Image 1 - NOAA Greenhouse Gas Index On The Rise
2011-11-10 10:06:45

[ Watch the Video ] NOAA´s updated Annual Greenhouse Gas Index (AGGI), which measures the direct climate influence of many greenhouse gases such as carbon dioxide and methane, shows a continued steady upward trend that began with the Industrial Revolution of the 1880s. Started in 2004, the AGGI reached 1.29 in 2010. That means the combined heating effect of long-lived greenhouse gases added to the atmosphere by human activities has increased by 29 percent since 1990, the...

  Despite the reduced amount of carbon dioxide given off by the burning of natural gas, increasing use of it and decreasing our reliance on coal would do little to slow down global climate change, claims a new study set for publication in the journal Climatic Change Letters. The research, led by Tom Wigley, a senior research associate at the National Center for Atmospheric Research (NCAR), "underscores...the complex and sometimes conflicting ways in which fossil fuel burning...

Research at Greenland and Antarctic shows decline in methane and ethane levels Recent data from NSF-funded research in both Greenland and Antarctica demonstrate that fossil-fuel related emissions of both methane and ethane, two of the most abundant hydrocarbons in the atmosphere, declined at the end of the twentieth century, according to a paper published Thursday in the journal Nature. The causes of the decline in methane emission rates to the atmosphere have been puzzling scientists for...

A technical comment published in the current (May 27) edition of the journal Science casts doubt on a widely publicized study that concluded that a bacterial bloom in the Gulf of Mexico consumed the methane discharged from the Deepwater Horizon well. The debate has implications for the Gulf of Mexico ecosystem as well as for predictions of the effect of global warming, said marine scientist and lead author Samantha Joye, University of Georgia Athletic Association Professor in Arts and...

Two scientists describe their research on the fate of massive methane releases from the Gulf oil spill during the summer and fall of 2010 Methane, a potent greenhouse gas, seeps naturally from the seafloor in many places around the planet, including in the Gulf of Mexico. Scientists know that some of the Gulf's naturally released methane is eaten by microbes, but researchers are still trying to determine how much of this released methane ever reaches the atmosphere, where it may influence...

University of Alberta researchers have determined that the influence of northern peatlands on the prehistorical record of climate change has been over estimated, but the vast northern wetlands must still be watched closely as the planet grapples with its current global warming trend. Northern peatlands, which are a boggy mixture of dead organic material and water, cover more than four million square kilometers. The largest northern peatlands occur in the subarctic regions of Canada and...

Researchers develop technique to measure methane gas from cattle Methane is an extremely potent greenhouse gas. Wetlands, gas hydrates, permafrost, termites, oceans, freshwater bodies, non-wetland soils, are all natural sources of atmospheric methane; however, the majority of methane presence ca n be accredited to human-related activities. These activities include: such as fossil fuel production, biomass burning, waste management and animal husbandry. The release of methane into the...

ESA's Earth-observing satellites are helping to understand the intricate role that Eurasia's boreal forest "“ the planet's largest land ecosystem "“ plays in the chemical make-up of the atmosphere and the global climate system. By fostering new use of Earth observation data through the Atmosphere-Land Interaction Study (ALANIS), insight is being gained into how boreal forests contribute to greenhouse gas and aerosol concentration, and into the processes governing the interplay...

Concentrations of greenhouse gases approached record levels in 2009 and could set off even greater methane emissions from the Arctic, the UN's weather agency warned Wednesday. "Greenhouse gas concentrations have reached record levels despite the economic slowdown. They would have been even higher without the international action taken to reduce them," Michael Jarraud, secretary general of the World Meteorological Organization (WMO), said in a Wednesday press release. "In addition, potential...

Methane in the atmosphere of Mars lasts less than a year, according to a study by Italian scientists. Sergio Fonti (Università del Salento) and Giuseppe Marzo (NASA Ames) have used observations from NASA's Mars Global Surveyor spacecraft to track the evolution of the gas over three Martian years.  They presented their results at the European Planetary Science Congress in Rome on Tuesday September 21st. "Only small amounts of methane are present in the Martian...
