Image 1 - HIPPO Takes To The Skies To Get A Taste Of Earth's Atmosphere

The HIAPER Pole-to-Pole Observation (HIPPO) project generated an extraordinarily detailed mapping of the global distribution of greenhouse gases, black carbon and related chemical species in the atmosphere Once international agreements demand it, effective, enforceable greenhouse gas reduction will require in-depth information on the fluxes and transports of these and other atmospheric constituents. Researchers know that concentrations of aerosols like black carbon and gases like carbon...

“Albedo Effect” In Forests Can Cause Added Warming, Bonus Cooling
2011-10-20 06:10:28

Wildfire, insect outbreaks and hurricanes destroy huge amounts of forest every year and increase the amount of carbon dioxide entering the atmosphere, but scientists are now learning more about another force that can significantly affect their climate impact. Researchers conclude in a new study that the albedo effect, which controls the amount of energy reflected back into space, is important in the climatic significance of several types of major forest disturbances. In some cases...

Cities release more heat to the atmosphere than the rural vegetated areas around them, but how much influence these urban "heat islands" have on global warming has been a matter of debate. Now a study by Stanford researchers has quantified the contribution of the heat islands for the first time, showing that it is modest compared with what greenhouse gases contribute to global warming. "Between 2 and 4 percent of the gross global warming since the Industrial Revolution may be due to urban...

People who cycle through London and other major cities have higher levels of black carbon in their airway cells, experts from the UK have shown. The research, which will be presented at the European Respiratory Society's Annual Congress in Amsterdam today (25 September 2011), suggests that cyclists inhale more black carbon than pedestrians, which may cause damage to the lungs. The combustion of fossil fuels results in the generation of large numbers of inhalable particles of soot (black...

Climate change may still increase the pollution load Trends in the concentrations of nearly sixty atmospheric pollutants have been studied using the data collected in Finland at the Pallas-Sodankylä Observatory from 1996 to 2009. Concentrations of pollutants in Lapland are very low, typically about one tenth of the background concentrations in Southern Finland. Many of the concentrations studied remained unchanged over the long term and nearly half showed a decreasing trend....

Image 1 - Emissions From Deepwater Horizon Controlled Burns

  During the 2010 BP/Deepwater Horizon Gulf oil spill, an estimated one of every 20 barrels of spilled oil was deliberately burned off to reduce the size of surface oil slicks and minimize impacts of oil on sensitive shoreline ecosystems and marine life. In response to the spill, NOAA quickly redirected its WP-3D research aircraft to survey the atmosphere above the spill site in June. During a flight through one of the black plumes, scientists used sophisticated instrumentation on...

A new study of dust-like particles of soot in the air – now emerging as the second most important – but previously overlooked – factor in global warming provides fresh evidence that reducing soot emissions from diesel engines and other sources could slow melting of sea ice in the Arctic faster and more economically than any other quick fix, a scientist reported here today. In a presentation at the 242nd National Meeting & Exposition of the American Chemical Society...

How the frequency and intensity of wildfires and intentional biomass burning will change in a future climate requires closer scientific attention, according to CSIRO's Dr Melita Keywood. Dr Keywood said it is likely that fire "“ one of nature's primary carbon-cycling mechanisms "“ will become an increasingly important driver of atmospheric change as the world warms. "Understanding changes in the occurrence and magnitude of fires will be an important challenge for which there needs...

US and Swiss researchers have, for the first time, modelled a climate system with extremely high carbon emissions in an attempt to test the boundaries of the current computer simulation programs that inform us. Published today, Tuesday 5 July, in IOP Publishing's journal Environmental Research Letters, the study has revealed the potentially devastating effects that high carbon emissions could have on our climate. Little attention has previously been paid to the upper bound range of future...


Word of the Day
cruet
  • A vial or small glass bottle, especially one for holding vinegar, oil, etc.; a caster for liquids.
This word is Middle English in origin, and ultimately comes from the Old French, diminutive of 'crue,' flask.
