Don,
Well you are disagreeing with scientist out of your expertise, in regard to the middle ages. As for the antarctica ice growing... The link you provided was from 2002, the same year the Larsen B ice shelf collapsed, I think we can eliminate that from the discussion. This is the link you provided: Note the date (2002), it was refuted by that major event that year. I guess that escaped the author. I would bet he was embarrassed. http://www.co2science.org//articles/V5/N40/C3.php "In February-March 2002 the Larsen B ice shelf, a mass of floating ice some 220 meters thick and larger than Rhode Island, broke up into icebergs. The flow of glaciers held behind the ice shelf accelerated. The ice shelf had probably existed since the last ice age. This was only the largest in a 30-year series of retreats of ice shelves along the Antarctic Peninsula, the only part of the continent that scientists had predicted would be affected soon by greenhouse warming." Do you want to see the satellite image? Do you believe this event a hoax? Do you have something more recent? Every report I have heard or read from Antarctica is that indeed the ice is receding on the coastal regions of the continent. This is the only thing Global Warming predicts (soon), and that snow fall may increase in the interior of antarctica. The article I gave a link to says this that makes the glaciers less stable adjacent to the ice sheets. It seems what is happening in Antarctica maybe the most alarming because they know so little about the glaciers. They have discovered the glaciers seem capable a very rapid motion (previously not believed possible a few years ago), and may be very active where the rubber meets the road.

This graph, I believe, does not properly show the Medieval Warm period.
And
the black curve projection did not occur - everyone knows 1998 was warmer than the following years.

Current global warming is also more confined to the northern hemisphere since the Antarctic ice sheet is growing. See my previous links
