Control methane now, greenhouse gas expert warns

2014-05-16 01:46:00| Climate Ark Climate Change & Global Warming Newsfeed

ScienceDaily: As the shale gas boom continues, the atmosphere receives more methane, adding to Earth`s greenhouse gas problem. Robert Howarth, greenhouse gas expert and ecology and environmental biology professor, fears that we may not be many years away from an environmental tipping point -- and disaster. "We have to control methane immediately, and natural gas is the largest methane pollution source in the United States," said Howarth, who explains in an upcoming journal article that Earth may reach the point...

California greenhouse gas emissions inch up 2 percent

2014-05-15 00:05:00| Climate Ark Climate Change & Global Warming Newsfeed

Reuters: Californias greenhouse gas emissions rose about 2 percent in 2012 compared to the previous year as more natural gas was burned to compensate for the closure of a nuclear plant and a drop in hydro-electricity due to a drought, the states air regulator said on Wednesday. Higher utility sector emissions were offset somewhat by a modest decline in output from the transportation sector, which remains the states largest single source of heat-trapping greenhouse gas emissions. Emissions from manufacturers...

Fracking wont ensure greenhouse gas emissions reduction

2014-05-05 12:39:00| Climate Ark Climate Change & Global Warming Newsfeed

Blue and Green: A new study has argued that while there may be benefits brought by shale gas as a transition fuel, its usage would also lead to an increase in overall energy use and little or no greenhouse gas emissions reduction. The study, published in the journal Environmental Science and Technology, acknowledges that shale gas development in the US has contributed to keeping energy prices down at the expense of other energy sources such as coal, oil, nuclear and renewables. However, it also says that the...
