And even though the changes that occurred 19,000 years ago were due to increased solar radiation, that amount of heating can be translated into what is expected from current increases in greenhouse gas levels, and help scientists more accurately project how Earth's existing ice sheets will react in the future.

Translation - all that effort and they still refuse to learn from history - that solar radiation changes are what is driving current climate cycling.

You beat me to it! I would add that they had to find a way to spin this refutation of the “global warming” meme into support of it.

What I find amazing is that they are off by 13,000 years. The great lakes were formed a mere 6,000 years ago, accurately measured by the erosion taking place at Nigeria Falls. They found the interior of the falls erodes 3 ft a year, simple math calculates 6,000 year (stunning many scientists). A sheet of glacial ice covered over half the United less than 6,000 years ago. If they can’t even get this right, how correct can their assumptions be?
