Former energy lobbyist and GOP presidential non-candidate Gov. Haley Barbour (MS) at a House hearing Thursday blamed the devastation of the Gulf oil spill not on BP, but on the news media for showing a "chocolate pelican."

"The operator of the stricken Japanese nuclear power plant said on Friday that more radioactive water could begin spilling into the sea later this month if there is a glitch in setting up a new decontamination system."

"Colorado State University forecasters predicted the Atlantic hurricane season that began on Wednesday would be a busy one with 16 tropical storms and nine of those growing into hurricanes."

"As residents confront a gigantic cleanup following the tornado that savaged Joplin, experts say environmental dangers could lurk amid the mountains of debris in the southwestern Missouri city and even in the water and air."

"Japan will pay schools near the quake-ravaged Fukushima nuclear power plant to remove radioactive top soil and set a lower radiation exposure limit for schoolchildren after a growing outcry over health risks."

"The annual G8 Summit concluded this afternoon with agreement among leaders of the world's largest industrial democracies to strengthen nuclear security in view of Japan's ongoing nuclear power plant crisis."
