Latest Greenhouse gases Stories

Sometimes a picture really is worth a thousand words, particularly when the picture is used to illustrate science. Technology is giving us better pictures every day, and one of them is helping a NASA-funded scientist and her team to explain the behavior of a greenhouse gas.Google Earth -- the digital globe on which computer users can fly around the planet and zoom in on key features -- is attracting attention in scientific communities and aiding public communication about carbon dioxide....

The airline industry is set to vow to cut its carbon dioxide emissions by 50 percent of 2005 levels by 2050.On Tuesday, British Airways Chief Executive Willie Walsh is to announce the new decision reached by the airline industry that will aim for a 50 percent reduction of emissions by mid century.The announcement will come during a presentation to the UN forum on climate change in New York on Tuesday.Aviation currently makes up 1.6 percent of all global greenhouse gas emissions.The Guardian...

ROSEMONT, Ill., Sept. 18 /PRNewswire/ -- On 24 September, the dairy industry will make history signing a Global Dairy Agenda for Action during the World Dairy Summit in Berlin, Germany. Signed by seven organisations on behalf of the world's dairy associations and companies, the Global Dairy Agenda for Action is an industry pledge to reduce carbon emissions as part of its contribution to help address global warming. This pledge builds on past performance to address climate change. The...

NOAA has released the first-ever study of the climate impacts of the man-made substance, nitrous oxide.Researchers A.R. Ravishankara, J.S. Daniel and Robert W. Portmann of the National Oceanic and Atmospheric Administration's Earth System Research Laboratory (ESRL), said that nitrous oxide, also known as laughing gas, has become the largest ozone-depleting substance emitted through human activities.Additionally, the gas is expected to continue its status through the 21st century."Nitrous...

The UN's top climate scientist says he supports ambitious goals of reducing greenhouse gas emissions.In an interview with AFP, Rajendra Pachauri, Chairman of the Intergovernmental Panel on Climate Change (IPCC), said that his position does not allow him to make recommendations."But as a human being I am fully supportive of that goal. What is happening, and what is likely to happen, convinces me that the world must be really ambitious and very determined at moving toward a 350...

Canadian scientists say stressed crops emit more methane than thought and could result in a bigger global warming problem than currently forecast. University of Calgary scientists said when crops are exposed to environmental factors that are part of climate change -- increased temperature, drought and ultraviolet-B radiation -- some plants show enhanced methane emissions. And methane is a significant greenhouse gas; 23 times more effective in trapping heat than carbon dioxide. Most studies...

Scientists at the University of Calgary have found that methane emission by plants could be a bigger problem in global warming than previously thought.A U of C study says that when crops are exposed to environmental factors that are part of climate change -- increased temperature, drought and ultraviolet-B radiation -- some plants show enhanced methane emissions. Methane is a very potent greenhouse gas; 23 times more effective in trapping heat than carbon dioxide."Most studies just look...

A previously unrecognized player in the process by which gases produced by trees and other plants become aerosols"”microscopically small particles in the atmosphere"”has been discovered by a research team led by scientists at the California Institute of Technology (Caltech).Their research on the creation and effects of these chemicals, called epoxides, is being featured in this week's issue of the journal Science.Paul Wennberg, the R. Stanton Avery Professor of Atmospheric Chemistry and...

MAHWAH, N.J., Aug. 3 /PRNewswire/ -- Directravel, a leading corporate travel management company, today announced the availability of two new CO2 tracking reports - the CO2 Air Summary Report and a CO2 Combined (Air/Car/Hotel) Summary Report, available through its reporting package. These reports were designed in response to client requests for an easy way to track CO2 usage on various domestic and international trips and compare them to alternative travel methods. The Air Summary report...

Current methods for estimating greenhouse gas emissions have limitations that make it difficult to monitor CO2 emissions and verify an international climate treaty, says a new National Research Council letter report to the administrator of NASA, Charles F. Bolden Jr.NASA's Orbiting Carbon Observatory -- which failed to launch in February -- would have offered proof that greenhouse gas emissions could be monitored from space, as well as provided baseline data on CO2 emissions trends from a...
