Australian greenhouse gases barely hit by carbon price
2013-12-14 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Sydney Morning Herald: Australia's greenhouse gas emissions were little changed in the first year of the carbon price, as emissions from sectors only partly covered by the tax nullified most of the cuts. Emissions for the 12 months to June totalled 545.9 million tonnes, 300,000 tonnes lower than a year earlier, the government's National Greenhouse Gas Inventory figures say. Emissions reductions from power plants fell, accelerating to an annual drop of 6.3 per cent - or cutting 12.2 million tonnes - from a 6.1 per...

Will Arctic meltdown produce more greenhouse gases or less?
2013-12-07 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
ClimateWire: In addition to being a warming hot spot, the Arctic plays a pivotal role in the movement of carbon between atmosphere, land and sea. But the degree to which Arctic regions are a carbon sink, versus a source of greenhouse gas, is still a matter of debate. Permafrost holds vast amounts of carbon long stored in cold conditions, for example, but scientists are trying to pinpoint the pace at which the carbon will be released into the atmosphere because of thawing of frozen soil. Similarly, there...
Destroying greenhouse gases in environmentally-friendly way
2013-11-28 17:31:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Researchers at the Universitat Jaume I (UJI) have developed a new catalyst for the "activation" of carbon-fluorine bonds. This process has many industrial applications, among which stands out the possibility to be used to reduce existing stocks of CFCs (chloro-fluoro-carbonated compounds), known as "greenhouse gases." CFCs experienced a huge boom in the 80s, but later they were found to destroy the ozone layer because of their photochemical decomposition when they reached the upper layers of the...

Pre-industrial rise in greenhouse gases had natural and anthropogenic causes
2013-11-22 16:59:00| Climate Ark Climate Change & Global Warming Newsfeed
Science Daily: For years scientists have intensely argued over whether increases of potent methane gas concentrations in the atmosphere - from about 5,000 years ago to the start of the industrial revolution - were triggered by natural causes or human activities. A new study, which will be published Friday in the journal Science, suggests the increase in methane likely was caused by both. Lead author Logan Mitchell, who coordinated the research as a doctoral student at Oregon State University, said the "early...
