have been made to explain the Ice Age cycles in terms of the combined effects of
the cyclical variations of the Earth's orbit, such as, the changing eccentricity
of the Earth's orbit around the Sun in 100,000-year cycles, and the 26,000-year
cycles of the precession of the Earth's spin axis, and the 41,000-year cycles of
the changing tilt of the spin axis. All of these factors affect the relative
distribution of the sunlight energy received by the Earth in the different
hemispheres, and also the intensity of the seasons (termed solar forcing).
computed combined effect of these cycles (the Milankovitch Cycles) somewhat
matches the Ice Age cycles, it had been assumed for a long time that these
orbital factors are
the causes for the Ice Age cycles. However, the Universe doesn't quite comply
with computed predictions. Too many irregularities have been observed. In one
case an interglacial began 10,000 years in advance of the computed causes. Here
we have a case of an effect, preceding a cause. Evidently the impossibility invalidates underlying failures in
ice age glaciation cycles with
the Milankovitch cycles added
immediate example of the observed non-compliance of the universe with computed
solar forcing is the missing reflection of the current weaker solar forcing that
has already dropped way below the level that has prevailed for most of the deep
cold period of the last glaciation cycles (see the light-blue line), for which
we should experience deep glaciation right now. But since this hasn't
materialized, a fourth factor is evidently superimposed that is more deeply
causative, and may in fact be causative of the orbital variations.
presently at a low point in solar forcing, or solar exposure (expressed in the
above diagram in watts per square meters at the top of the troposphere at 65
North in latitude). The current low value was only rarely reached and crossed
below during the historic glaciation cycles that we have ice core records for.
According to this conditioning, the Earth should be in a glaciation zone right
now, in terms of the Milankovitch Cycles. Since we haven't entered the
glaciation zone yet, we might be in the boundary zone right now, towards it.
This means the time has come to get ready to protect our agriculture, our prime
food source, in the most efficient manner possible.
