Congressional deadlock and new scientific insights force new direction. The news on the avoid-dangerous-climate-change front seems to get ever bleaker. On the Policy Side, Little to No Progress The probability of a U.S. policy to curb greenhouse gas emissions any time soon is as close to zero as you can get — President Obama said…

Highlights from a workshop on the environmental and social implications of fracking. A group of the nation’s leading experts on energy and the environment are at Duke this week attending a workshop to try to ferret out the facts (and tamp down the hype) around shale gas and fracking, the controversial method for extracting natural…

Comments Off on Fight Over Tar Sands Pipeline May Lead to Cancellation, “Huge” Consequences

In November, the Obama administration decided to delay a decision on whether to approve the Keystone XL pipeline to bring tar sands from Canada to the United States. But in December, Republicans attached a provision to a tax bill, which President Obama signed, that urges the administration to decide on the pipeline within 60 days,…

That advice, particularly in America, typically revolves around food. But as…

A smoking gun in the form of methane isotopes links the two. Shale Gas: Game Changer or Potential Problem? The abundant, cleaner-burning fossil fuel known as shale gas has been hailed as a bridge fuel that’ll allow the transition from coal to a renewable-fueled future. Not only that, drilling for shale gas has propped up…

Nobody likes a methane leak. Now, now, don’t go there. We’re talking about leaks from natural gas production — and more specifically from horizontal drilling and hydrofracturing (or fracking) to extract natural gas locked inside shale. A look at the seesaw saga of the so-called bridge fuel to a bright, clean, renewable-fueled future. First came the natural gas “gold rush” …

The Shale Quandary

Two of its key conclusions: Total U.S. emissions of carbon dioxide (CO2) and other greenhouse gases were down by about 5.8 percent relative to 2008 — a…

Comments Off on Our Sustainable Earth

As scientists assess mounting evidence of a new geologic epoch where human activities will largely control the evolution of our Earth’s environment, they have coined this epoch, “The Anthropocene.” Don’t look now, but you’re living in it.   What we don’t know is whether our influence on climate during the Anthropocene will be a short-term, relatively…
