...antisocial or violent behavior - such as smoking, alcohol use, relationship problems and poverty. "It's depression during pregnancy that seems to set the child on taking a violent path," says Dale Hay, a professor of psychology at Cardiff University in the U.K. and the lead author of the paper. (See "The Year in Health 2009: From...
...more more unstable, reflected in sudden rising and falling of the sea level. "It's fair to say that this means glaciers may change somewhat faster than we once inferred," says Jeffrey Dorale, a geoscientist at the University of Iowa and the lead author of the Science paper. "It does suggest there can be very fast is melting and very fast ice building at times when CO2 levels were lower than...
...radiation hitting the planet's surface. "The sea-level high may be considered an exception to the 100,000-year cycle, in which high summer sunlight caused the ice sheets to melt," writes R. Lawrence Edwards, a geologist at the University of Minnesota, in a commentary on the Science paper...
...Antarctica will respond to warming temperatures. The science is so foggy that the Intergovernmental Panel on Climate Change - which recently came under attack for hyping the impacts of global warming - has refrained from estimating how fast those ice sheets could melt and contribute to sea level rise. Dorale's paper suggests the possibility that ice sheets may respond much more dynamically to changes in temperature, forming and melting at rates that are quicker than previously thought. "There might be a feedback with regards to ice melting," says Dorale. "This is speculation, but it might point at some sort of catastrophic...
...defend him, who say it is not a big deal," says Lancelin. Indeed, the Libération newspaper, for which Lévy is an editorial consultant, has already backed off the story. "It often happens, even in rigorous universities, that one is duped," a journalist for the paper wrote this week. "In the case of Bernard-Henri Lévy, the affair has risen to a real fracas." But for critics like Lancelin, Lévy shouldn't be able to get off that easy. "In fact, it was an inexplicable oversight," he says...
