Perhaps this is what you are looking forthis is what you are looking for. In particular, look at the bottom graph in red, which is an estimate of global ice volume. The data was taken from oxygen measurements in Antarctic ice cores.
Assuming they have their data and estimates close to right, it looks like our current worldwide volume of ice is not a record low for the Pleistocene. However, its pretty close to it. The end of the Oxygen (green) graph looks a bit wierd too. Still, there's nothing on the end of that ice graph that draws the eye to say, "something different is going on here".
