What's changed, she thinks, may be that warmer water pouring into the sea from Siberia's north-flowing rivers have raised the sea-bottom temperature to the point where the methane, much of it stored under pressure in the form of methane hydrates, can begin to break free. Unlike the permafrost on land, says Shakhova, soil under the sea floor is always hovering at close to the melting point because of its proximity to unfrozen seawater. Anthropogenic (that is, human-caused) warming may be the last straw...
...very accurate over water. So while he considers Shakhova's data absolutely convincing, he's less convinced that these emissions are necessarily new. "In the context of the global methane cycle, has this been accelerating recently, or has it been going on for some time?" Heimann says. "It may be related to recent Arctic warming, but I don't know."

...Louis Majesty wasn't hit by a sudden storm or any of the other expected dangers of maritime travel. Rather, it may have been the victim of rogue waves. For centuries mariners have told stories about sudden waves that would emerge out of the open ocean without warning, strong enough to topple even large ships. The S.S. Waratah, which vanished on a journey to Cape Town; the M.S. München, lost en route to Savannah, Ga.; even the S.S. Edmund Fitzgerald, "the good ship and true" of the Gordon Lightfoot song, which disappeared on Lake Superior - all were rumored...
Rogue waves generally occur out in the open ocean. They may be the result of a number of factors coming together - strong winds and fast currents coinciding, for instance - or of a focusing effect, in which several smaller waves join together to form one big wave. There may even be a nonlinear effect at work, in which just a small change in wind speed multiplies to form a big wave. And certain areas of the ocean, like the strong waters off Africa's coast, may be more vulnerable to rogue waves than others...
Although the liberty of cinematic license may have shifted the development of Myozyme to Seattle, Genzyme’s real-life location in Cambridge is a crucial resource to the company and indicative of the city’s central role in the biotechnology industry...
