ScienceDaily (Sep. 11, 2008) — Microbes that break down oil and petroleum are more diverse than we thought, suggesting hydrocarbons were used as an energy source early in Earth’s history, scientists heard at the Society for General Microbiology’s Autumn meeting being held this week at Trinity College, Dublin. These microbes can change the composition of [...]

San Francisco, CA — A coalition of conservation groups is taking the Bush administration to court because of weak management plans that threaten wildlife in 10 Sierra Nevada national forests.
The groups are striving to restore safeguards for a variety [...]

ScienceDaily (Sep. 4, 2008) — The theory that global warming may be contributing to stronger hurricanes in the Atlantic over the past 30 years is bolstered by a new study led by a Florida State University researcher. The study will be published in the Sept. 4 edition of the journal Nature.
Using global satellite data, FSU [...]

ScienceDaily (Sep. 8, 2008) — A group of scientists affiliated with the International Geosphere-Biosphere Programme (IGBP) have proposed a new framework to account more accurately for the effects of aerosols on precipitation in climate models. Their work appears in the 5 September issue of Science magazine.
The increase in atmospheric concentrations of man-made aerosols—tiny particles suspended [...]

ScienceDaily (Sep. 7, 2008) — Permafrost blanketing the northern hemisphere contains more than twice the amount of carbon in the atmosphere, making it a potentially mammoth contributor to global climate change depending on how quickly it thaws.
So concludes a group of nearly two dozen scientists in a paper appearing this week in the journal Bioscience. [...]

ScienceDaily (Sep. 6, 2008) — Much has been said about the situation of the glaciers in Greenland and Antarctica, but little is known about those in the high mountain areas of the Iberian Peninsular. A Spanish research study has revealed, for the first time, that now only the Pyrenees has active glaciers.
Furthermore, the steady increase [...]

Expansion endangers public health and environment
September 4, 2008
Richmond, CA — Environmental justice groups, represented by lawyers from Earthjustice and Communities for a Better Environment, filed a lawsuit today challenging the Richmond City Council’s approval of Chevron’s refinery expansion project.
At issue is an environmental review that concealed that the project would result in much higher levels [...]

ScienceDaily (Sep. 3, 2008) — The growing number of dams and other impoundments is increasing the number of invasive species and the speed at which they spread, putting natural lakes at risk, says a study led by the University of Colorado at Boulder.
The research team combined data on water chemistry, the distribution of five “nuisance [...]

ScienceDaily (Sep. 2, 2008) — A new assessment more than doubles previous estimates of the amount of carbon stored in permafrost, and indicates that carbon dioxide emissions from microbial decomposition of organic carbon in thawing permafrost could amount to roughly half those resulting from global land-use change during this century.
The thawing of permafrost in northern [...]

ScienceDaily (Aug. 30, 2008) — Researchers examining images of gullies on the flanks of craters on Mars say they formed as recently as a few hundred thousand years ago and in sites once occupied by glaciers. The features are eerily reminiscent of gullies formed in Antarctica’s mars-like McMurdo Dry Valleys.
The parallels between the Martian gullies [...]
