By tailoring geoengineering efforts by region and by need, a new model promises to maximize the effectiveness of solar radiation management while mitigating its potential side effects and risks. The study explores the feasibility of using solar geoengineering to counter the loss of Arctic sea ice.
A research team from the University of California, Santa Barbara and Portland State University has retrieved a sensor containing previously unavailable data about changes in chemistry or acidification in the remote waters of McMurdo Sound in Antarctica. The device collected data through June, when the battery expired in the harsh polar sea.
Increasing demand for bioenergy feedstock is generating land-use conflicts and food vs. fuel controversies. An team of 11 scientists from seven European countries and the United States have recently published a study that gives scientific background to the debate. It supports a reassessment of the land available for bioenergy feedstock production.
Overturning decades of conventional wisdom, researchers at Lawrence Berkeley National Laboratory have found that moderately high indoor concentrations of carbon dioxide can significantly impair people's decision-making performance. The results were unexpected and may have particular implications for schools and other spaces with high occupant density.
A U.K. research team has recently determined that the geometry of channels beneath the ice can be a strong control on ice behaviour, temporarily hiding the signals of retreat. The findings, which provide the first simulation of past ice-sheet retreat and collapse over a ten thousand year period in Antarctica, shed new light on what makes ice stable or unstable and will help refine predictions of future ice extent and global sea-level rise, the researchers say.
Atmospheric chemists at Harvard University have found that when it comes to secondary organic material (SOM) in the atmosphere, there are two distinct breeds: liquids and jellies. Their experiments, using particle of a-pinene SOM and adipic acid, have shown that a drop in humidity can send these common aerosols into a jelly-like phase, in which they resist chemical aging almost entirely.
Crude oil extraction could be improved significantly and accessible domestic oil reserves could be expanded with an economical carbon dioxide thickener being developed by University of Pittsburgh engineers, thanks to a $1.3 million grant from the U.S. Department of Energy.
For the first time, three separately found extreme Earth events have been compared by researchers who now believe they may be linked. About 41,000 years ago, a complete and rapid reversal of the geomagnetic field occurred, lasting for just a few hundred years. Around the same time, a super volcano erupted and major climate changes occurred.
Science is full of surprises. College of Wooster chemist Paul Edminston's search for a new way to detect explosives at airports instead led to the creation of what's now called "Osorb," swellable, organically modified silica, or glass, capable of absorbing oil and other contaminants from water.
To combat the effects of climate change, some scientists have proposed temporarily reducing the amount of sunlight reaching the earth. These various geoengineering schemes have typically thought as a standalone fix, but a new computer analysis of future climate change considers emissions reductions together with sunlight reduction. The model shows that such drastic steps to cool the earth would only be necessary in certain scenarios.
While the North Pole has been losing sea ice over the years, the water nearest the South Pole has been gaining it. Antarctic sea ice hit a record 7.51 million square miles in September, just days after reports of the biggest loss of Arctic sea ice on record. Climate change skeptics have seized on this example, but scientists say the skeptics are misinterpreting what's happening and why.
The natural decay of organic carbon contributes more than 90% of the yearly carbon dioxide released into Earth's atmosphere and oceans. Understanding the rate at which leaves decay can help scientists predict this global flux of carbon dioxide. But a single leaf may undergo different rates of decay depending on a number of variables. Researchers have just built a mathematical model that incorporates these variables, and have discovered a commonality within the diversity of leaf decay.
Applying a global energy-economy computer simulation that fully captures the competition between alternative power supply technologies, a team of scientists from the Potsdam Institute for Climate Impact Research and the University of Dayton, Ohio, analyzed trade-offs between nuclear and climate policies. They found that incremental costs due to policy options restricting the use of nuclear power do not significantly increase the cost of even stringent greenhouse-gas emissions reductions.
Water does not forget, says Prof. Boris Koch, a chemist at the Alfred Wegener Institute for Polar and Marine Research. With the combination of some new techniques, Koch and colleagues can now identify and retrace some of the biomolecular tracks left by living organism. This dissolved organic matter, detectable with mass spectrometry, is one of the largest active, organic carbon reservoirs on earth.
The global engineering and construction company M+W Group strengthens its capabilities in the automation business. Today the company announced that M+W Automation, a subsidiary of their operations in the Americas, purchased 100 percent of Spectrum Engineering Solutions (Spectrum Engineering...
Our greenhouse gas emissions up to now have triggered an irreversible warming of the Earth that will cause sea levels to rise for thousands of years to come, new research has show. The results come from a study which sought to model sea-level changes over millennial timescales, taking into account all of the Earth's land ice and the warming of the oceans.
A Horizon Lines container ship outfitted with meteorological and atmospheric instruments installed by scientists from Argonne National Laboratory and Brookhaven National Laboratory will begin taking data for a yearlong mission aimed at improving the representation of clouds in climate models.

According to research done at the Harvard Forest Long-Term Ecological Research site in Masschusetts, autumn colors were different there a century, or even a half-century, ago. And they will likely continue to change as alterations to the landscape occur through changing climate, tree disease, and harvesting practices.
NASA’s Hurricane and Severe Storm Sentinel (HS3) investigation is a five-year mission to better understand the processes that underlie hurricane intensity change in the Atlantic Ocean basin. The Global Hawk is a key part of that effort, and its flights into the hurricane’s environment allow several highly-advanced, autonomously operated instruments to gauge everything from wind speed to cloud structures.

According to recent paper published by Yale University scientists, an international policy is needed for recycling scarce specialty metals that are critical in the production of consumer goods. Specialty metals account for more than 30 of the 60 metals on the periodic table, and their rapidly accelerating usage in many industries makes the complete lack of recycling a concern.
