Horizontal drilling, fracking begins in old, shallow oil and gas fields

2013-09-21 23:21:00| Climate Ark Climate Change & Global Warming Newsfeed

Post-Gazette: If we could take a tiny glass elevator down the trajectory of a Marcellus Shale well, we would see slabs of coal, sandstone, shale and siltstone alternating and colliding with one another for thousands of feet until we finally reach the target rock. Today, half a dozen local oil and gas companies are forgoing the full ride. They're getting off the elevator halfway down, before the Elk Sandstone formation that separates the conventional oil and gas reservoirs from the deeper, unconventional plays...

Study Revises Estimate of Methane Leaks from U.S. Fracking Fields

2013-09-16 23:15:00| Climate Ark Climate Change & Global Warming Newsfeed

Scientific American: Environmental controls designed to prevent leaks of methane from newly drilled natural gas wells are effective, a study has found -- but emissions from existing wells in production are much higher than previously believed. The findings, reported today in the Proceedings of the National Academy of Sciences, add to a burgeoning debate over the climate impact of replacing oil- and coal-fired power plants with those fuelled by natural gas. Significant leaks of heat-trapping methane from natural gas...

2013-09-06 16:49:00| Climate Ark Climate Change & Global Warming Newsfeed

James West: For years, the question of what to do about climate change has toppled Aussie leaders and divided the country. Will Saturday`s election bring peace? As you watched last year`s US election, did you find yourself aggrieved by the lack of big climate change talk from your leaders? Well, I have an election you`re going to want to watch. This weekend, a nation gripped to the point of near-hysteria over carbon abatement policies (yes, there is such a country) will finally put to rest an epic struggle...
