Yes we do, and the "very brief period" we are currently in is about 11,700 years.[1] Your point? Edit: "FSM my point is shouldn't we be worrying about ice-ages not global warming" No we shouldn't, you are just being an "alarmist" ;)

And this mean human activities can't affect the climate over the next few centuries? Ah, I get it now. If you see a fire you don't put it out. You wait for it to destroy the building, then simply rebuild it ...

You do realize that your link shows a time frame of 425,000 years. If you were to stretch out that graph to a scale in which you could actually see a human lifetime, the lines would be close to horizontal. < Where do you get 30.000yrs from? an average interglacial lasts 10 to 11 thousand years, we are overdue.> Why are we overdue? The little ice age in the mid 19th Century happened right on schedule. Global average temperature was just as low as it was 6,000-8,000 years after any interglacial maximum. If the next ice age is delayed, it would be for one of the following two reasons. And where did 30,000 years come from? From you graph. 1. We build cities, by accident or design, in key locations, the urban heat island effect will prevent snow from remaining throughout the summer. 2. If there is no mechanism to return the carbon dioxide which we released by burning of fossil fuels.
