Scientists endure Arctic for last campaign prior to CryoSat-2 launch
An international group of scientists has swapped their comfortable offices for one of the most inhospitable environments on the planet to carry out a challenging field campaign that is seen as the key to ensuring the data delivered by ESA's ice mission CryoSat will be as accurate as possible.

Federal polar bear research critically flawed, says study in INFORMS journal
Research done by the US Department of the Interior to determine if global warming threatens the polar bear population is so flawed that it cannot be used to justify listing the polar bear as an endangered species, according to a study being published later this year in Interfaces, a journal of the Institute for Operations Research and the Management Sciences.
The Interior Department has been ordered to make a determination by May 15.

NCAR installs 76-teraflop supercomputer for critical research on climate change, severe weather
Computer analyses of global climate have consistently overstated warming in Antarctica, new research concludes. The study can help scientists improve computer models and determine if Earth's southernmost continent will warm significantly this century, a major research question because of Antarctica's potential impact on global sea-level rise.

New gas sensors for monitoring carbon dioxide sinks
A novel gas sensor system makes it possible to monitor large areas cost-effectively the first time. The patented gas sensor is based on the principle of diffusion, according to which certain gases pass through a membrane faster than others. Using a tube-like sensor it is possible to measure an average gas concentration value over a certain distance without influencing or distorting conditions in the measuring environment.

Global climate models both agree and disagree with actual Antarctic data
Scientists who compared recorded Antarctic temperatures and snowfall accumulation to predictions by major computer models of global climate change offer both good and bad news. The models' predictions covering the last 50 years broadly follow the actual observed temperatures and snowfall for the southernmost continent, although the observations are very variable. That's the good news.

Rainfall and river networks prove accurate predictors of fish biodiversity
Princeton researchers have invented a method for turning simple data about rainfall and river networks into accurate assessments of fish biodiversity, allowing better prediction of the effects of climate change and the ecological impact of man-made structures like dams.

Amazon under threat from cleaner air
The Amazon rainforest, so crucial to the Earth's climate system, is coming under threat from cleaner air say prominent UK and Brazilian climate scientists in the leading scientific journal Nature.
The new study identifies a link between reducing sulphur dioxide emissions from burning coal and increasing sea surface temperatures in the tropical north Atlantic, resulting in a heightened risk of drought in the Amazon rainforest.

Biodiversity -- it's in the water
What if hydrology is more important for predicting biodiversity than biology?
Research published in the May 8 issue of the journal Nature challenges current thinking about biodiversity, and opens up new avenues for predicting how climate change or human activity may affect biodiversity patterns.

Chile's Chaiten volcano one of scores of active volcanoes in region, says CU-Boulder professor
The Chaiten volcano now erupting in southern Chile is one of 200 to 300 volcanoes in the "Andean Arc" region of Chile, Peru, Ecuador and Columbia considered active by volcanologists, some of which lie in much more densely populated areas, said a University of Colorado at Boulder geologist who has studied Chaiten.

Berkeley Lab researchers propose a new breed of supercomputers
Three researchers from the US Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have proposed an innovative way to improve global climate change redictions by using a supercomputer with low-power embedded microprocessors, an approach that would overcome limitations posed by today's conventional supercomputers.

Arable land can have a negative impact on air quality
Fallow agricultural land and steppe-formation processes are evidently capable of having a much greater effect on global air quality than was previously assumed. This is the conclusion drawn by researchers after examining a dust cloud that formed over parched fields in southern Ukraine and led to extremely high concentrations of particulate matter in Central Europe. On March 24, 2007, the dust cloud spread across Slovakia, Poland and the Czech Republic to Germany.

65-million-year-old asteroid impact triggered a global hail of carbon beads
The asteroid presumed to have wiped out the dinosaurs struck the Earth with such force that carbon deep in the Earth's crust liquefied, rocketed skyward, and formed tiny airborne beads that blanketed the planet, say scientists from the US, UK, Italy, and New Zealand in this month's Geology.
