"Over the past four years, the Republican Party has undergone a fairly dramatic shift in its approach to energy and environmental issues. Global warming has disappeared entirely from the party’s list of concerns. Clean energy has become an afterthought. Fossil fuels loom larger than ever. And one way to see this shift clearly is to compare the party’s 2008 and 2012 platforms."
"The Obama Administration [Thursday] gave Shell approval to prepare for oil drilling in environmentally fragile Chukchi Sea off Alaska although a critical oil spill containment vessel has not been certified.

"Torrential rainfall from Hurricane Isaac hurt rice, cotton, soybean and sugar cane crops in the Deep South, but elsewhere the storm will bring relief to American farmers suffering from the worst drought in more than 50 years, an agricultural meteorologist said on Thursday."
"Louisiana officials on Thursday ordered people along the Tangipahoa River between the towns of Kentwood and Robert to evacuate due to the expected failure of a dam in Mississippi that was damaged by Tropical Storm Isaac."
"President Felipe Calderón of Mexico announced Wednesday that the national oil company, Pemex, had struck oil in deep water, its first success after years of exploration in the deeper reaches along the bottom of the Gulf of Mexico."
"A vast reservoir of the potent greenhouse gas methane may be locked beneath the Antarctic ice sheet, a study suggests. Scientists say the gas could be released into the atmosphere if enough of the ice melts away, adding to global warming."
"Before the Marine Mammal Protection Act was passed 40 years ago, early New Englanders had nearly hunted seals to death. They wanted them for their furs and to keep them from eating cod. Massachusetts even paid bounties on seals: $5 per nose. The act has helped gray seals and harbor seals recolonize New England waters, but fishermen off the coast of Cape Cod say they have become a nuisance."
"For decades, cowboys known as 'tick riders' have patrolled the U.S.-Mexico border to prevent cattle carrying 'fever ticks' from entering."
"West Nile virus cases nationally were up 40% from last week, now totaling 1,590, including 66 deaths, the Centers for Disease Control and Prevention said Wednesday."
The dramatic drop in the price of natural gas as a result of the U.S. fracking boom may doom the profitability of future coal-burning power plants. It is just one example of how imperfect information about the future makes energy markets uncertain and risky.
