Sounds like a good read for a lazy day, yes ?
Until you read it and realize that this is the kind of stuff that AGW types write:
One Earth day is about 24 hours long. Over the course of a year, the length of day normally changes gradually by one millisecond. It increases in the winter, when the Earth rotates more slowly, and decreases in the summer, Gross has said in the past.Whose winter/summer has such a profound effect on the length of day ? Northern Hemisphere or Southern Hemisphere ?
There is actually a link in that "length of day" stuff that has an even smarter article on how the day is getting longer because humans are polluting the planet.
Another bright spot in the article that defies mathematics, and probably physics, is:
The 9.1 Sumatran earthquake in 2004, which set off a deadly tsunami, should have shortened Earth's days by 6.8 microseconds and shifted its axis by about 2.76 inches (7 cm, or 2.32 milliarcseconds).
8.8 earthquake that struck Chile....1.26 milliseconds.....also found that it should have moved Earth's figure axis by about 3 inches (8 cm or 27 milliarcseconds).
