They didn't talk about this too much , but they did have a 5 minute segment on Sandra Bullocks new Baby she adopted, which I guess is NEED TO KNOW information for America.....
Notice how all these people are being exposed of cheating and what not....
It's the new thing for 2010........it will be what keeps our attention away from the real thing going on, like oil spills......
Even under the Clinton Administration they would have handled this much better.....

There are many scientists, though not very popular, who postulate that what killed the dinos was not an astroid but a methane eruption.
In what sounds like a scene from a Hollywood disaster film, scientists looked over the side of the Russian research vessel Yacob Smirnisky to view the ocean foaming as huge ancient deposits of methane, a greenhouse gas 20 times more potent than carbon dioxide, began to thaw and bubble to the surface. The alarming reports of what the International Siberian Shelf Study 2008 have been witnessing over the last few days were sensationally revealed by Britain's Independent Newspaper two days ago (23rd September 2008). As the newspaper reports this is the first evidence that millions of tons of methane are beginning to be released into the atmosphere from beneath the Arctic Ocean.
The intense concentrations of the greenhouse gas, some up to 100 times background levels, were discovered in the East Siberian Sea and the Laptev Sea, an area some tens of thousands of square miles in the Siberian continental shelf. The Independent published extracts from emails sent from one of the lead researchers aboard the Yacob Smirnisky, Orjan Gustafsson of Stockholm University:
Massive stores of methane, which formed before the last ice age, are locked away beneath the permafrost of the northern hemisphere. Produced naturally by the decay of water-logged vegetation, over millennia the methane deposits have accumulated beneath the land and ocean, removing huge quantities of carbon from the atmosphere. Permafrost at the sea floor had acted like a lid to prevent the huge methane deposits, from escaping. It's thought that this new phenomenon is related to the rapid warming that the Arctic region has experienced in recent years.
Methane-trapping ice of the kind that has frustrated the first attempt to contain oil gushing offshore of Louisiana may have been a root cause of the blowout that started the spill in the first place, according to University of California, Berkeley, professor Robert Bea, who has extensive access to BP p.l.c. documents on the incident. If methane hydrates are eventually implicated, the U.S. oil and gas industry would have to tread even more lightly as it pushes farther and farther offshore in search of energy. Drillers have long been wary of methane hydrates because they can pack a powerful punch. One liter of water ice that has trapped individual methane molecules in the "cages" of its crystal structure can release 168 liters of methane gas when the ice decomposes. Bea, who has 55 years of experience assessing risks in and around offshore operations, says "there was concern at this location for gas hydrates. We're out to the [water depth] where it ought to be there." The deeper the water, the greater the pressure, which when high enough can keep hydrates stable well below the sea floor. And there were signs that drillers did encounter hydrates. About a month before the blowout, a "kick" of gas pressure hit the well hard enough that the platform was shut down. "Something under high pressure was being encountered," says Bea—apparently both hydrates and gas on different occasions.
Workers from Halliburton who had just pumped cement into the well to temporarily seal it off were well aware of the potential hydrate hazards, says Bea. Halliburton just last year had developed strategies to avoid having the heat of curing cement decompose any nearby hydrates and trigger a kick, he says. A special foamy cement was used to seal the well this time. It was just after the seal was tested that natural gas drove through it, a malfunctioning blowout preventer, and a drill pipe full of seawater to ignite on the platform, killing 11 and eventually sinking it. "There are so many operations like this around the world," says Bea. "My hope is we'll use this disaster as an opportunity to take a step forward" in risk reduction.
