Greenland Ice

If you went to Greenland, almost 80 North,
And drilled your way down … a mile, then more,
You’d find some strange layers, a story’d come forth
A record of ice ages locked in a core.
You’d find glacial ice that is clearer, more soft
Than Eemian ice (long crystals, more rigid)
And clues that the ice height was higher aloft
Than thought for that time (with air temps less frigid).
A puzzle indeed, this view down a hole —
If NEEM endured warmth, whence the sea rise?
Some question the records, some look to South Pole …
In the decades that come, are we in for surprise?
