Behind the clouds does light emerge

Behind the clouds does light emerge
  Casting burgeoning gold shapes
In welkin chiaroscuro
  O'er dead, obscure, cured, or chaste.

All generative rains beget
  Set forgetting in their seed.
The deep condition, where saltsea
  Surfeits with its solute's speed.

With these penultimate remains,
  Changes jettison in time
A race before they are deranged,
  Altered for a danger's dime.

Invisibly their fuel destroys,
  Poisons future lives whose dooms
They're unaware of, of peril
  Decades after petrol plumes.

And as below is it above,
  Of a change so subtle eye
Cannot discern nor can suspect
  Acid from a spectral sky.

There's concrete with the roots beneath
  Teeth of infrastructure. Growth,
Conditioned and evolved, belied
  By the two, and blithe as both;

Which interstructure since contorts,
  Torques askance the psyche's clime.
Its gaseous hand distorts terrain
  Of mind, body, taints with time.

The consequences we invent
  Seven hundred million years
Hence still will reach to each foxhole.
  We'll have been gone. Fossils, fears.
