Guest guest Posted November 4, 2008 Report Share Posted November 4, 2008 Polar Warming Shows 'Clear Human Fingerprint' An international research team reported last week that, for the first time, they have found evidence that a rise in polar temperatures is attributable to human activities. Their study involved analysis of temperature variations at both poles. Meanwhile, a satellite survey found that the thickness of Arctic ice has undergone an abrupt decline. Some scientists are worried that the greenhouse gases methane and nitrogen trifluoride, which are on the rise, may figure into our climate future more than anyone has considered. And researchers are using naturalist Henry David Thoreau's notes to ascertain patterns of plant abundance and decline in New England, with the hope of deciphering what it might tell us about changing climate. In other environmental news, a new study found that atrazine, a widely used agricultural weed-killer, increases the likelihood that flatworms will thrive in frog ponds and also inhibits the ability of larval frogs to fight infection with these parasites. For in a Republic, who is “the country� Is it the Government which is for the moment in the saddle? Why, the Government is merely a servant—merely a temporary servant; it cannot be its prerogative to determine what is right and what is wrong, and decide who is a patriot and who isn’t. Its function is to obey orders, not originate them. Mark Twain Quote Link to comment Share on other sites More sharing options...
