"Pondering Impact of Drilling Off Remote Northwest Alaska"

The planned oil-drilling in the Chukchi Sea off Alaska's coast could bring spills harder to control than the Deepwater Horizon blowout. For centuries, native Inupiat have huted bowhead whales, bearded seals, walruses, and Caribou here.

"Climate Scientists Shine New Light On Methane Mystery"

"Atmospheric levels of methane, 20 times more powerful than carbon dioxide (CO2) at trapping heat, stayed steady for two decades to 2006 on wider fertilizer use to grow rice or a surge in natural gas demand, according to two separate studies in the journal Nature.

Climate researcher Fuu Ming Kai from the Massachusetts Institute of Technology's Singapore research center said in one study that methane output from rice fields in the Northern Hemisphere dropped during the period as fertilizers replaced manure and because of reduced water use.
