P.L.F. - Nuclear Summer

Years of darkness, the sunlight gone
Blocked out by the dust of civilization's incineration, or was it the Earth-shattering impact of an asteroid?
The smoke rose and blocked out the sun
Mankind's loss a mixed blessing
The grain has ceased to grow, generations forgotten in soot
Holes in the ozone, replete in skin cancer
The cataracts are blinding
The food supply has been frozen in summer
The seasonal shift is blinding
Following the settling of the aerosol, the sun re-emerges, blinding
Greenhouse warming is exponential
What life has yet survived, freezing in deformation, is now seared to death
The surface temperature is burning...
Not even our self-important corpses remain
The lonely oceans sit, spewing methane
