"Royal Dutch Shell's bid to drill in the Arctic this summer took another step forward on Friday when the U.S. Interior Department approved its oil spill response plan for the Chukchi Sea."

"The U.S. and Mexico reached an agreement Monday to cooperate on oil and gas development in the Gulf of Mexico. Signed at a meeting in Los Cabos, Mexico, the agreement would set a process that U.S. companies and Mexico's state-owned Pemex could use to jointly develop waters that straddle the nations' maritime border. It also would provide for the U.S. and Mexican governments jointly to review applications and safety inspections in cases of drilling in the boundary-straddling waters, where oil spills could affect both nations."

"A Powerpoint presentation obtained by The Daily Caller shows that during a July 2008 meeting, the $789 million Rockefeller Brothers Fund proposed to coordinate and fund a dozen environmental and anti-corporate activist groups’ efforts to scuttle pipelines carrying tar sands oil from Canada to the United States."

"Climate scientist Peter Gleick has acknowledged that he was the person who convinced the Heartland Institute to hand over the contents of its January Board package, authenticating the documents beyond a doubt and further exposing the disinformation campaign Heartland has pursued in the last week, trying to discredit the information." [Gleick called his methods in obtaining the documents an ethical lapse, and the outpouring of criticism diverted media attention from the apparent deception campaign revealed in the Heartland documents themselves. The uproar raises important issues about what methods are legitimate for investigative journalists to use in obtaining information (Gleick was not a journalist), and where the solid ground of truthfulness may be found in today's escalating conflict between science and PR. -- Ed. note]

"Fort St. James, Canada -- The prime minister is talking about being 'held hostage' by U.S. interests. Radio ads blare, 'Stand up to this foreign bully.' A Twitter account tells of a 'secret plan to target Canada: exposed!'"

"A Southwest Florida conservation official is calling a federal judge's ruling on clean water limits a total victory for the environment. U.S. District Judge Robert Hinkle's ruling in Tallahassee on Saturday ended years of delays in setting and enforcing specific limits on sewage, manure and fertilizer contamination in Florida waters."

"The House by a wide margin [Thursday] night passed a bill to vastly expand oil and gas development off the nation's coasts, in an Alaskan reserve and on experimental shale tracts in the Intermountain West."

"Most scientists, on achieving high office, keep their public remarks to the bland and reassuring. Last week Nina Fedoroff, the president of the American Association for the Advancement of Science (AAAS), broke ranks in a spectacular manner. She confessed that she was now 'scared to death' by the anti-science movement that was spreading, uncontrolled, across the US and the rest of the western world."

"A slew of pathogens typically found in livestock and domestic animals is increasingly being found in marine mammals, including in the Strait of Georgia off Vancouver."

"Fine atmospheric particles — smaller than one-thirtieth of the diameter of a human hair — were identified more than 20 years ago as the most lethal of the widely dispersed air pollutants in the United States. Linked to both heart and lung disease, they kill an estimated 50,000 Americans each year. But more recently, scientists have been puzzled to learn that a subset of these particles, called secondary organic aerosols, has a greater total mass, and is thus more dangerous, than previously understood."
