Hansen
Experiment Shows by
Adrian Vance The
November 27, 1997 issue of the Journal of Geophysical Research includes a
research paper that should have ended the anthropogenic global warming
movement. Dr. James Hansen and 42
co-authors, all employees of Goddard Space Sciences Institute under Director
Hanson, published a paper entitled, "Forcings and Chaos in Interannual and
Decadal Research," in the Journal of Geophysical Research. It describes a failed attempt to find causes
Hansen dubbed "forcings" of climate change among the chaotic
components of climate. The
43 authors wrote, "Scientists and lay persons have a predilection for deterministic
explanations of climate variations. However, climate can vary chaotically, without
any “forcings,” the slightest alteration of initial or boundary conditions. Future weather is inherently unpredictable.
This behavior is the reality of the nonlinear fundamental equations governing
the dynamics of such a system." It
would be more accurate to say all factors and systems interact in so many ways
it is not possible to make predictions. In
this time serious climate modeling is impossible, ridiculous or criminal. The
authors' experiment took three major computer modeling systems for climate and ran
them with no forcings for the period 1979-1996, then compared the result to the
observed average annual temperature of the stratosphere, troposphere (lower
atmosphere), and sea surface. Average
temperature was chosen because it is a meaningful product of the effects. Then
they added forcings, external perturbations, to see if the models were closer
to observed values. If they did, they would
claim forcings have an effect independent of chaos. The five forcings included: stratospheric
aerosols from volcanoes, greenhouse gases, ozone depletion, the solar cycle and
the heat imbalance postulated to be due to the effect of greenhouse gases before
1979. While
the experiment worked to some degree for the stratosphere and the sea surface,
where air is thin, dry and simple, it failed in the troposphere, where climate changes
are greater. For the most sophisticated
system, the unforced case yields a correlation with observation of +0.26, a
positive, but poor correlation. A
correlation of +0.26 is not a probability, but a relative ranking on a scale
where +1.0 equals full correlation and -1.0 is complete disagreement. Decimal correlations are relative and
subjective not quantitative and objective like percentages in probability. Adding
forcings in the order above yielded correlations of +0.23, +0.34, +0.34, +0.26
and +0.13, respectively. In fact, the
only model to exceed a +0.50 correlation is the troposphere in which the
unforced mode hits +0.59. When forcing
is added, the correlation dips to +0.19, much less. The
data shows “climate is chaotic and effects of long-term forcings, like “greenhouse
gases,” are essentially unpredictable and undiscernible." The
objective to confirm climate is warming is caused by an increase in greenhouse
gases independent of natural climate variations that Hansen and his 42
co-authors tried to demonstrate failed. These
computer models were used at -30- |
