==================
It's a long way from being "incontrovertible", your trying to slap down
the last two million years of history telling that the Earth is vast
majority 'Ice Age' now (averaging a hundred thousand years and more) with
much shorter interludes, shorter summer interludes one might say, of global
warming (a few short tens of thousands of years of warmth -- varying from
around fifteen to about thirty-five thousand years; and even those
interludes now being liberally laced with mini-ice ages).
Yes climate has changed for the Earth over billions and millions of years.
The trend over the last few million years is toward fewer interludes
lessening in warmth with longer periods (into hundreds of thousands of
years) of global deep freeze. Not only is Earth's immediate environment in
constant change, but so is the environment external to Earth in constant
change (particularly the Sun's immediate environment. And probably even the
local interstellar environment, which our Sun and our Solar System, and thus
our Earth, may be more sensitive to than we would like to think).
