Earth's early ocean cooled more than a billion years earlier than thought: Stanford study
The scalding-hot sea that supposedly covered the early Earth may in fact never have existed, according to a new study by Stanford University researchers who analyzed isotope ratios in 3.4 billion-year-old ocean floor rocks. view more (2009-11-12)
Antarctica glacier retreat creates new carbon dioxide store
Large blooms of tiny marine plants called phytoplankton are flourishing in areas of open water left exposed by the recent and rapid melting of ice shelves and glaciers around the Antarctic Peninsula. view more (2009-11-10)
Texas A&M prof to predict weather on Mars
Is there such a thing as "weather" on Mars? There are some doubts, considering the planet's atmosphere is only 1 percent as dense as that of the Earth. view more (2009-11-05)
Carbon atmosphere discovered on neutron star
Evidence for a thin veil of carbon has been found on the neutron star in the Cassiopeia A supernova remnant. This discovery, made with NASA's Chandra X-ray Observatory, resolves a ten-year mystery surrounding this object. view more (2009-11-05)
NRL sensor provides critical space weather observations
Launched from Vandenberg Air Force Base, Calif., aboard an United Launch Alliance Atlas V launch vehicle, Oct. 18, 2009, the Special Sensor Ultraviolet Limb Imager (SSULI) developed by NRL's Space Science Division and Spacecraft Engineering Department offers a first of its kind technique for remote sensing of the ionosphere and thermosphere from... view more...

'Ultra-primitive' particles found in comet dust
Dust samples collected by high-flying aircraft in the upper atmosphere have yielded an unexpectedly rich trove of relicts from the ancient cosmos, report scientists from the Carnegie Institution. view more (2009-11-03)
Volcanoes played pivotal role in ancient ice age, mass extinction
Researchers here have discovered the pivotal role that volcanoes played in a deadly ice age 450 million years ago. Perhaps ironically, these volcanoes first caused global warming -- by releasing massive amounts of carbon dioxide into the atmosphere. When they stopped erupting, Earth's climate was thrown off balance, and the ice age began. view more (2009-10-27)
Arctic land and seas account for up to 25 percent of world's carbon sink
In a new study in the journal Ecological Monographs, ecologists estimate that Arctic lands and oceans are responsible for up to 25 percent of the global net sink of atmospheric carbon dioxide. view more (2009-10-15)
Tropical Storm Nepartak becoming extra-tropical at sea
Tropical Storm Nepartak is now speeding in a northeasterly direction in the northwestern Pacific Ocean, where it is becoming extra-tropical and developing frontal qualities. view more (2009-10-14)
Do dust particles curb climate change?
A knowledge gap exists in the area of climate research: for decades, scientists have been asking themselves whether, and to what extent man-made aerosols, that is, dust particles suspended in the atmosphere, enlarge the cloud cover and thus curb climate warming. view more (2009-10-07)
Simulation suggests rocky exoplanet has bizarre atmosphere
So accustomed are we to the sunshine, rain, fog and snow of our home planet that we find it next to impossible to imagine a different atmosphere and other forms of precipitation. view more (2009-10-01)
Lunar Reconnaissance Orbiter's LAMP shedding light on permanently shadowed regions of the Moon
NASA's Lunar Reconnaissance Orbiter (LRO), launched on June 18 of this year, has begun its extensive exploration of the lunar environment and will return more data about the Moon than any previous mission. view more (2009-09-18)
University of Toronto study shows climate change will lead to less ultraviolet radiation over northern high latitudes
Physicists at the University of Toronto have discovered that changes in the Earth's ozone layer due to climate change will reduce the amount of ultraviolet (UV) radiation in northern high latitude regions such as Siberia, Scandinavia and northern Canada. view more (2009-09-16)
University of Hawai'i at Manoa team unravels the chemistry of Titan's hazy atmosphere
A team of University of Hawai'i at Mānoa researchers led by Ralf Kaiser, physical chemist at UH Mānoa, unraveled the chemical evolution of the orange-brownish colored atmosphere of Saturn's moon Titan, the only solar system body besides Venus and Earth with a solid surface and thick atmosphere. view more (2009-09-15)
New CO2 data helps unlock the secrets of Antarctic formation
The link between declining CO2 levels in the earth's atmosphere and the formation of the Antarctic ice caps some 34 million years ago has been confirmed for the first time in a major research study. view more (2009-09-14)
Ancient oceans offer new insight into the origins of animal life
Analysis of a rock type found only in the world's oldest oceans has shed new light on how large animals first got a foothold on the Earth. view more (2009-09-10)
Scientists say climate change mitigation strategies ignore carbon cycling processes of inland waters
In the paper, The Boundless Carbon Cycle, published in the September issue of Nature Geoscience, scientists from the University of Vienna, Uppsala University in Sweden, University of Antwerp, and the U.S. based Stroud™ Water Research Center argue that current international strategies to mitigate manmade carbon emissions and address climate... view more...

NOAA study shows nitrous oxide now top ozone-depleting emission
Nitrous oxide has now become the largest ozone-depleting substance emitted through human activities, and is expected to remain the largest throughout the 21st century, NOAA scientists say in a new study. view more (2009-08-28)
Water in a changing climate
New research announced at the international Water in a changing climate science conference in Melbourne 24-28 August, implicates pollution from Asia, Europe and North America as a contributor to recent Australian rainfall changes. view more (2009-08-27)
The greenhouse gas that saved the world
When Planet Earth was just cooling down from its fiery creation, the sun was faint and young. So faint that it should not have been able to keep the oceans of earth from freezing. But fortunately for the creation of life, water was kept liquid on our young planet. view more (2009-08-18)
