Scientists Suggest Water Vapor Will Intensify Future Climate Change Projections
2014-07-30 03:07:27

University of Miami Rosenstiel School of Marine & Atmospheric Science A new study from scientists at the University of Miami Rosenstiel School of Marine and Atmospheric Science and colleagues confirms rising levels of water vapor in the upper troposphere – a key amplifier of global warming – will intensify climate change impacts over the next decades. The new study is the first to show that increased water vapor concentrations in the atmosphere are a direct result of human...

NASA To Search For Climate Change Clues In The Tropopause

[ Watch the Video: Global Hawk Gets To Work In The Western Pacific ] redOrbit Staff & Wire Reports - Your Universe Online NASA has deployed their pilot-less Global Hawk research aircraft in the western Pacific in order to monitor changes to the upper atmosphere and discover how changes there are impacting the planet’s climate. The mission, announced by the US space agency on Friday, is part of their Airborne Tropical Tropopause Experiment (ATTREX) airborne science campaign....

WASHINGTON, Jan. 17, 2014 /PRNewswire-USNewswire/ -- NASA's uncrewed Global Hawk research aircraft is in the western Pacific region on a mission to track changes in the upper atmosphere and help researchers understand how these changes affect Earth's climate. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) Deployed from NASA's Dryden Flight Research Center in Edwards, Calif., the Global Hawk landed at Andersen Air Force Base in Guam Thursday at approximately 5 p.m....

Climate Change Clues Could Come From The Stratosphere

redOrbit Staff & Wire Reports - Your Universe Online NASA has announced plans to send an unmanned, remotely-controlled research vehicle into the upper atmosphere in order to find out what impact climate change is having on our planet. The program, which has been christened the Airborne Tropical Tropopause Experiment (ATTREX), will utilize instruments on board a long-range Global Hawk aircraft to collect measurements above the tropical Pacific Ocean, the US space agency explained....

Thousands Of Microorganisms Make Their Way To West Coast Riding Plumes Across The Pacific
2012-12-18 10:48:12

University of Washington A surprising number of microorganisms — 99 percent more kinds than had been reported in findings published just four months ago — are leaping the biggest gap on the planet. Hitching rides in the upper troposphere, they´re making their way from Asia across the Pacific Ocean and landing in North America. For the first time researchers have been able to gather enough biomass in the form of DNA to apply molecular methods to samples from two large...

Deep Ocean Currents Affected By Atmosphere

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...

U.S. and British meteorologists said on Monday that not only is Earth's surface warming, but the troposphere is heating up also. The scientists found that warming in this key atmospheric layer was occurring, just as many researchers expected as more greenhouse gases build up and trap heat close to the Earth. This study put to rest a controversy that began 20 years ago when a 1990 scientific report raised questions about whether the troposphere was warming, even as Earth's surface...

Spanish researchers have measured CO2 levels for the past three years in the troposphere (lower atmosphere) over a sparsely inhabited rural area near Valladolid. The results, which are the first of their kind in the Iberian Peninsula, show that the levels rose "significantly" between 2002 and 2005. Over recent years, physicists and meteorologists have been trying to find out about carbon dioxide (CO2) levels, and how these have evolved in the troposphere over various urban and rural areas...

U.S. and Swiss scientists say unusual atmospheric circulation might have caused the 1930s Dust Bowl and could also be responsible for other droughts. The researchers from the Institute for Atmospheric and Climate Science in Zurich, Switzerland; the Observatory and World Radiation Center in Davos, Switzerland, and the U.S. National Climatic Data Center in Asheville, N.C., said they used historical upper air data, reconstructions and model simulations to analyze atmospheric circulation during...


Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
