"It is a cold fact: the Global Cooling presents humankind
with the most important social, political, and adaptive
challenge we have had to deal with for ten thousand years.
Your stake in the decisions we make concerning it is of
ultimate importance; the survival of ourselves, our children,
our species" (Lowell Ponte, 1976)
