheric sciences, and Bruce C. Monger,...

Unusually Chilly Stratosphere Behind 2011′s Record Arctic Ozone Hole
2011-10-20 08:06:37

Check the fine print on many cans of hairspray or shaving cream these days, and you´ll probably find a reassurance that the product you are holding contains “No CFCs or chemicals known to harm the ozone layer.” Located in the stratosphere, the ozone layer protects life on Earth from the harmful effects of ultraviolet radiation. To stop ozone destruction, chemical manufacturers phased out the production of CFCs (short for chlorofluorocarbons) over the past two decades. So...

CFC's the Real Reason for Ozone Loss?
2011-10-13 03:04:52

Op/ed By Kevin Roeten (roetenks@charter.net) How many individuals and corporations have lost money and jobs over theoretical ozone depletion? Why have natural variations never been considered as a possible reason for seasonal ozone loss? With ozone (O3) depletion, millions were (and are) convinced that chlorofluorocarbons (CFC´s), and certain brominated compounds (Halons), were responsible. Due to their theorized Ozone Depletion Potential (ODS), the most stable non-toxic refrigerants,...

Scientists Detect First-Ever Arctic Ozone Hole
2011-10-03 05:19:46

A team of international researchers, led by NASA scientists, has discovered an unprecedented loss of protective ozone in the atmosphere above the Arctic this year, according to various media reports published on Sunday. That phenomenon, according to an AFP article, has led to the formation of an ozone hole five times the size of the state of California. It marks the first time that ozone loss in the Arctic region has matched ozone loss above Antarctica, both they and Postmedia News are...
