Fossil Fuel CO2 Emissions Up By 29 Percent Since 2000 London, UK (SPX) Nov 18, 2009 
The strongest evidence yet that the rise in atmospheric CO2 emissions continues to outstrip the ability of the world's natural 'sinks' to absorb carbon is published in the journal Nature Geoscience. An international team of researchers under the umbrella of the Global Carbon Project reports that over the last 50 years the average fraction of global CO2 emissions that remained in the ... read moreNASA Conducts Airborne Science Aboard Zeppelin Airship 
Moffett Field CA (SPX) Oct 19, 2009NASA launched its first airborne science mission this week featuring a 246-foot-long Zeppelin NT airship equipped with two imaging instruments to learn more about environmental conditions in the San Francisco Bay Area. Scientists from NASA Ames Research Center's Earth Science Division are collaborating with Airship Ventures Inc., Moffett Field, Calif., to conduct experiments using the ... more

Missing Link To Cloud Formation Found
Copenhagen, Denmark (SPX) Aug 19, 2009The discovery of an unknown hitherto chemical compound in the atmosphere may help to explain how and when clouds are formed. The discovery of the so called dihydroxyepoxides (an aerosol-precursor), is reported in this week's issue of Science by a team comprising of researchers from the California Institute of Technology (Caltech) and the University of Copenhagen (UoC). Professor Henrik ... more Aura Marks Five Years Of Sky-High Atmosphere Research 
Pasadena CA (JPL) Aug 05, 2009Imagine Earth without an atmosphere - without clouds, wind or air. Earth's atmosphere protects, transports, and reacts to life on Earth. Without our ozone layer, the surface of Earth would be subject to harsh radiation coming from the sun. Without good quality air, public health and ecosystems suffer. And changes in the makeup of the atmosphere - such as to carbon dioxide, methane, nitrous oxide ... more Hong Kong proposes new air quality targets 
Hong Kong (AFP) July 23, 2009Hong Kong on Thursday laid out a series of proposals to tackle the city's poor air quality, but the move drew criticism from environmental groups who said new targets did not go far enough. Environment Secretary Edward Yau unveiled the targets to reduce pollutants like sulphur dioxide, nitrogen dioxide and particulates. If implemented, they would be the first new air quality targets in Hong ... more Massive dust storm in China circled the world in 13 days: study 
Paris (AFP) July 20, 2009A wind storm that ripped across western China's Taklimakan desert kicked up hundreds of thousands of tonnes of dust that high-altitude winds then carried around the world in less than two weeks, a study says. On May 8-9, 2007 winds reaching up to 36 kilometers (22.5 miles) per hour blew an estimated 800,000 tonnes of dust into the air, according to satellite imaging and computer models. ... more |

SKoreans buy air purifiers amid "yellow dust" warning
Seoul (AFP) Feb 27, 2009South Koreans are stocking up on air purifiers following a forecast of especially severe "yellow dust" storms from China and Mongolia this spring, officials said Friday. Forecasters say the annual dust storms will be particularly bad this spring because north China and the deserts of Mongolia, where they originate, suffered the worst drought in 50 years. The temperature there is also two ... more More Reasons To Hate Humidity 
College Station TX (SPX) Feb 25, 2009Here's yet another reason to hate humidity: it expands global warming, says a Texas A and M University professor. Andrew Dessler, a professor in the Department of Atmospheric Sciences who specializes in research on climate, says that warming due to increases in greenhouse gases will lead to higher humidity in the atmosphere. And because water vapor itself is a greenhouse gas, this ... more Scientist Models The Mysterious Travels Of Greenhouse Gas 
Chicago IL (SPX) Feb 19, 2009The global travel logs of greenhouse gases are based on atmospheric sampling locations sprinkled over the Earth and short towers that measure the uptake or release of carbon from a small patch of forest. But those measurements don't agree with current computer models of how plants and soils behave. A University of Michigan researcher is developing a unique way to reconcile these crucial ... more Global Warming May Delay Recovery Of Stratospheric Ozone 
Baltimore MD (SPX) Feb 12, 2009Increasing greenhouse gases could delay, or even postpone indefinitely the recovery of stratospheric ozone in some regions of the Earth, a new study suggests. This change might take a toll on public health. Darryn W. Waugh, an atmospheric scientist at Johns Hopkins University in Baltimore, and his colleagues report that climate change could provoke variations in the circulation of air in ... more |
