I was under the impression that Milankovitch cycles and other extraterrestrial,
"cosmic" factors had been fairly well established not to be the causes of
Earth's glacial periods, etc.
I agree that neither (1) global warming nor (2) peak oil are stand-alone,
exclusive reasons for our concern. There are also the other inter-related
matters of (3) global overpopulation vis-a-vis (4) fresh water depletion and
(6)cropland loss. Humanity must face them all soon, in a coordinated manner, or
our descendants will curse us unto eternity. Once again, to paraphrase our
misbegotten national "leaders", we must NOT wait until the smoking gun is in the
form of a... dead planet.
- We are all Human beings here together. We have to help one another, since
otherwise there is NO ONE who will help.
- All countries need a NO REGRETS strategic energy policy. Think ahead 7
