"'I watch them die, young and old,' [Spokane tribal gravedigger Harold] Campbell said. 'I think it’s caused by the radiation.' The radiation is from the Northwest’s only open-pit uranium mines -- an all-but-forgotten chapter of Washington’s Cold War history."

As world demand for staples like wheat, rice, corn, and soy outpaces dwindling growth in agricultural production, food prices are rising and more people are hungry. Now experts are saying that climate change is playing a bigger role than they once expected.

"A climate change scientist who has been targeted by death threats says the science community must still continue to release the latest research."

"Some areas in the tropics face famine because of failing food production, an international research group says."

"North China is dying. A chronic drought is ravaging farmland. The Gobi Desert is inching south. The Yellow River, the so-called birthplace of Chinese civilization, is so polluted it can no longer supply drinking water. The rapid growth of megacities — 22 million people in Beijing and 12 million in Tianjin alone — has drained underground aquifers that took millenniums to fill."

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."

"BP succeeded in sinking the oil from its blown well out of sight — and keeping much of it away from beaches and marshes last year — by dousing the crude with nearly 2 million gallons of toxic chemicals. But the impact on the ecosystem as a whole may have been more damaging than the oil alone."

"The Energy Department ignored the law by shutting down a controversial Nevada nuclear waste site because of opposition within the state, Republican and Democratic lawmakers complained at a hearing on Wednesday."

"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."
