Denver to Barcelona: Global cities and greenhouse gas emissions
Denver released the largest amount of greenhouse gases (GHG) and Barcelona the smallest amount in a new study documenting how differences in climate, population density and other factors affect GHG emissions in global cities. view more (2009-09-24)
Scientists take off on historic mission to measure greenhouse gases that have an impact on climate
HIAPER, one of the nation's most advanced research aircraft, is scheduled to embark on an historic mission spanning the globe from the Arctic to the Antarctic. view more (2009-01-08)
Stripped down: Hubble highlights 2 galaxies that are losing it
Ram pressure is the drag force that results when something moves through a fluid - much like the wind you feel in your face when bicycling, even on a still day - and occurs in this context as galaxies orbiting about the centre of the cluster move through the intra-cluster medium, which then sweeps out gas from within the galaxies. view more (2009-09-30)
Tech researchers using nanotechnology in biofuel process to save money, environment
Dr. James Palmer, associate professor of chemical engineering at Louisiana Tech University, is collaborating with fellow professors Dr. Yuri Lvov, Dr. Dale Snow, and Dr. Hisham Hegab to capitalize on the environmental and financial benefits of "biofuels" by using nanotechnology to further improve the cellulosic ethanol processes. view more (2009-10-09)
Research finds that Earth's climate is approaching 'dangerous' point
NASA and Columbia University Earth Institute research finds that human-made greenhouse gases have brought the Earth's climate close to critical tipping points, with potentially dangerous consequences for the planet. view more (2007-06-01)
Discovery is a step towards pollution-free cars
Scientists have made a world-first discovery which is a step towards using environmentally-friendly hydrogen to power our cars. view more (2004-10-13)
Economical, nonpolluting solutions to greenhouse growing found
A recent study of an ancient growing medium has implications for advancing growth and yield of greenhouse crops grown in soilless conditions. view more (2007-10-31)
Confirmed - deforestation plays critical climate change role
Dr Pep Canadell, from the Global Carbon Project and CSIRO Marine and Atmospheric Research, says today in the journal Science that tropical deforestation releases 1.5 billion tonnes of carbon each year into the atmosphere. view more (2007-05-14)
Safe Heating of Explosive Gases
The Institut für Mikrotechnik Mainz GmbH (IMM) has developed the micro structured gas heater MSGH for combustible or explosive media. A clear separation of the space containing the medium from the heating elements allows safe heating and overheating of process gases, gas mixtures or gas/vapour mixtures. The MSGH has 50 cubic centimetres of... view more... (2004-06-23)
Good News about $4 Gas? Fewer Traffic Deaths
As unwelcome as they are, higher gasoline prices do come with a plus side - fewer deaths from car accidents, says a researcher at the University of Alabama at Birmingham (UAB). view more (2008-07-11)
UCLA researchers solve decade-old mystery
Environmentally friendly hydrogen gas fueled vehicles can dramatically reduce greenhouse gas emissions and lessen the country's dependence on sources of fossil fuel. Though several hydrogen vehicles exist on the market today, there is still much room for improvement in the way that hydrogen is stored on-board the vehicle. view more (2008-02-27)
Hot volcanic eruptions could lead to a cooler Earth
Volcanic eruptions may be an agent of rapid and long-term climate change, according to new research by British scientists. view more (2005-06-13)
Expect a Warmer, Wetter World this Century, Computer Models Agree
Recent episodes of deadly heat in the United States and Europe, long dry spells across the U.S. West, and heavy bursts of rain and snow across much of North America and Eurasia hint at longer-term changes to come, according to a new study based on several of the world's most advanced climate models. view more (2006-10-23)
Methane Release Could Cause Abrupt, Far-Reaching Climate Change
An abrupt release of methane, a powerful greenhouse gas, from ice sheets that extended to Earth's low latitudes some 635 million years ago caused a dramatic shift in climate, scientists funded by the National Science Foundation (NSF) report in this week's issue of the journal Nature. view more (2008-05-29)
11 leading national experts reach consensus on beneficial biofuels
"Done right," biofuels can be produced in large quantities and have multiple benefits, but only if they come from feedstocks produced with low life-cycle greenhouse gas emissions, as well as minimal competition with food production. view more (2009-07-17)
Global atmospheric carbon level may depend primarily on Southern Ocean
Circulation in the waters near the Antarctic coast may be one of the planet's critical means of regulating levels of carbon dioxide in the Earth's atmosphere, according to Princeton researchers. view more (2006-06-23)
Alstom And Rolls-Royce Sign Long-term Technology Agreement
ALSTOM and Rolls-Royce announced today (13 February 2002) that they have signed a long-term technology agreement which will enable ALSTOM to use Rolls-Royce aero engine technology in the development of its heavy duty gas turbine product range. This agreement is in line with ALSTOM's long-term strategy to offer a highly-competitive heavy duty gas... view more... (2002-02-13)
Researchers identify energy gains and environmental impacts of corn ethanol and soybean biodiesel
The first comprehensive analysis of the full life cycles of soybean biodiesel and corn grain ethanol shows that biodiesel has much less of an impact on the environment and a much higher net energy benefit than corn ethanol, but that neither can do much to meet U.S. energy demand. view more (2006-07-12)
North Pole's ancient past holds lessons for future global warming
Detailed information on greenhouse gasses and a subtropical heat wave at the North Pole 55 million years ago is providing information about the Earth's past as well as a portent for its future, according to reports in the June 1 issue of Nature. view more (2006-06-01)
Fire is important part of global climate change, report scientists
Fire must be accounted for as an integral part of climate change, according to 22 authors of an article published in the April 24 issue of the journal Science. The authors determined that intentional deforestation fires alone contribute up to one-fifth of the human-caused increase in emissions of carbon dioxide, a heat-trapping gas that raises... view more...
