The Vikings lived in Greenland 'till in cooled.
Ten thousand years before, as glac'ers thawed,
Melt water in the North Atlantic pooled,
The Younger Dryas cold snap shocked and awed.
In Norway, glaciers reappeared on high,
Above the fjords where stoic Norse rule lapsed.
Then Carolina icebergs floated by,
As Greenland outlet glaciers collapsed.
Why would cold make this icecap melt, not grow?
Emotionless wind froze the Baffin Bay.
Warm currents thawed the ice tongues from below;
Without a shelf, the glac'er sped away.
Today such currents threaten the Antarctic
An outburst would be deluge, not cathartic.
