Here is a link that describes the thickness of
the Greenland ice sheet;

http://en.wikipedia.org/wiki/Greenland_ice_sheet

Someone said "where I live the ice was a mile thick 20K years ago"

That was me.

I have to assume he meant some city in a well populated area, not some
area unpopulated like an ice shelf.

Why would you assume that, there is no evidence
of a well populated area or city from 20,000 years ago.

Again I ask, does anyone want to lay claim that where they live now,
20K years ago their wa ICE a "mile thick"?

Anybody in Ohio, Indiana, southeastern Canada,
maybe the Netherlands and Belgium and many other
places can claim that based on paleogeology studies.

I can re-quote the posting if needed.

So can I, is there any question about North America
and parts of Europe having an ice sheet as thick as
Greenland today?

With all the clickable links I posted, isn't the
accepted ice sheet data good enough?

There was global warming 20,000 years ago,
up until about 8,000 years ago, and smaller cycles
since then.
And there were very few men burning coal
or oil then.
