November 2009 Geology and GSA Today highlights Oct 31, 2009
Besides forming parts of important hydrocarbon and water reservoirs, these grains have provided valuable insights into paleoceanography, oceanic and atmospheric chemistry, and the conditions in which carbonate sediments were deposited. Although ooids occur throughout geologic time and are in great abundance in some areas today, it remained a puzzle as to why they had not been recognized in modern sediments on any atoll in the Pacific Ocean.

* Geo-engineering: A mere sticking plaster for an ailing planet? Oct 25, 2009
Earlier this year, Vaughan published a paper with UEA colleague Tim Lenton in the journal Atmospheric Chemistry and Physics Discussions, comparing different schemes to cool the Earth. They concluded that stratospheric aerosols had by far the greatest potential to combat warming in the timescale to 2050, given their relatively low cost and high efficiency.

Key new ingredient in climate model refines global predictions Oct 10, 2009
"In order to do these experiments in the climate system model, expertise is needed in the nitrogen cycle, but there is also a need for climate modeling expertise, the ocean has to be involved properly, the atmospheric chemistry . . . and then there are a lot of observations that have been used to parameterize the model," said Thornton, who works in ORNL's Environmental Sciences Division. "The biggest challenge has been bridging this multidisciplinary gap and demonstrating to the very broad range... (EurekAlert!)

Crutzen, who wasnt part of todays study, shared the 1995 Nobel Prize for Chemistry for his research into ozone. (Bloomberg -- Germany)
New hope for intelligent life elsewhere Aug 14, 2009
"A gamma ray burst won't affect whether life will begin at some particular point in time, but it would affect how quickly life develops or takes hold by causing changes in atmospheric chemistry on the planet," Cirkovic said. "This can be interpreted as resetting astrobiological clocks which tick on each habitable planet in the Milky Way.". (MSNBC -- Technology)

Ozone, nitrogen change the way rising CO2 affects Earth's water Jul 10, 2009
The researchers concluded that models of climate change may be underestimating how much water is likely to run off the land and back into the sea as atmospheric chemistry changes. Runoff may be as much as 17 percent higher in forests of the eastern United States when models account for changes in soil nitrogen levels and atmospheric ozone exposure. (EurekAlert!)
Hoax being driven by extremists Jul 10, 2009
I like your post, but I have to say (from a meteorologist's perspective) that there is more to the story than atmospheric chemistry. Sure the combined effects may cause temporary warming, but the warming should increase evaporation rates over the ocean, which should produce more cloud cover and precipitation. (Missoulian, MT)
