...worth each year--a development that is slowly but steadily raising global sea levels, and scientists worry that climate change could suddenly accelerate that vast melting. But the models indicate that ice loss should be happening on the western edge of the continent, where it is warmer, not in the much cooler east. No doubt there are complicated scientific reasons for this, but it pretty much boils down to what one researcher told a reporter: "There are some crazy things going down in Antarctica." It's a reminder that while the global-warming wars will continue, Earth has no obligation...
While the weather in Cambridge took a turn for the warmer this weekend, members of the Harvard nordic ski team headed north to Rangeley, Maine for one last race in the snow—a 50k-freestyle race at TD Bank Rangeley Lake Loppet...
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...
...warmer Franco-Russian feelings notwithstanding, reminders of Russia's independence - and frequent defiance of the West - remained apparent this week in Paris. Following Sarkozy's rather fiery remarks that a France-Russia partnership could help establish a new hard line on Iran's nuclear program, Medvedev responded tepidly, saying, "We will concentrate all efforts on finding political and diplomatic solutions," which he added had "not been exhausted yet." For his part, Sarkozy noted during the visit that Russia has still not fulfilled the conditions of its 2008 cease-fire with Georgia. (See pictures of the Russians in Ossetia...
Fedorov agrees that the new paper doesn't solve the puzzle of a warmer Pliocene by itself. "This is just part of the story," he says. "It's still the subject of intense research. We describe one piece of the puzzle, but there are many more pieces...
