There we go again Kilts/Observing?? another useless peice of "Contradiction" this time without the TANTRUM!........Saying that the equator wasnt affected is total RUBBISH and a fallacy if you believe in the scientific approach! If your going to call people idiots make sure you dont look like one first!
The latest 'scientific' see herehttp://www.abc.net.au/science/articles/2007/12/06/2111168.htm
Instead of 'snowball earth', the planet really became 'slushball earth'.
Professor Richard Peltier and colleagues from the University of Toronto publish their hypothesis today in the journal Nature. The great chill, the longest and deepest ice age in earth's known history, happened during the late Neoproterozoic era, 850 to 542 million years ago.
The evidence for the snowball thesis comes from deep sediments in the ocean. Scientists look through these layers to measure levels of the isotope carbon-13 (C13), deposited in plants through photosynthesis, as a telltale of earth's climate. Above and below the era's Cryogenian layer is an abundance of C13. But the Cryogenian layer itself has negligible levels of this isotope.
Coupled with other signs of intense glaciation, the explanation is that earth froze over completely.
According to the 'snowball earth' hypothesis, thick ice covered the oceans and glaciers crept down into the tropics, even reaching the equator.
