Their studies will be presented in April at the American Chemical Society national meeting in New Orleans.
Rising temperatures due to climate change will reduce the availability of water in New England during the summer, when demand is highest, and increase sediment and pollution loads carried by rivers and streams. These changes are expected to impact agriculture, forestry, fisheries, water supply systems and hydroelectric power generation.
You know that green scum creeping across the surface of your local public water reservoir? Or maybe it's choking out a favorite fishing spot or livestock watering hole. It's probably cyanobacteria "“ blue-green algae "“ and, according to a paper in the April 4 issue of the journal Science, it relishes the weather extremes that accompany global warming.
Climate change may be predicted by fish who "eavesdrop" their way to healthy food sources using chemical cues given off by ocean organisms.

One cool year does not erase decades of climate data, nor does it more than minimally change the long-term climate trend, according to one of the world's foremost global climate scientists. Long-term climate change is just that "” long term "” and 12 months of data are little more than a blip on the screen.
A destructive spring freeze that chilled the eastern United States almost a year ago illustrates the threat a warming climate poses to plants and crops, according to a paper just published in the journal BioScience. The study was led by a team from the Department of Energy's Oak Ridge National Laboratory.

The bad news is that the Mississippi Delta is sinking as much as one fifth of an inch per year and sometimes even more. But the good news is that the sinking is mostly limited to the uppermost layer of sediment and the land underneath is much more stable.
To have meaningful impact on managing carbon emissions, we need to think about the problem globally. Integrating science and public policy with the needs of consumers and the global economy is critical if we have any chance of reducing the effects of carbon on the climate, say scientists at the 2008 Annual Meeting of the American Association for the Advancement of Science (AAAS).
