For fifty million years, ‘tis understood
A vanished forest froze in permafrost.
The isotopes of carbon in the wood
Tell secrets of the climate we have lost.
Then brackish duckpond, now a frozen sea,
Those Rains of Castamere, we can’t agree:
Cold drizzle or a tropical monsoon?
Extinct sequoia yearns for rain no more
Yet in its fossil rings it has preserved
A dryad’s weather journal, yielding lore
of summer rain and winter drought observed
Arctic Ocean’s lost half of its ice
What happens when it’s gone? We need advice.
