Where did Venus's water go?
Venus Express has made the first detection of an atmospheric loss process on Venus's day-side. Last year, the spacecraft revealed that most of the lost atmosphere escapes from the night-side.   view more (2008-12-19)

No quick or easy technological fix for climate change, researchers say
Global warming, some have argued, can be reversed with a large-scale "geoengineering" fix, such as having a giant blimp spray liquefied sulfur dioxide in the stratosphere or building tens of millions of chemical filter systems in the atmosphere to filter out carbon dioxide.    view more (2008-12-18)

Post-pandemic reforestation in New World helped trigger Little Ice Age, Stanford researchers say
The power of viruses is well documented in human history. Swarms of little viral Davids have repeatedly laid low the great Goliaths of human civilization, most famously in the devastating pandemics that swept the New World during European conquest and settlement.    view more (2008-12-18)

ESA tests laser to measure atmospheric carbon dioxide
A recent ESA campaign has demonstrated how a technique using lasers could be employed to measure carbon dioxide in the atmosphere. The campaign supports one of the main objectives of the candidate Earth Explorer A-SCOPE mission.   view more (2008-12-04)

Foretelling a major meltdown
By discovering the meaning of a rare mineral that can be used to track ancient climates, Binghamton University geologist Tim Lowenstein is helping climatologists and others better understand what we're probably in for over the next century or two as global warming begins to crank up the heat - and,... view more (2008-12-02)

Ocean growing more acidic faster than once thought
University of Chicago scientists have documented that the ocean is growing more acidic faster than previously thought. In addition, they have found that the increasing acidity correlates with increasing levels of atmospheric carbon dioxide.   view more (2008-11-25)

Carbon dioxide already in danger zone, warns study
A group of 10 prominent scientists says that the level of globe-warming carbon dioxide in the air has probably already reached a point where world climate will change disastrously unless the level can be reduced in coming decades.   view more (2008-11-19)

Water vapor confirmed as major player in climate change
Water vapor is known to be Earth's most abundant greenhouse gas, but the extent of its contribution to global warming has been debated.   view more (2008-11-18)

Revised theory suggests carbon dioxide levels already in danger zone
If climate disasters are to be averted, atmospheric carbon dioxide (CO2) must be reduced below the levels that already exist today, according to a study published in Open Atmospheric Science Journal by a group of 10 scientists from the United States, the United Kingdom and France.    view more (2008-11-10)

It's relative: Contrasting hurricane theories heat up
In a paper published in the journal Science today, scientists Gabriel A. Vecchi of NOAA's Geophysical Fluid Dynamics Laboratory, Kyle L. Swanson of the University of Wisconsin - Milwaukee Atmospheric Sciences Group and Brian J. Soden from the University of Miami's Rosenstiel School of Marine and... view more (2008-11-03)

Methane gas levels begin to increase again
The amount of methane in Earth's atmosphere shot up in 2007, bringing to an end a period of about a decade in which atmospheric levels of the potent greenhouse gas were essentially stable, according to a team led by MIT researchers.   view more (2008-10-30)

Potent greenhouse gas more prevalent in atmosphere than previously assumed
A powerful greenhouse gas is at least four times more prevalent in the atmosphere than previously estimated, according to a team of researchers at Scripps Institution of Oceanography at UC San Diego.   view more (2008-10-24)

MU Scientist Uses Tracer to Predict Ancient Ocean Circulation
Even though the Cretaceous Period ended more than 65 million years ago, clues remain about how the ocean water circulated at that time.   view more (2008-10-21)

When it comes to forest soil, wildfires pack 1-2 punch
For decades, scientists and resource managers have known that wildfires affect forest soils, evidenced, in part, by the erosion that often occurs after a fire kills vegetation and disrupts soil structure.   view more (2008-10-17)

2008 ozone hole larger than last year
The 2008 ozone hole - a thinning in the ozone layer over Antarctica - is larger both in size and ozone loss than 2007 but is not as large as 2006.   view more (2008-10-08)

Brookhaven Scientists Take Off for Southeastern Pacific Climate Study
During October and November 2008, some 150 scientists from 40 institutions in eight nations - including scientists from the U.S. Department of Energy's (DOE) Brookhaven National Laboratory - will take part in an international field experiment designed to make observations of critical components of... view more (2008-10-07)

NASA study finds rising Arctic storm activity sways sea ice, climate
A new NASA study shows that the rising frequency and intensity of arctic storms over the last half century, attributed to progressively warmer waters, directly provoked acceleration of the rate of arctic sea ice drift, long considered by scientists as a bellwether of climate change.   view more (2008-10-07)

Cassini flyby of Saturn moon offers insight into solar system history
NASA's Cassini spacecraft is scheduled to fly within 16 miles of Saturn's moon Enceladus on Oct. 9 and measure molecules in its space environment that could give insight into the history of the solar system.   view more (2008-10-07)

Next-generation adaptive optics produces sharper Jupiter images
A two-hour observation of Jupiter using an improved technique to remove atmospheric blur has produced the sharpest whole-planet picture ever taken from the ground, according to astronomers from the University of California, Berkeley, and the European Southern Observatory (ESO).   view more (2008-10-03)

Case Western Reserve University researchers track Chernobyl fallout
When a reactor in the Chernobyl nuclear power plant exploded in 1986 in what was then the Soviet republic of Ukraine, radioactive elements were released in the air and dispersed over the Soviet Union, Europe and even eastern portions of North America.   view more (2008-10-02)

Emissions rising faster this decade than last
The latest figures on the global carbon budget to be released in Washington and Paris today indicate a four-fold increase in growth rate of human-generated carbon dioxide emissions since 2000.   view more (2008-10-02)

CU-Boulder space scientists set for second spacecraft flyby of Mercury
NASA's MESSENGER spacecraft, which is toting an $8.7 million University of Colorado at Boulder instrument to measure Mercury's wispy atmosphere and blistering surface, will make its second flyby of the mysterious, rocky planet Oct. 6.   view more (2008-10-01)

Method of predicting clear air turbulence could make flights smoother in the future
It comes blasting out of the blue on your airplane flight: sudden bumpiness and sometimes even a violent plummeting. It arrives without warning, and it can be more than frightening, since it causes tens of millions of dollars in injury claims every year.   view more (2008-10-01)

Water table depth tied to droughts
Will there be another "dust bowl" in the Great Plains similar to the one that swept the region in the 1930s?   view more (2008-09-30)

Growth in the global carbon budget
Today the new Global Carbon Budget was launched simultaneously by Global Carbon Project co-chair Michael Raupach in France at the Paris Observatory, and in the USA at Capitol Hill, Washington by GCP Executive Director Pep Canadell.   view more (2008-09-25)
