If you have been lulled into a sense of complacency by Milankovitch orthodoxy, namely that we have dodged a plummet into another glaciation and that we have about 100,000 years of "smooth sailing" ahead of us because of the projected low eccentricity of the Earth's orbit, head over to ScienceDaily and dig up an article from 2002 titled "Increasingly Salty Mediterranean Favors Ice Sheet Growth".
