Figure D2 RELEASE

Downward to a well sunk deep below

The ocean’s surface, in a rattling cage

Of iron bars— here, as white as snow,

In ice is trapped, by pressure and long age,

A treasure and a peril: history’s page

May show this methane, product of the sun,

As worthy of our poor descendants’ rage

As we may be. Let it not be undone,

A fearful form of feedback, this, the CLATHRATE-GUN.
