Global Warming 5 Million Years Ago In Antarctic Drastically Raised Sea Levels

Posted by samzenpus on from the how-deeps-the-water-momma? dept.

An anonymous reader writes "As temperatures rise, scientists continue to worry about the effects of melting Antarctic ice, which threatens to raise sea levels and swamp coastal communities. This event, though, isn't unprecedented. Researchers have uncovered evidence that reveals global warming five million years ago may have caused parts of Antarctica's ice sheets to melt, causing sea levels to rise by about 20 meters."

    The interglacial periods coincide with variations in the earths orbit.
    eccentricity, tilt and precession all interacting. So yes it is pretty well understood why glaciation occurs. Yes it has been taken into account. No it does no account for the current changes being seen.
