DeWayne Cecil, PhD, Reports on Human Health Effects of Global Warming for Founder of Bio Logic Aqua Research, Sharon Kleyne Grants Pass, OR (PRWEB) November 15, 2013 Changes in atmospheric water content, as a result of warming temperatures and changing climate and precipitation patterns, have significant potential and observed impacts on water-borne disease outbreaks and human health. That was one of the conclusions in a recent White Paper by Climatologist DeWayne Cecil, PhD, for a study...

Young Sun Paradox Early Climate
2013-10-04 13:46:54

Brett Smith for redOrbit.com - Your Universe Online When life originated on Earth between 3.8 and 2.4 billion years ago during the Archean era, our sun was only functioning at about 75 percent of its current power. With this ‘low wattage’ sun, the Earth should have been covered in glaciers, yet scientists have found no evidence of this taking place. In a new study published recently by the journal Science, a team of international researchers’ analysis of rock samples dating back...

Study Finds Human Activity Affects Vertical Structure Of Atmospheric Temperature
2013-09-17 13:05:39

Lawrence Livermore National Laboratory Human influences have directly impacted the latitude/altitude pattern of atmospheric temperature. That is the conclusion of a new report by scientists from Lawrence Livermore National Laboratory and six other scientific institutions. The research compares multiple satellite records of atmospheric temperature change with results from a large, multi-model archive of simulations. "Human activity has very different effects on the temperature of the...

Cassini Uncovers New Data About Saturn's Atmosphere Composition
2013-09-04 11:00:03

[ Watch the Video: Saturn Storm Reveals Its Explosive Power ] Lee Rannals for redOrbit.com - Your Universe Online A new analysis of near-infrared images taken by NASA's Cassini orbiter is providing more data about the composition of Saturn's atmosphere. Scientists, publishing a paper in the journal Icarus, say they have discovered that cloud particles at the top of Saturn's great storms are composed of a mix of three substances, including water ice, ammonia ice and an uncertain third...

Tracking Russian Meteor Debris Field Offers Insight Into Future Events
2013-08-15 14:38:54

[WATCH VIDEO: Meteor Debris Around The World In Four Days] Brett Smith for redOrbit.com - Your Universe Online Using satellite data and computer models, NASA scientists were able to track and study the debris of the meteor that exploded over Chelyabinsk, Russia in February, giving them a better picture of how similar future events might affect the Earth’s atmosphere. Just after sunrise on February 15, a meteor measuring about 59 feet across and weighing over 12,000 tons exploded...

Venus Express Observes Strenghtening Winds On Second Planet From Sun
2013-06-18 15:11:30

Lee Rannals for redOrbit.com — Your Universe Online The European Space Agency's (ESA) Venus Express spacecraft has revealed that the winds on the second planet from the Sun have been getting faster over the last six years. Venus holds a super-rotating atmosphere that is able to whip around the planet once every four Earth days. Scientists are able to monitor patterns in the long-term global wind speeds by tracking the movements of distinct features in the clouds of the planet....

NASA AIM Satellite Spots First Noctilucent Clouds Of 2013
2013-06-09 09:08:50

redOrbit Staff & Wire Reports — Your Universe Online Noctilucent clouds (NLCs), tenuous cloud-like phenomena that form every summer in the skies above the North Pole, are forming earlier than usual, NASA officials confirmed on Friday. According to the US space agency, NLCs are formed when “ice crystals begin to cling to the smoky remains of meteors, forming electric-blue clouds with tendrils that ripple hypnotically against the sunset sky.” These clouds, which...

Pollution, Storms And Climate: NASA Mission Investigates How They Interact
2013-06-07 11:09:55

April Flowers for redOrbit.com - Your Universe Online To investigate how air pollution and natural emissions, which are pushed high into the atmosphere by large storms, affect atmospheric composition and climate, NASA´s DC-8 and ER-2 science aircraft will take flight over the southern US this summer. This will be the most complex NASA airborne science campaign of the year drawing together coordinated observations from NASA satellites, aircraft and an array of ground sites. The...

NASA Curiosity Finds Evidence Of Atmosphere Thinning On Mars
2013-04-08 11:54:31

Lawrence LeBlond for redOrbit.com - Your Universe Online NASA´s Curiosity rover has been busy searching for signs that life may have once existed on the Red Planet. In the eight months since NASA dropped the rover on Mars, it has made significant progress in the hunt for water and life. In the latest round of evidence pertaining to Mars´ past, new measurements from Curiosity point towards the sky. These measurements, which consisted of analysis of Argon atoms in the...

Earth's Atmosphere
2004-10-19 04:45:44

Earth's Atmosphere -- Earth's atmosphere consists of nitrogen (78.1%) and oxygen (20.9%), with small amounts of argon (0.9%), carbon dioxide (variable, but around 0.035%), water vapor, and other gases. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation and reducing temperature extremes between day and night. 75% of the atmosphere exists within 11km of the planetary surface. Temperature and the Atmospheric Layers The temperature of the Earth's atmosphere...

Sky
2004-10-19 04:45:44

Sky -- Although almost everyone have seen it, sky is hard to be defined precisely. Generally, sky is the space seen when one looks upward from the surface of a planet. Some people define sky as the denser gaseous zone of a planet's atmosphere. Clouds, rainbows and weather all occur amongst a planet's sky. In astronomy, the sky is divided into many regions, called constellations. The blue colour of the daytime sky results from the selective scattering of light rays. When the sunlight...

Saturn's Moon Titan
2004-10-19 04:45:41

Saturn's moon Titan -- Titan is the planet Saturn's largest moon. It is larger than either of the planets Mercury or Pluto and is the second-largest moon in the solar system after Ganymede (it was originally thought to be slightly larger than Ganymede, but recent observations have shown that its thick atmosphere caused overestimation of its diameter). Titan was discovered on March 25, 1655 by the Dutch astronomer Christian Huygens, making it one of the first non-terrestrial moons to be...
