The question is, Barbarian, how does one accumulate ice on areas that are not at the poles.
Greenland is not at either pole. But northern latitudes do allow for continental glaciation. Just a few degrees change in average temperature can initiate glaciation.
While you assume Australia was near the South Pole,
That's what the evidence, from many different sources, indicates. Want to learn about them?
how do you account for ice accumulation away from the poles.
Continental ice sheets can form over large areas quite a long distance from the poles, even if it's a relatively warm period like the current one. Smaller ice accumulations can form on the top of high mountains. You never see continental glaciation like that, though.
Even the biggest alpine glaciers are quite tiny compared to the things you're talking about.
