It now seems likely (Loutre and Berger, Climatic Change, 46: (1-2) 61-90 2000) that the current interglacial, based purely on natural forcing, would last for an exceptionally long time: perhaps 50,000 years. I'd read that article before, but had not grasped the above. I'd like to find out a bit more about that claim.

Having presented evidence that major changes in past climate were associated with variations in the geometry of the earth's orbit, we should be able to predict the trend of future climate Is it safe to assume that this has been done ?? ie A study of orbital dynamics as it relates to the timing of prior glaciations ?? I'm not aware that we have the ability to influence changes in the planet's orbit so; therefore, I assume that the scientific commmunity 'knows' where we are and where we're headed in the current climate cycle ?? Thus AGW would serve to either amplify or mitigate the natural cycle .. Triff ..
