*History of influence of industrial revolution hidden in glacial ice*
New clues about how Earth’s remote ecosystems have been influenced by the industrial revolution have been uncovered. Until now they were locked away, frozen in the ice of glaciers.
So say scientist Aron Stubbins of the Skidaway Institute of Oceanography and colleagues. (more…)
*Disruption of wind shear enables stronger storms*
Pollution is making Arabian Sea cyclones more intense, according to a study in this week’s issue of the journal Nature.
Traditionally, prevailing wind shear patterns prohibit cyclones in the Arabian Sea from becoming major storms.
The Nature paper suggests that weakening winds have enabled the formation of stronger cyclones in recent years–including storms in 2007 and 2010 that were the first recorded storms to enter the Gulf of Oman. (more…)
California is showing the way for the rest of the nation in terms of reducing greenhouse gas emissions, having set an ambitious goal to reduce these emissions to 80 percent below 1990 levels by the year 2050. Given that energy demand is projected to double by 2050, experts agree that the state will have to dramatically overhaul its energy systems to achieve its greenhouse gas emission goals.
At the 2011 Annual Meeting of the American Association for the Advancement of Science, some of the specific challenges and issue ahead were discussed in a session titled “Portraits of the California Energy System in 2050: Cutting Emissions by 80 Percent.” Contributing to this discussion were two scientists from Berkeley Lab and one from the Energy Biosciences Institute (EBI), in which Berkeley Lab is a partner.

*Using a flood simulator, MU researchers reveal cottonwood trees as a profitable crop in devastated flood areas*
COLUMBIA, Mo. –When the Missouri River flooded in 1993 and 1995, it left a deep layer of sandy silt that covered thousands of acres of rich farmland. Now, MU forestry researchers may have found a crop that can survive a flood and act as a sustainable source of biomass.
