Oh dear! What is Al Gore going to do now? Instead of human caused global warming we might have nature caused global cooling or nature caused climate change. It just might happen. According to a NASA scientist, as reported by Alex Morales in Business Week , last week's powerfully devastating earthquake in Chileprobably shifted the Earth's axis and shortened the day, a National Aeronautics and Space Administration scientist said.Earthquakes can involve shifting hundreds of kilometers of rock by several meters, changing the distribution of mass on the planet. This affects the Earth's rotation, said Richard Gross, a geophysicist at NASA's Jet Propulsion Laboratory in Pasadena, California, who uses a computer model to calculate the effects."The length of the day should have gotten shorter by 1.26 microseconds (millionths of a second)," Gross, said today in an e-mailed reply to questions. "The axis about which the Earth's mass is balanced should have moved by 2.7...(Read Full Post)
