How EPA Could Cut National Methane Leaks Almost in Half

2014-11-21 06:00:00| Climate Ark Climate Change & Global Warming Newsfeed

ThinkProgress: Three top environmental groups released a report on Thursday detailing how the federal government could cut the country`s methane emissions almost in half. Methane is the primary component of natural gas. As the rise of hydraulic fracturing has lead to a boom in natural gas (as well as oil) production in North America, it`s also become apparent that methane has a tendency to leak into the atmosphere at various points in the industry`s infrastructure. That`s a problem, because methane is an extremely...

NASA findings show no excessive methane emissions from Alaska

2014-11-19 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed

Anchorage Dispatch: Though Arctic Alaska is warming and permafrost is thawing, the area so far has been spared from the scourge of excessive methane emissions, according to data collected by a NASA-managed research project. Concentrations of methane measured in the atmosphere over Alaska from May to September 2012 -- the first of five seasons for NASAs Carbon in Arctic Reservoirs Vulnerability Experiment, or CARVE -- turned out to be about equal to the global average for a similar-sized area. The findings, gleaned...

Alaska Shows no Sign of Rising Methane Levels, For Now

2014-11-15 00:04:00| Climate Ark Climate Change & Global Warming Newsfeed

Nature World: Climate scientists will be happy to hear that Alaska, despite large temperature increases in recent decades, is showing no signs of rising methane levels, at least for now. Previous studies had suggested that methane from Alaskan soils was being released at unusually high rates, but the new NASA-led study, suggests otherwise, and "That's good news, because it means there isn't a large amount of methane coming out of the ground yet," lead author Rachel Chang said in a news release. Methane is...

Methane cuts won't buy us time on climate change

2014-11-05 19:18:00| Climate Ark Climate Change & Global Warming Newsfeed

New Scientist: WE CAN'T get around it. To prevent dangerous climate change, there is no alternative to ending human emissions of carbon dioxide. Suggestions that cutting other greenhouse gases such as methane might do part of the job are based on faulty accounting, according to a new study. This finding reinforces the conclusions of the latest report by the Intergovernmental Panel on Climate Change (IPCC), which on Sunday called for an end to all CO2 emissions by 2100 to prevent what it called "severe, widespread,...
