85% of Time CO2 does not Correlate with Temperature!
The HadCRUT global temperature dataset that the IPCC references contains instrumental
records that date back to the year 1850. Precise CO2 data (measured in tenths of
parts per million) from thousands of years ago can be found in Antarctic ice cores,
with direct measurements (Mauna Loa) available since the 1950s. In comparing the
two records, it can be concluded that during the last 165 years, rapidly increasing
CO2 concentrations only correlate with rapidly increasing global temperatures for
one 25-year period (1977-2001). Put another way, for 85% of the last 165 years
there has been little to no correlation between CO2 concentration changes and temperature
changes. - See more at: http://notrickszone.com/2016/08/04/non-existent-relationship-co2-temperature-correlation-only-15-of-last-165-years/
The Bottom Line About "Climate Science" and "Global Warming"
The following image is my version of one presented to the public, on USAToday, in
October 2010). It embodies, for me, the central truth about "global warming" and
the "climate science" behind it, that everyone (particularly any "expert" who defends
it, and any politician--like President Obama or his Attorney General--or dogmatic
ideologue who demands obedience to it) needs o know and accept:
The original image purported to show that the "global temperature" (more correctly,
the global mean surface temperature, or GMST) has increased with the increase in
atmospheric CO2 concentration, since 1880.
Note, in the graph, that the temperature is shown as apparently closely tracking
(to the eyes of the unwary, non-scientific layperson) the rise in CO2, from about
1975 on (to the end of the graph, about 2008). I say the temperature "apparently"
tracks the CO2, because the scales of the two superimposed graphs have been selected
to show just that (again, to "make it clear" to the non-scientist reader). The trouble
is that the temperature data is very noisy, making that "jittery" appearance in the
temperature graph, and it doesn't really follow the smooth CO2 curve all that well,
particularly from 2000 on.
Now, honest scientists can legitimately argue over just how well or how bad the temperature
tracks the CO2 from 1975 on, based solely upon this illustration as presented to
the public by leading climate scientists. What cannot be honestly argued about, however,
is that the temperatures BEFORE 1975 do NOT track the rising CO2; they vary, both
positively and negatively, independently of the ever-rising CO2. That is the first
simple, and devastating, point to be remembered by everyone, even those who are uninterested,
or uneducated, in the debate.
This was so apparent to me, when I first came upon this image, that I posted the
"The graph shown here arbitrarily puts the CO2 curve on top of the temperature record
so that the two curves rise together after 1979--but only after 1979, note. As an
independent scientist, I do not hesitate to call this what it is: fraudulent science.
This is very ugly, raw political propaganda in the name of science. All scientists
should be repulsed, and ashamed, by the breadth and depth of the incompetence in
their midst, and the foisting of that incompetence upon the public."
Since the public debate was not about the science, but was and is in fact a political
war, my small voice for real science was ignored, as it has been by most ever since.
