Swedish and Indian researchers constrain the sources of climate- and health-afflicting soot pollution over South Asia A gigantic brownish haze from various burning and combustion processes is blanketing India and surrounding land and oceans during the winter season. This soot-laden Brown Cloud is affecting South Asian climate as much or more than carbon dioxide and cause premature deaths of 100 000s annually, yet its sources have been poorly understood. In this week's issue of Science...

Part of the changing climate, earlier spring snowmelt could affect hydropower generation, agriculture Soot from pollution causes winter snowpacks to warm, shrink and warm some more. This continuous cycle sends snowmelt streaming down mountains as much as a month early, a new study finds. How pollution affects a mountain range's natural water reservoirs is important for water resource managers in the western United States and Canada who plan for hydroelectricity generation, fisheries and...

POZNAN, Poland, Dec. 12 /PRNewswire-USNewswire/ -- As UN climate negotiators neared the end of two weeks of debate over measures to deal with the impacts of global climate change, island nations in the North and South Pacific struggled to cope with a new round of devastating tidal surges that brought severe flooding to low-lying regions over thousands of square miles. A low-pressure system, coinciding with high tides, generated nine- to ten-foot waves and tidal surges that swept over atolls...

Poznan Panel of Experts Discuss Importance of Black Carbon, the Montreal Protocol, Biochar, and Methane as Part of Global Climate Strategy POZNAN, Poland, Dec. 11 /PRNewswire-USNewswire/ -- The world is already close to passing the tipping points for abrupt climate change events, and if strong measures aren't taken immediately the results will be catastrophic, concluded panelists during a side event at the UN climate conference in Poznan Tuesday night. Both scientific experts and government...

Soot is tarnishing the ice in the Arctic and adding a swiftness to the melting that could cause the ocean in the North Pole to be without any ice well before 2050, experts announced on Tuesday. Experts stated that in order to resist the impact of global warming in the Arctic, we should re-focus and center more on stopping the industrial greenhouse gasses like soot, ozone and methane in Europe, North America and Russia. Soot darkens the ice which causes it to absorb heat, increasing the speed...

A detailed analysis of black carbon -- the residue of burned organic matter -- in computer climate models suggests that those models may be overestimating global warming predictions. A new Cornell study, published online in Nature Geosciences, quantified the amount of black carbon in Australian soils and found that there was far more than expected, said Johannes Lehmann, the paper's lead author and a Cornell professor of biogeochemistry. The survey was the largest of black carbon ever...

By Barbara Swan Alliant Energy Alliant Energy is faced with the dual challenge of providing safe, reliable and affordable energy - in a time when demand is rising 2 to 3 percent each year - and protecting the environment. We believe we've struck a balance between the two with the proposed expansion of our Nelson Dewey Generating Station in Cassville, Wis. Environmentally, Alliant Energy takes seriously its commitment to protecting the environment and reducing the amount of emissions at...

A new federal science report noted heavy smog hanging over Beijing could heat up the weather in the American Midwest by three degrees over the next 50 years. The report said unlike the long-lived greenhouse gas carbon dioxide, the particle and gas pollution only stays in the air for a few days or weeks but its warming effect on the climate half a world away could last for decades. "We found that these short-lived pollutants have a greater influence on the Earth's climate throughout the 21st...

Tugboats puff out more soot for the amount of fuel used than other commercial vessels, and large cargo ships emit more than twice as much soot as previously estimated, according to the first extensive study of commercial vessel soot emissions. Scientists from NOAA and the University of Colorado conducted the study and present their findings in the July 11 issue of the journal Geophysical Research Letters. The primary sources of soot, or small particles of black carbon, are fossil fuel...

Long-term Survey Will Profile Pollutants to Determine Their Origination.Using sophisticated unmanned aircraft, research scientists at Scripps Institution of Oceanography, UC San Diego hope to assess Southern California's potential for climate change and better understand the sources of air pollution.Funded by the California Energy Commission, the California AUAV Air Pollution Profiling Study (CAPPS) uses autonomous unmanned aerial vehicles (AUAVs) to gather meteorological data as the aircraft...

Word of the Day
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
